Operation/Screens/Cleaning Casement and Awning Windows C ASEMENT AND AWNING w i n d o w s O p e rat i o n Pella® Impervia® casement windows feature a convenient locking system — a single, easy-to-reach sash lock handle operates both window locks. To open the window, just lift the sash lock to unlock the window, then pull out the fold-away handle and rotate it. Be sure to unlock the window before you try to open it — otherwise, you’ll risk damaging the operating mechanism. To close the window, reverse the steps. Be sure to lock the sash whenever the window is closed; it will ensure the window is properly sealed. Awning windows are similar to casement windows turned on their sides. Awning windows are designed to be opened to a 45° angle or less. If you prefer a different look, casement and awning handles and lock levers can be replaced with hardware in a different color/finish. See the Pella Window and Door Showroom nearest you for details. Sc re e n s Flat screens Full standard fiberglass Removing the screen from the interior of the house/building requires two hands. Pivot the screen latch clips out of the grooves on the side of the window frame. While holding the screen latches securely, carefully bring the screen into the house/building. Installing the screen from the interior of the house/building requires two hands. Make sure the screen handle and screen latch clips are facing the interior, and then position the screen in the window frame. Pivot the screen latch clips into the grooves on the sides of the window frame to hold the screen in place. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. CAUTION: To help avoid scratching the fold-away handle or window frame, make sure the screen latches are fully retracted when removing or installing screens. Cleaning Cleaning the glass To wash the glass: 1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft, clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex® (clear liquid) or Sparkle® (purple liquid). Feel free to be generous with the amount of cleaner you apply, but avoid getting any cleaning solution on the fiberglass frames as it may discolor the finish. 2. Rub from several different directions. 3. Rinse with clear water if streaks remain after cleaning. CAUTION: Do not use glass cleaners that are ammonia- or alcohol-based. They may leave streaks or produce a film that attracts moisture or dust. 1.1 Casement and Awning Windows Cleaning Spot-cleaning stubborn materials on all glass To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the glass: 1. Apply a small amount of a nonabrasive cleaner such as Bar Keepers Friend® (SerVaas Laboratories) to a clean, wet cloth — or apply a solvent such as acetone or mineral spirits to a clean, dry, lint-free microfiber cloth or paper towel. 2. Rub on the areas of glass that need spot-cleaning. Avoid getting any cleansers or solvents on the fiberglass frames as they may discolor the finish. 3. Wipe clean using a clean, dry, lint-free microfiber cloth or paper towel. 4. Then clean the glass as instructed on page 1.1. CAUTION: Do not use a razor blade to scrape off stubborn materials — doing so may leave permanent marks on the glass or scratches that could cause glass breakage. Contact the Pella Window and Door Showroom nearest you for special cleaning instructions. Spot-cleaning marks on a SunDefense™ Dual Low-E room-facing glass surface Occasionally, a mark may appear on the interior of Dual Low-E glass due to metal coming in contact with the surface. Most often, this is not a scratch and can be removed using the following instructions: 1. Apply undiluted white vinegar to a soft, clean, lint-free microfiber cloth or paper towel. 2. Rub the marked area from several different directions. 3. If the mark still remains on the room-facing Low-E glass surface, apply a small amount of Bar Keepers Friend® or Cerama Bryte® Ceramic Cooktop Cleaner to a soft, clean, lint-free microfiber cloth or paper towel. Avoid getting any cleansers or solvents on the fiberglass frame as they may discolor the finish. 4. Rub the marked area again from several different directions until it disappears. 5. Then clean normally as instructed on page 1.1 “Cleaning the glass.” NOTE: Some marks may require repeating this process. Cleaning egress windows Some windows have optional emergency-exit (egress) hardware identified by red “Open” labels. These windows are designed to provide a wider opening when fully opened. To wash casement egress windows: 1. Unlock the sash and crank the roto-operator to position the roto-operator shoe against the “Wash” label on the egress operator slide. 2. Push the bottom release levers outward to release the hinges. 3. Slide the edge of the sash toward the center of the window opening. The sill hinges will lock in place and position the sash for washing. 4. The release lever will automatically reset when the window is closed. 1.2 Cleaning Casement and Awning Windows Cleaning flat screens Full standard fiberglass To clean a flat fiberglass screen, either remove the screen (see page 1.1) and gently wash it with soap and water, or use the drapery brush attachment on your vacuum cleaner. Vivid View® high-transparency screens To clean Vivid View screens, remove them from your windows and hose them off with water. NOTE: The ultrafine screen material is more delicate than fiberglass or aluminum screens and should be handled with care. