Since buying their house, our client never really knew of a cost-effective solution to reduce the heat in their bedroom, and this even in the winter. It could get as high as 26C during the day in their master bedroom and this was becoming unbearable. They had considered changing their windows and certainly did not want to add darkening film. Following the application of SketchNanoGard, the room has become clearly more comfortable, staying around the thermostat’s set-point: 21C. They’ve also noticed the rooms are feel less cold once the sun goes down. Another satisfied client.
