Radiant Heat Barrier Paint Vs Foil

For the record both the radiant barrier spray paint and the radiant barrier foil will reflect i e.

Radiant heat barrier paint vs foil.

A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates. However the fine print exists when the best available radiant barrier paint can only reflect about 75 of the radiant heat transfer. This action increases energy efficiency and lowers the associated cooling energy costs. Has minimum emissivity properties of 05.

Paint radiant barriers use aluminum to minimize solar gains by reflecting the sun s rays back away from the air conditioned building. We take a look at how radiant barriers work the different types of radiant barriers and some of the. Which type of radiant barrier is best. And that means quite simply radiant barrier foil is a far more efficient option than spray on coatings.
