The one question I probably get asked most often is: “What all do I need to know to install AtticFoil Radiant Barrier Foil Insulation?”
The big concept is you’re trying to get a piece of radiant barrier foil between the roof and the insulation; the goal for heat rejection in the summer being to keep attic insulation cooler by preventing it from absorbing radiant heat from the roof. In this video I will explain it as quickly and concisely as I can.
So, in summary here is what you need to focus on:
- Get the foil between the insulation and the roof line.
- Staple it up across the rafters; it doesn’t have to be smooth or pretty. You can use 48″ wide radiant barrier foil to work horizontally, or 26″ wide radiant barrier foil to work vertically.
- The staples are standard size – 1/4 or 5/16th size work fine.
- Cover as much as possible; the more space you can cover, the better your results. Even partial coverage works!
- Allow ventilation a free path to flow in to the attic from down low at the soffits and escape the attic up high, near the ridge (via a ridge vent, gable vent, attic fan, etc.).
