The best way to insulate your home from heat is to stop the sun your glass/windows from heating up in the first place.
Sometimes, internal blinds are not the best option for insulating your home from heat. Once heat has penetrated the glass of your windows, the internal window coverings are trapping the heat between the glass and the blind. Therefore the heat is already in the room making the room very hot, particularly on the western side of the home.
The best way to stop the heat from penetrating the glass is by covering the window on the outside with awnings or shutters. There are plenty of awning styles available, from fixed to retractable, manual and motorised, and plenty of fashionable fabrics and colours. Shutters can also be used much like a privacy screen, and the blades can be fixed or moveable.
External Solutions don't just insulate your home from heat! They can give you privacy while allowing your breezes to float through your home. They also add character to your home. With so many styles and colours available, your home can look like it's been completely renovated.
