More comfortable summers

Sky light blinds


Q: Will solar blinds really keep my home cooler in summer? We have two large bay windows and I was looking at installing some Krumpers solar blinds or perhaps some awnings. I’m skeptical about the blinds since they still let heat inside the glass.

A: Your plan is a great way to reduce heat buildup during summer. And though I don’t have any personal experience with the blinds you’re thinking of, I expect they’ll help quite a bit. The research I’ve looked at with the Krumpers product impresses me.

Your concern about heat still getting between the glass and the blinds probably won’t turn out to be an issue. The light colour of solar blinds will reflect energy back out again through the glass, but you don’t necessarily need to go ahead on mere “blind” faith. Before you commit to buying, try simulating blinds by putting a sheet over your window temporarily during sunny weather. I think you’ll find it makes quite a difference, and proper blinds will make even more of a difference.

Although most people don’t realise it, openable skylights with blinds offer another option for keeping houses cooler during the summer. Even homes with central air conditioning often still have upper rooms that are way too hot in the summer. A few operable skylights left open even an inch or two allow hot air to escape outside, enabling the air conditioner to do its job upstairs. The best solar skylights don’t require wiring and they can open and close electrically, either on schedule or manually. They also close automatically when the first drops of rain hit.
