Dimenzije
maksimalne dimenzije stakla 321x600 cm
Dostupne debljine (ovisno o vrsti stakla):
3,4,5,6,8,10,12,15,19, 25 mm , najčešće
4,6,8,10 mm
Mogućnost prerade: rezanje, posebni
oblici, brušenje rubova, kaljenje,
laminiranje

dimenzije
Maksimalnedimenzije za:
kaljenje, najčešće 240x420 cm
lokalno laminiranje najčešće 200x380 cm
Na zahtjev veća kaljenja stakla mogu biti
isporučena, no trošak može biti značajan.

težina
Gustoća stakla ρ =2500kg/m3
Npr.
4mm - 1 m2=> 10 kg
10 mm - 1 m2=> 25 kg
IZO 4000x2000mm, kompozicija 10-16-88.2 => 520 kg !!
akvarij 2000x1000x1000 mm, kompozicija 10.10.2
prazan (samo staklo) = 400 kg
Bez vode (without ‘metal structure!)= 2400 kg

Što znači solarna kontrola
Solarna kontrola = limitira prolaz topline
kroz staklo kako bi se smanjio efekat
staklenika. SF=20—45%

sa nanosom (pirolitički prmaz ili
magnetron) itd..

money, money, money..
Energy from Sun: 1000 W/ m2 (with normal clouds etc)
Energy which is “touching” vertical window: 750 W.
hypothesis: 100 m2 of windows or façade. Cost 1 kWh= 0.42 RON. HVAC working 30 days* 6 hours a day=
total 180 hours
•SF= 0.64 ( clear glass + lowE) => Heat = 750*0.64= 480 Wh/ m2 of window.
For 100 m2 facade, monthly => heat: 480x100x180= 8640 KWh.
•SF= 0.29 (Sunergy Green 6mm+ lowE) => Heat 750*0.29= 217,5 Wh/ m2 of window.
For 100 m2 facade, monthly => heat: 217,5x100x180= 3915KW.
Electricity COST if SF=0,64=>8640x0,42= 3628 RON= 863 EURO
Electricity COST if SF=0,29=>3915x0,42= 1644 RON = 391 EURO
For only 100 m2 of façade, monthly, there is a difference in cost of 472 Euro!!
In only 3 months of summer, the slightly higher cost of Sunergy Green will be paid back!
The smaller SF, the better , because cost of electricity will be smaller but also cost of HVAC (cooler or chiller)
will be smaller. BUT DO NOT FORGET PLEASE about Light Transmission LT (or selectivity) , otherwise better
to replace windows with bricks and you will have SF= 0 (zero).
CONCLUSION? Look for low Solar Factor SF, especially for South oriented facades, and search for highest
selectivity (S=LT/SF). Stopray Lime= the best solution. Sunergy Green= very smart solution
Planibel Green= very good solution for E, W and N facades
