We only use the best materials during manufacturing in order to guarantee an optimal blackout effect. This makes the three-layered Oeko-Tex® fabric especially dirt-repellent. The fabric is made out of a polyester layer and a lightproof intermediate layer. The back is formed from a special coating made of aluminium. This high quality coating protects any room from light coming in from outside and also improves insulation. With a VELUX blackout blind, you can not only darken your living rooms with ease, but you can also avoid losing heat through the window in the winter and thereby improve the energy balance of your house. 

VELUX insulation collar for use with EDL, EDP, EDW flashings. Also includes BFX underfelt collar for additional weathertightness. Reduces heat loss and eliminates cold bridges.
