What is the difference between RadiantGUARD® Standard, Premium and Ultima radiant barrier??
The primary differences in RadiantGUARD® radiant barriers are in the weights and the puncture and tear resistance characteristics. Ultima-NXTgen is our most durable and industrialized radiant barrier with an extremely high puncture and tear resistance factor. It is ideal stapled to the underside of roof rafters and stapled to wall studs as a house wrap. Ultima perforated can also be laid over the attic floor. Premium is our next durable version and is the most versatile of our radiant barriers ideal for both stapling to attic rafters and laying over the attic floor. It weighs almost 1/2 the weight of Ultima making Premium very easy to handle. While it’s not as puncture and tear resistant as Ultima, which is almost impossible to tear by hand, Premium is reinforced with a durability scrim layer giving it resistance to tearing. All RadiantGUARD® radiant barrier products are high quality, double-sided, tear and puncture resistant radiant barrier products of higher quality than many
