Bottom Operated Std. Polyurethane roof window Centre-pivot - GLU 0051B

Heat insulation
The low energy glazing provides reduced heat loss through the window and enhanced indoor comfort.Uw = 1.3

Solar gain
In the wintertime, the heat from the sun entering through the windows is a usable solar gain.g = 0.64

Solar protection
In warm climates and in rooms with large window areas, a sun protective coating provides a better indoor climate during summer periods.★★☆

Sound insulation
A combination of laminated glass and optimal glass thickness provides better sound insulation against noise from outside (traffic, playgrounds, etc). RwdB = 29(-1;-3)

Energy balance
The energy balance represents the ability of the roof window to utilise the passive solar gain and keep in the heat during winter. It also represents the ability to protect against the risk of overheating during summer.

Outside strength
Toughened outer glass makes your glazing more resistant to hail, heavy wind and snow loads.