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. CAUTION: Do not power-wash. Cleaning the interior frame and sash material To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the interior of your frame and sash material, clean the surface with warm, soapy water. For best results on stubborn stains, Pine-Sol® should be applied with a clean, dry cloth or towel. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you. WARNING: Do not use abrasives. Do not scrape or use tools that might damage the surface. Cleaning the exterior frame and sash material Clean the surface with warm, soapy water. Stubborn stains and deposits may be removed with mineral spirits. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you. WARNING: Do not use abrasives. Do not scrape or use tools that might damage the surface. Do not power-wash. Cleaning the weatherstrip Frame weatherstrip and sash rainstrip should be wiped down with warm soapy water annually to ensure maximum window performance. Cleaning the hinge slide The hinge slide at the sill (bottom) of casement windows and on the side of awning windows should be lubricated twice a year to remove dirt and debris. The hinge slide should be lubricated with WD-40 penetrating oil or silicone dry film lubricant to ensure smooth operation. Cleaning the hardware finish A soft cloth and mild cleaner may be used on all hardware finishes for Pella® windows. NOTE: Oil-Rubbed Bronze window hardware is a living finish that will develop its own unique patina with use, care and handling. 1.3 Sliding Windows Operation/Screens/Grilles/Cleaning sliding windows O p e rat i o n To open the window, unlock the lock located in the middle of the venting sash. Larger windows may have two locks. Push or pull at the center of the venting sash to open the window. To close the window, push or pull at the center of the venting sash to return it to the closed position and lock the window. Reengaging the lock will automatically align and center the sash together for a tight seal. Sc re e n s Removing a screen will take two hands. To remove the screen from the interior of the house/building, fully open the venting sash. Holding the screen handle with two hands, push the screen frame left or right toward the center of the unit and then push the bottom of the screen frame toward the exterior of the house/building. This should release the screen from the track. Carefully tilt and turn the screen so it fits through the open window. Then pass the screen through the window to the inside of the house/building. To replace a screen, reverse the process above and make sure the handle is engaged. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. G ri l l e s Permanent grilles Aluminum grilles-between-the-glass The aluminum grilles-between-the-glass are permanently installed between panes of glass, so they stay clean and never need to be removed. Cleaning Cleaning the glass To wash the glass: 1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft, clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex® (clear liquid) or Sparkle® (purple liquid).

Unlock the window and slide to the fully opened position (1). Make sure that the sash has cleared the anti-lift clip, which is a security feature that prevents removal of sash when closed, located at the top of the frame (2). Lift the sash up and out of the bottom track, then tilt in the bottom of the sash until it clears the frame (3). 1 2 CAUTION: Sash may be heavy. Lay sash flat to wash the exterior glass on the vent panel. To wash the fixed panel from the interior of the building, remove the screen and reach out to wash the exterior glass. CAUTION: Do not extend your body out of the window. If the entire glass of the fixed panel cannot be reached from the interior of the house/building, wash the fixed panel from the exterior of the house/building. When reinstalling the sash, be sure to insert the top of the panel into the frame in the fully open position 3 so that you clear the anti-lift clips, then rotate the bottom into position. Close and lock the sash a few times to ensure proper operation. For exterior glass-cleaning solution, follow the “Cleaning the glass” steps on page 2.1. Spot-cleaning stubborn materials on all glass To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the glass: 1.

Set the sash in a safe place until you are ready to reinstall (3). Caution: Sash may be heavy. 1 2 3 4 5 6 7 8 Locate the sill track in the bottom inside channel of the window. If you use a vacuum cleaner with the brush attachment to clean out the debris in the track, the sash will be easier to operate. • Insert a stiff-bladed putty knife between the interior of the frame and the sill track, and pry upward to start removal (4). Once started, grab the sill track and lift upward to complete the removal of the track (5). • Vacuum out any debris and thoroughly clean the sill channel with warm, soapy water prior to reinstalling the sill track. Flush out the weep system by slowly pouring a few quarts of rinse water into the sill channel (6). The water should drain readily to the exterior (7). • Starting at one end and continuing along the entire length, push the sill track down to snap into place (8). Be sure that both the interior and exterior sides of the sill track are snapped fully into place. Lightly tapping a block of wood with a rubber mallet along the entire length will help ensure that the sill track is in place.

