Super R Plus® H.D.

Radiant Barrier

Super R Plus Hd Product Main

Highlights

For the projects that deserve the very best. This construction grade and industrial grade Radiant Barrier reflective insulation is the thickest and strongest Radiant Barrier product on the market. It can be used in the same applications as our renowned Super R Plus® with the addition of extra strength and rigidity. The increased structural strength of this material makes it the easiest to install.

Available in 500 and 1,000 sq ft rolls or custom lengths beyond.

Comes in perforated 4' widths.

Frequently Asked Questions

The “R” value depends on the number and size of the airspaces surrounding the Radiant Barrier and on the direction of the heat flow. Since Radiant Barrier is usually installed on top of existing mass insulation, its R-value is a moot point. It is Radiant Barrier’s ability to reflect heat that makes it such an energy saver.

The Florida Solar Energy Center at Cape Canaveral has tested radiant barriers in both small-scale laboratory and full-scale building models. Their results indicate that radiant barriers provide significant resistance to heat transfer. Current tests conducted by the Tennessee Valley Authority and the University of Mississippi support the findings of the Florida Solar Energy Center. Northeastern Illinois University conducted winter tests in residential and commercial structures using infra-red thermograph photography. The photos showed significant resistance to heat transfer over the regular insulation.

This very issue has been studied by research institutes. Most attics don’t accumulate enough dust to affect Radiant Barrier’s ability to save energy costs. Thousands of homes and structures have had Radiant Barrier installed for as long as ten years or more with no significant accumulation.

No. The foil on the fiberglass is in direct contact with the attic floor. Aluminum foil becomes more conductive when in contact with a solid surface. The air space facing the reflective surface is of primary importance.

Radiant Barrier can be laid over your present insulation like a blanket or stapled under your rafters or crawl space.
