So my radiant heat barrier arrived & was (mostly) installed yesterday! [View all]

Love it!

Ceiling temp at ductless indoor unit is down from 85F to 75F today! Yaaaaaay! Love it!

Cost for 1k sq ft roll ~$130 for a high quality foil. It blocks 97% of radiant heat through roof. No clud what attic temp is today, but it was 187F yesterday!

If your AC is struggling to keep up, or if you want to lower energy use & AC costs, you might want to consider this.

Easy install. All you need is a staple gun, staples & a regular pair of (Dollar Tree!) Scissors.

Install must leave an air barrier between roof & foil, so it looks kind of billowy. But I don't live in the attic, so I couldn't care less.