Rub on the areas of glass that need spot-cleaning. Avoid getting any cleansers or solvents on the fiberglass frames as they may discolor the finish. 3. Wipe clean using a clean, dry, lint-free microfiber cloth or paper towel. 4. Then clean the glass as instructed on page 4.3. CAUTION: Do not use a razor blade to scrape off stubborn materials — doing so may leave permanent marks on the glass or scratches that could cause glass breakage. Contact the Pella Window and Door Showroom nearest you for special cleaning instructions. Spot-cleaning marks on a SunDefense™ Dual Low-E room-facing glass surface Occasionally, a mark may appear on the interior of Dual Low-E glass due to metal coming in contact with the surface. Most often, this is not a scratch and can be removed using the following instructions: 1. Apply undiluted white vinegar to a soft, clean, lint-free microfiber cloth or paper towel. 2. Rub the marked area from several different directions. 3. If the mark still remains on the room-facing Low-E glass surface, apply a small amount of Bar Keepers Friend® or Cerama Bryte® Ceramic Cooktop Cleaner to a soft, clean, lint-free microfiber cloth or paper towel. Avoid getting any cleansers or solvents on the fiberglass frame as they may discolor the finish. 4. Rub the marked area again from several different directions until it disappears. 5. Then clean normally as instructed on page 4.3 “Cleaning the glass.” NOTE: Some marks may require repeating this process. Cleaning flat screens To clean a flat fiberglass screen, either remove the screen (see page 4.1) and gently wash it with soap and water, or simply use the drapery brush attachment on your vacuum cleaner. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. Cleaning the sill To remove dirt or debris on the sill of the window, open the lower sash approximately 4" to 5" and use a vacuum cleaner with the brush attachment to clean off the debris. Cleaning the interior and exterior frame and sash material Clean the surface with warm, soapy water. Stubborn stains and deposits may be removed with mineral spirits. Do not use abrasives. Do not scrape or use tools that might damage the surface. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you. WARNING: Do not use abrasive or caustic solvents as they may damage your windows. Do not scrape or use tools that might damage the surface. Cleaning the hardware finish A soft cloth and mild cleaner may be used on all hardware finishes for Pella® Impervia® double-hung windows. NOTE: Oil-Rubbed Bronze window hardware is a living finish that will develop its own unique patina with use, care and handling. 4.4 Sliding Patio Doors Operation/Screens/Grilles SLIDING PATIO DOORS O p e rat i o n Thumbturn locking system You can find the thumbturn lock on the interior side of the flat panel behind Unlocked Locked the door handle. To lock the door, fully close the sliding panel and turn the thumbturn to a vertical locked position. To unlock the door, turn the thumbturn in the opposite direction. Sc re e n s Pella® Impervia® sliding screen doors are top-hung, which should provide years of easy operation because dirt and debris will not build up in the head track like it can on bottom tracks. To remove the screen door for storage, remove the two screen hanger screws in the top rail of the screen with a Phillips screwdriver (1). Tilt the top toward the interior, then lift up until the bottom guide is out of the sillframe track (2). To install the screen door, insert the bottom screen guide in the sill of 1 2 the frame track. Keep the guide in the frame track, and tilt the top of the screen up against the door panel. Align the two screen hanger screws with the holes in the screen carrier. Turn each screw approximately twice to adjust them (1). Turn the screw clockwise to raise the screen until the pile insect strip on the exterior of the screen’s top rail touches the screen track. Slide the screen to within 1" of the lock side of the door. The space between the screen and the lock side of the door should be equal from the top to the bottom of the screen. If the space is not equal, adjust the screen hanger screws. Note: Do not adjust too high or too low, or the screen will not slide properly. Check the screen operation. Ensure the screen operates and latches smoothly. The lock on Pella Impervia sliding patio screen doors is operated manually. Slide the lever down to lock and up to unlock. WARNING: Use caution when children or pets are around open windows and patio doors. Screens are not designed to retain children or pets. G ri l l e s Permanent grilles Aluminum grilles-between-the-glass The aluminum grilles-between-the-glass are permanently installed between panes of glass, so they stay clean and never need to be removed. 5.1 Cleaning Sliding Patio Doors Cleaning Cleaning the glass To wash the glass: 1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft, clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex® (clear liquid) or Sparkle® (purple liquid). Feel free to be generous with the amount of cleaner you apply, but avoid getting any cleaning solution on the fiberglass frames as it may discolor the finish. 2. Rub from several different directions. 3. Rinse with clear water if streaks remain after cleaning. CAUTION: Do not use glass cleaners that are ammonia- or alcohol-based. They may leave streaks or produce a film that attracts moisture or dust.

