How to Keep Harmful Sunlight from Coming Through Windows
Ask Danny, Doors and Windows, Green Home by Danny Lipford
I have several windows that receive a lot of sun in the afternoon. What’s the best way to keep the heat and sunlight out while still being able to see outside? -Joan
Hi Joan,
UV rays and solar heat from windows can damage furniture and fabrics and increase air conditioning bills. To prevent this from happening, consider installing special window film on the inside of your glass that blocks UV and solar heat. Window film comes in various tints, just be sure the one you get blocks both UV rays and heat.
DIY-friendly window film is available at home centers, or you can have it professionally installed. If your windows have double pane glass, check with the window manufacturer first to be sure installing window film won’t damage the glass or void your warrenty.
Another option is to replace your existing windows with insulated, Low-E glass. When purchasing replacement windows, choose the recommended glass and Low-E coating for your particular climate.
Good luck with your project,
