Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.
How much does a radiant barrier help?
As mentioned above, a radiant barrier can improve home energy efficiency. In fact, according to Energy.Gov, the radiant barrier can improve energy efficiency of about 5%-10%. This means your A/C bill could reduce by about 5%-10%.

In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.
Can radiant barrier cause mold?
When radiant barriers develop moisture problems, they can impact the efficiency of heat repellency. In addition, unchecked moisture can drop down onto other surfaces in the attic, causing water damage and mold. In order to prevent moisture issues, it’s imperative to use perforated radiant barriers.

Does radiant barrier help in winter?
How do radiant barriers work in winter? Radiant barriers, however, also help prevent winter heat loss. … In the winter, most of the heat that escapes through your ceiling and roof is radiant heat. A properly installed radiant barrier can reflect that heat back into your home before it escapes out of the home.
Does radiant barrier attract lightning?
Radiant barrier sheathing (RBS) is an extremely efficient ignition source for structure fires and it exhibits some most unusual (even strange) behavior patterns. A roof constructed with RBS material appears to actually attract lightning.
Can you put insulation over radiant barrier?
This can make your air conditioner run later into the night. If you have marginal attic insulation, installing a radiant barrier will make what insulation you already have even more effective. By combining good attic insulation and radiant barrier, you will get the best of both properties.
Which way should radiant barrier face?
Research by the Florida Solar Energy Center (FSEC) found that radiant barriers work best when installed with foil-face down (towards the building interior) and applied under the roof sheathing.
Can I install radiant barrier under shingles?
You can install the radiant barrier foil below the raised shingles either on top or below the battens. … The easiest and best way is to run the foil out over the roofing felt, tack it down and then install the battens followed by shingles or metal roofing.
