Double glazing does little to stop the heat, I think you have already fitted the best protection having shutters on the windows, something I am going to look at doing in the future, not straightforward due to way windows are framed at my place - I am waiting for divine inspiration to get a brilliant idea to resolve problem.![]()
We have window tint - not convinced it does a lot? stops anyone looking in during the day, but where I live there is no one to look in anyway, not great for the bird life, must confuse them as they fly into windows at times, they will also sit and look at their reflection and peck at the glass, have to scare them away as quite noisy and irritating.