Since the sash cannot be removed, the exterior must be cleaned from the outside. For additional cleaning instructions, please reference previous sections. RE C OMMENDED MAINTENAN C E Ov e rv i e w Pella® Impervia® Windows and Patio Doors Pella recommends you inspect your windows and doors at least annually as part of a home checkup. Recommended maintenance can prolong the life of your Pella Impervia windows and patio doors and will help ensure maximum warranty coverage. As needed, clean your windows and patio doors, and recaulk around the perimeter to help maintain optimal performance. Also be sure to check for leaks regularly, improper drainage above or around vents, and sprinkler systems that may subject your windows and doors to prolonged water exposure. With recommended care, Pella Impervia windows and patio doors and Special Shape windows can reward you with many years of beauty and performance. Exterior An annual checkup can help preserve and maintain the beauty of your Pella Impervia products for years to come. Inspect the sealant/caulking on the exterior perimeter of your windows and patio doors at least once a year. The sealant/caulking helps create a watertight seal between the window and door frames and the exterior siding (whether it is vinyl, cedar, aluminum, brick, etc.) or stucco. It is extremely important that the sealant/caulking remains intact and in good condition at all times. Pay particular attention to the caulking at the lower corners of windows and under joints between windows in combinations (a grouping of individual windows). The sealant material should not be cracked, broken or missing — or it may cause premature failure of your Pella Impervia products or other parts of your home. Deterioration that occurs as a result of improper or insufficient maintenance is not covered by the Pella Impervia Limited Lifetime Warranty.* Pella Impervia windows and patio doors arrive prefinished. Check the paint, and if the surface is damaged, the exposed areas must be repaired immediately to prevent further damage. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you. If you need further assistance, contact your local Pella representative. Please note that if you do paint over the factory finish, Pella’s paint warranty is voided. Interior finish At least once per year, inspect the interior finish of your windows and/or doors to make certain that the finish is in good condition. UV rays from the sun can break down the finish and compromise its protective features. Pella Impervia windows and patio doors arrive prefinished.

Cleaning the weatherstrip To remove any deposits — such as grease, oil or stains — that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner — such as Spray-n-Wash®, OxiClean® Fabric Cleaner or Resolve® Carpet Cleaner — to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. * See written warranty for complete details on Pella Impervia products, or visit http://warranty.pella.com. 6.1 Recommended Maintenance Double- and single-hung windows To remove any deposits — such as grease, oil or stains — that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner — such as Spray-n-Wash®, OxiClean® Fabric Cleaner or Resolve® Carpet Cleaner — to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants to clean the weatherstrip; they attract dust and grime, which will eventually restrict the window’s movement. Sliding windows Use the drapery brush attachment on your vacuum cleaner to clean the track. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the window’s movement. Sliding patio doors For proper operation, keep the door track free of debris. The thumbturn lock and strike and rollers on the venting panel are adjustable to improve operation. Keep the weatherstrip clean and lubricated to enable the panel to operate smoothly. You may want to apply a thin coat of paraffin or other dry lubricant (Teflon® Dry Lubricant or Gulf Wax®, available at most home improvement stores, works well) to prevent sticking. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the door’s movement. Sliding screen doors Pella® screen doors are top-hung — it is important to keep the upper and lower door track free of dirt and debris. The rollers on the top of the screen can be adjusted if necessary. (See page 5.1 for detailed instructions.) If the screen becomes dirty, you can clean it using a vacuum cleaner with the drapery brush attachment. Do not use oily lubricants to clean the track; they attract dust and grime, which will eventually restrict the door’s movement. Salt spray environments The seacoast environment is extremely hard on all sorts of products (automobiles, recreational vehicles, building products, etc.). Any product used in a seacoast location will require more frequent inspection and maintenance to help it last as long as possible in this harsh environment. Windows and doors are no different from other products in this respect. If your home is in a coastal environment and is subjected to wind-driven salt spray or salt fog, use a mild detergent soap and water to clean the exteriors, including operating hardware, at least quarterly — and more often if necessary — to prevent salt or other abrasive materials from building up on the exterior surfaces. CAUTION: Do not power-wash. 6.2 Troubleshooting TROUBLES H OOTING Ov e rv i e w If you have a concern with your Pella® Impervia® product