Low-E glazing is designed to keep heat in during the winter creating an overheating problem in the summer.
The charts below show the difference that Microlouvre can make when used in combination with Low E glazing.
Summer Solar Heat Gain of Low-E Glazing
Solar Heat Gain of Low-E Glazing with Microlouvre*
gv = 0.59: Solar factor of standard glazing (C), low-emission 4/16/4 double glazing with Argon (U value = 1.2 W/m²K).
Comfort classiﬁcation according to EN 14501 standard:
0= very little effect 1= little effect 2= moderate effect 3= good effect 4= very good effect
