How We Install Radiant Barrier
An adequately installed radiant barrier is stapled to the rafters of your attic. This method leaves a 6-8 inch air barrier, allowing the foto il breathe and reducing the chance of any radiant heat being conducted into your attic! Radiant barrier foil LOVES air…let it breathe!
As hot air rises, the foil allows it to travel from your soffit vents up to the top of your attic, which can be exhausted through your roof vents. Whatever ventilation system you may have: passive, turbine fans, ridge vents, electric fans, or solar vents…radiant barrier can be engineered to allow proper airflow and reduce your attic temperatures dramatically!
On the other hand, anything applied directly to your roof deck will not breathe and will most certainly conduct radiant heat into your attic space. It’s essential to consider the different product types out there and ensure that you are getting FOIL stapled to your rafters!
Why We Do Not Recommend Installing Radiant Barrier On The Floor
Radiant barrier installed on the floor is mostly a thing of the past…but we still see it occasionally. In the northern states, it’s still popular, but remember, a radiant barrier is designed to stop heat from entering your attic at the source: THE ROOF!
Moisture can be trapped under a radiant barrier installed on the floor, insulation underneath can be damaged, and it doesn’t work effectively. Make sure you are installing products to do what they are designed to do: radiant barrier stops heat from entering the attic, and insulation on the floor of your attic will keep your conditioned air in your living space.
What To Do If Your Already Have Radiant Barrier Installed On The Floor
Some of the hottest attics we’ve ever been in already have radiant barriers on the floor. They called us out, saying, “Hey, we got a barrier, but it didn’t work!” And they were right. It didn’t work because it wasn’t installed properly! By removing foil off the attic floor and adequately installing it on the roof rafters, we will change your mind about radiant barriers forever!