or need additional assistance from an experienced professional, consult your Yellow Pages (under “Windows”) for the Pella Window and Door Showroom nearest you or use the store finder at pella.com. Glass breakage/damage In the event of glass breakage, consult the Pella Window and Door Showroom nearest you for assistance. Be sure to have your Pella Unit ID Number handy (see page 7.4). For safety reasons and to ensure optimum performance, we strongly advise you to consult a professional for glass replacement. U.S. federal law and most local codes require the use of tempered glass in doors and other specific applications. Tempered glass can withstand greater impact than ordinary glass, but it is sensitive to scratches. Scratches can cause immediate or delayed breakage. If the glass is tempered, it will break into small, rounded pieces. If tempered glass is broken, likely by law it must be reglazed or replaced with tempered glass. Sliding windows The sash is hard to open and close. The sash rolls on a track inside the frame. Over time, dirt and debris can get in or on the track, making it harder to open and close the sash. Removing the sash and using a vacuum cleaner with the brush attachment to clean out the debris in the track will make the sash easier to operate. The sash is hard to remove. Remove the venting sash. (See page 2.2 for detailed instructions.) On the bottom of the sash are two sets of dual nylon rollers. With needle-nose pliers, gently shift the wheels to the other notch location. This will raise the sash rollers by 1/16", allowing for the operating sash to move freely. Note: The roller housing does not have to be removed from the sash to adjust the roller location. This was done for illustration purposes only. Single-hung windows The sash is hard to open and close. The sash will slide inside the frame. Over time, dirt and debris can get in the frame, making it harder to open and close the sash. To remove any deposits — such as grease, oil or stains — that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner — such as Spray-n-Wash®, OxiClean® Fabric Cleaner or Resolve® Carpet Cleaner — to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the window’s movement. Pella Impervia single-hung windows have a removable lower sash for easy cleaning. If these windows are not properly repositioned after washing, they may be difficult to open and close. (See page 3.2 for detailed instructions on how to remove the lower sash for cleaning.) 7.1 Troubleshooting Double-hung windows The sash is hard to open and close. The sash will slide inside the frame. Over time, dirt and debris can get in the frame, making it harder to open and close the sash. To remove any deposits — such as grease, oil or stains — that may have come in contact with the weatherstrip, apply a small amount of concentrated fabric cleaner or carpet cleaner — such as Spray-n-Wash®, OxiClean® Fabric Cleaner or Resolve® Carpet Cleaner — to the weatherstrip. Scrub the cleaner into the weatherstrip with a toothbrush or similar applicator. Continue applying cleaner until the deposits are no longer visible. Rinse the weatherstrip with clean water, and dry with a paper towel. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the window’s movement. Pella® Impervia® double-hung windows tilt toward the interior of the home/building for cleaning. If these windows are not properly repositioned after washing, they may be difficult to open and close. Sliding patio doors The door latch does not always latch. The lock and strike are adjustable. Turn each of the four screws counterclockwise two turns. Adjust the strike up or down as necessary, and tighten the screws. The lock latch is adjustable to the left and right. The door does not slide smoothly. There are several possible causes. The track the door slides on may have debris on it, causing it to drag. If so, clean the track below the sliding panel. If this does not work, you may need to adjust the rollers to raise the door clear of the track. Adjust the rollers up or down to make sure the edge of the movable door is parallel to the side of the door frame. The adjustment holes are located on either side of the movable door, near the bottom. Remove the cap, and use a long-shaft Phillips screwdriver to adjust the rollers. Turn the adjustment screw clockwise to raise the end of the door, and turn counterclockwise to lower it. Replace the plastic caps. Once you adjust the door, you may need to adjust the lock strike up or down. See instructions above (under “The door latch does not always latch”). Sliding screen doors The screen door does not slide smoothly. The screen should move smoothly on its track. Apply a thin layer of paraffin or other dry lubricant (Teflon® Dry Lubricant or Gulf Wax®, available at most home improvement stores, works well) to the track if necessary. