Questions & Answers

I currently have fiberglass insullation for my garage door. If this were mounted behind the fiberglass, against the garage door, would it improve it?

Asked by: Tom
you need the radiant barrier to have one side exposed to the air not trapped between the fiberglass and the door.

Hi, If this apply to rafters in attic, Is this barrier help for the cold weather? I mean keep house warm? Thanks
Asked by: dave
In an attic application you would want to use our radiant barrier (RB4812550) This product doesn’t offer any R value but it blocks 97% of the radiant heat in both directions. What this means is that in the summer it stop 97% of the suns energy from entering your home making it cooler in the summer. In the winter, when you have a heat source on, it blocks 97% of that energy from leaving your home making it warmer in the winter.

Will this product work under bench seats for radiator covers?

I want to build covers for my radiators in my very old house. Will this product effectively reflect the heat from the bottom of the bench seat into the room?
Asked by: Michelle
Just guessing...I wouldn't put it in contact with a heat source directly, but it's made to reflect 95% of the heat. I have it in my attic and notice a big cooling difference than before installation. Need ventillation -- it diverts the heat, not absorbs it, so the heat needs a place to go.

Can I use this on the attic floor which is also the ceiling below before I blow in my attic insulation? I'm refurbishing a 120 year old house and the ceiling boards have some gaps between the boards. I thought that I could install this product on the top of the ceiling boards and then blow in the attic insulation on top of it.
Asked by: Woody
You can do that, but it will NOT work as a radiant barrier. Radiant barriers need at least one face exposed to the air. Stapling this product to the rafters is the best way to use it. However, you can lay it across your attic floor AFTER you fill the joists with blown in insulation. Since this product is full of tiny holes (on purpose) any vapor entering the attic from below will pass through this product and exit the attic via the vents.
