What Is Radiant Barrier Insulation?
If you’ve ever been up on a roof you know how hot it gets. Attics also get hot, especially here in the Houston area. Insulation keeps that heat (or cold) from penetrating your living space.
A radiant barrier reflects radiant heat. Radiant heat is the heat that transfers from one side of something to another. For instance, your roof is baking in the summer sun. Those shingles, felt paper, and roof sheathing radiate heat downward into the attic. If you were to go into the attic and press your palm against the wood of the ceiling, it would be warm to the touch on a hot summer day.
The hotter that attic gets, the more heat is trapped in your home and without proper insulation, it will begin to enter your living spaces.
But when a radiant barrier is placed between the inside roofing materials and the floor insulation, less heat enters the attic. With a radiant barrier, a sizeable portion of the radiant heat is reflected back toward the roof and very little of it is emitted downwards.
Attic temps stay cooler and the insulation is more effective at its job.
In the past, a traditional shingle roof called for the radiant barriers to be stapled to the under part of the roof rafters. But that was only as effective as the stapling and sealing of that crew.
At Holden Energy Solutions, we use a liquid that looks like a white, chalky paint but the HeatBloc-Ultra has the lowest (best) emissivity rating of any liquid product on the market today.
What Is Emissivity and Why Should It Matter to Homeowners?
All materials give off or radiate heat when sunlight hits them, some more than others. Emissivity is the number used to express how much heat a surface radiates. The higher the emissivity number, the more heat it’s capable of radiating.
Radiant barriers have a low emissivity. Their purpose is to block radiant heat. But even though they all have a low emissivity, they don’t all have the same emissivity. HeatBloc Ultra, the product we use, has the lowest rating of any liquid barrier. Which if you’re trying to keep your attic cool and your cooling bills down, is just what you’re looking for.