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the door’s movement. The screen rollers can be adjusted by turning the screws located on the top of the door. If the screen door is too tight at the top, turn the adjustment screws counterclockwise to lower the door. Level the screen door so the edge aligns with the lock jamb of the frame. Preventing condensation Understanding condensation. Moisture is present in all homes, but when it becomes excessive, homeowners need to take an active role in protecting their investment. Humidity and condensation. Humidity is a measure of the amount of water vapor in the air. Condensation is water that forms when warm, moist air hits a cooler surface. In homes, it might occur on surfaces such as windows, bathroom walls and cold-water pipes. When interior humidity levels are too high, in relation to cooler outdoor temperatures, condensation can form on the coldest surface in a room — often the glass in a window or door. While windows and doors do not cause condensation, they may be one of the first places it shows up. 7.2 Troubleshooting What causes condensation? Excess humidity is typically the cause of condensation. There are many sources for moisture in a home: showers, dishwashers, clothes washers and dryers, house plants, humans and pets, among others. In newly built homes, additional moisture may escape from building materials such as lumber, plaster and masonry for up to three heating seasons — even with proper airflow and temperature management. Older vs. newer homes. Condensation may be less of an issue in older homes if conditions allow for more air exchange between indoors and out, often from around aging, loose or poorly installed windows and doors. However, the tradeoff is higher energy bills. When replacement windows are properly installed and the airflow around the window decreases, condensation may form on the glass of the new windows. Newer homes, on the other hand, are more airtight and energy-efficient. Many have vapor barriers — plastic within the wall cavity blocking moisture passage in either direction. With tighter-fitting doors and windows, vapor barriers and increased insulation, energy costs are lower, but humidity levels must be monitored more closely. No matter when your home was built, the key is to strike the right balance when it comes to humidity levels. Air that’s too dry can cause furniture to dry out and crack, joints and studs to shrink and twist, and paint and plaster to crack. Excessive moisture in the home can cause paint to peel and insulation to deteriorate, and condensation on windows and doors can damage sills and trim. Measuring and controlling humidity. To determine how much humidity is present in your home, you can purchase a humidity gauge from a hardware store or home center. Invest in a quality unit for greater potential accuracy in assessing humidity levels, or consult an expert. Another way to monitor the interior humidity level is to watch your windows. When interior condensation begins to form, wipe it off. To reduce the humidity, open windows, run exhaust fans or dehumidifiers, or minimize sources of moisture. The University of Minnesota Laboratories provides a chart showing recommended relative humidity levels for the home. Maximum Recommended Humidity Levels Outside Temperature Inside Humidity 20º F to 40º F Not over 40% 10º F to 20º F Not over 35% 0º F to 10º F Not over 30% -10º F to 0º F Not over 25% -20º F to -10º F Not over 20% -20º F or below Not over 15% Based on engineering studies at 70º F conducted at the University of Minnesota Laboratories. Exterior condensation. Exterior condensation on windows occurs primarily in the morning when days are warm and humid, but nights are cool. Typically, it clears as the day warms. Exterior condensation can occur at any time, especially in warm, humid climates where interior temperatures are cooler than outdoor conditions. Exterior condensation means that windows are doing their job properly. However, if you spot excessive condensation on the inside of your windows, check your inside humidity — it may be a signal of potential problems if not addressed. Tips for wintertime moisture management. • Open window coverings — such as blinds, shades, drapes and curtains — during daylight hours to increase airflow over the glass. • Closely monitor the furnace humidifier and any other humidifying devices. • Be sure louvers and vents for the attic, basement and/or crawl space are open, adequately sized and cross-ventilated. • Run exhaust fans for the kitchen, bathroom and laundry rooms for longer periods. • Make sure exhaust fans vent directly outside, not into attics or crawl spaces. • Be sure chimneys are free and clear, so moisture in combustion gases can escape. • Follow the manufacturer’s instructions for venting gas appliances. In most cases, that will mean directing vents to the outside of the home. • Make sure your furnace is in proper working order and is serviced regularly. • Store firewood outside or in the garage — as wood dries, it gives off moisture. • Install energy-efficient windows, such as those that have earned the ENERGY STAR®. 7.3 Troubleshooting For more information on condensation in the home, consult the following: • Building Research Council at the School of Architecture, University of Illinois at Urbana-Champaign, http://brc.arch.uiuc.edu/f62.htm • Home Moisture Problems (Series 1437), published by the Oregon State University Extension Services, http://extension.oregonstate.edu/catalog • The University of Minnesota Laboratories, http://www.pella.com/maint/troubleshooting/preventing.asp?path=/maint.troubleshooting/preventing Eifs/synthetic stucco Pella® products should not be used in barrier wall systems that do not allow for proper management of moisture within the wall systems, such as Exterior Insulation Finish Systems (EIFS) (also known as synthetic stucco) or similar systems.
