How can I insulate a window to keep a bedroom cooler?
We recently moved to a fairly new house built in 2026, my daughters room is the hottest room in the house which sits over the garage and faces North/East. In the summer the outer wall/window gets the morning sun and most of the day and it gets really hot in there. The window is fairly large and double paned. We've tried using that film that's supposed to block out heat but it didn't really help.
