Solar protection with VELFAC 200 DGU

Utilizing the free solar energy from the sun is necessary in low energy buildings to achieve the required energy performance.

However, too much of the sun’s heat is not always positive, especially on elevations oriented directly towards the sun, this can lead to overheating of a building making it uncomfortable for the occupants.

VELFAC offers various solar control glazing options which can regulate the intake of solar heating.
