We have a half bath in our house(built 2017) that was always cold. I've checked the insulation, wi dows seals, and even upgraded the heat run fron a 4" to a 5". Nothing seamed to improve the temperature in the room. I i stalled this damper i. The ventilation fan and within minutes the room was as warm as the rest of the house. Its currently -30°c here and the room is warm. 10/10 will install in every bathroom from now on.

Ce n'est pas des volets qui s'ouvre ou se ferme. C'est une simple membrane,qui se lève et se rabaisse.
