Attic Insulation & Radiant Barrier Benefit In Cold Climates
AtticFoil.com – How Attic Insulation & Radiant Barrier Work Together in Cold Climates This video shows the benefits of combining radiant barrier attic foil with attic insulation. Installing radiant barrier attic foil along with good attic insulation will help to make your home more comfortable and energy efficient. A radiant barrier will reduce radiant heat loss and reduce air flow in the insulation which reduces the R-Value of the attic insulation.

I would put in additional attic insulation and radiant barrier. Think of insulation as big jacket. Radiant barrier and insulation work together, but 5-6 inches is on the low side.
My husband and I have an older home with about 5-6 inches of insulation in my home. We talked about adding insulation as a way to make our home more energy efficient. So if we install radiant barrier foil, do you recommend adding more insulation before the radiant barrier foil or is this enough?
If you are going to lay the foil over the insulation it is VERY important to use perforated radiant barrier Attic Foil. Perforated foil has tiny pinholes about every half inch that allow moisture in it’s vapor form to pass through so moisture will not get trapped. It is also important to seal up holes in the ceiling that will allow warm-moist air to escape from the home into the attic.
Does the radiant barrier allow moisture to go through? I am concerned with trapping moisture.
@AtticFoil Thanks, that was very helpful. It’s cold this winter and I think this will help my home be more consistent.
Taping the seams is not required. You have a couple of options. The best and easiest way is to jut use a 3-5″ piece every few feet to “tack” the pieces together. If you have a large open area, you can lay out 2 or 3 pieces of foil side by side and tape the seams together to make an 8 or 12 foot wide piece. Then, roll up the foil like a rug and take into the attic and just roll it out. You can cover a lot of area fast this way.
OK, this makes a lot of sense to me. But I’m unclear on if I need tape the seams or not. Please help!
