With top-of-the-line heat protection and blackout capabilities, the VELUX anti-heat blackout shutter enables you to stay cool in the summer for a good sleep night and day. Anti-heat blackout shutters block the suns rays before they reach your window and heat up your indoor room. This provides superior heat protection compared to interior blinds, resulting in a reduction of indoor temperature by up to 5 degrees*. The result? Maintain the perfect temperature indoors on hot days and sleep comfortably during the summer.
