Need to know how to block sunlight heat from windows? Window blinds, shades, and panels all provide DIY window insulation, but also block light. That didn’t work for Beth Bryan in Alabama. She wanted natural light in her attic office, but it was also way too hot. “I could roast a chicken in here!” she said before getting an Indow Shade Grade Insert.
Beth’s attic office cooled by 16 degrees as soon as she added an Indow Shade Grade insert.
Beth works from home, where her office regularly gets up to 91 degrees. It’s well designed, but the west-facing window was no match for the Alabama summer sun. Her blog, Unskinny Boppy, chronicles her DIY home decorating and the pursuit of comfort. There, she shares how to keep heat out of windows and how once the insert was installed, there was an instant 16 degree temperature difference.

How to Keep Heat Out of Windows
Beth was intent on having access to natural light, but there are other window heat blocker options. More information can be found at the Department of Energy.
Window Blinds & Curtains – Blinds, fully closed are pretty effective at reducing summer heat. They are somewhat difficult to control and will let light in between the slats. Window curtains can reduce heat by 33% if multiple steps are taken: the curtains are medium-colored, have white-plastic backings, and remain closed.
Window Shades – Accordion-like insulated shades that can fold up to the top of your window frame. Usually two layers with air pockets in between to increase insulation. About 20% energy savings. Only insulating in the down, light-blocking position.
Window Film – Film adheres to your window glass and comes with many options: tinted, UV-blocking, Low-e, blackout. Their effectiveness depends on their transparency and orientation – less transparent and west/east-facing windows benefit more. This means, less light and loss of view.
Low-E Windows – Low-emissivity coatings reduce heat transference through windows up to 30% – 50%. If you’re interested in replacing your windows, know that low-e windows cost 10% – 15% and the coating lasts 10 – 15 years.
Window Inserts – Inserts or interior storm windows, block heat and UV-rays while allowing natural light to penetrate. Indow solar window inserts add 20% energy savings on average. They have the added bonus of blocking noise.
