FAQ:

Q: Why choose radiantguard® Ultima-foil radiant barrier?

A: Our RadiantGUARD ® Ultima-foil radiant barrier reflects 97% of the radiant heat making them FAR SUPERIOR to any heat reflective paint and are much easier to install than a radiant barrier spray making the installation an easy DIY job.

Q: How does radiantguard Ultima work?

A: Traditional insulations like blown-in cellulose or fiberglass batt insulations only absorb and slow down the movement of heat. RadiantGUARD Ultima reflects 97% of the radiant heat away. Using two common properties of aluminum, HIGH reflectivity and LOW emissivity, RadiantGUARD radiant barriers are much more effective at blocking radiant heat.

Q: How do radiantguard radiant barriers work?

A: Using two common properties of aluminum, HIGH reflectivity and LOW emissivity, RadiantGUARD radiant barriers are much more effective at blocking radiant heat. When an air space exists between our Ultima radiant barrier and a heat source, it will REFLECT 97% of the heat back towards the heat source.

Q: Why choose Ultima-foil block?

A: Our Ultima-FOIL BLOCKS 97% making it better and less costly that paint. With the rise in popularity of radiant barrier insulation, there has been an influx of products marketed under the term radiant barrier paint that are designed to be sprayed on the underside of the roof decking in the attic.
