What Is The Best Insulation For My Home?

The best insulation will protect against moisture, heat, and chill. Additionally, the best insulation lasts long, is easy to install, and requires little to no maintenance. Fortunately, the Insul-Barrier Walls Insulation System is an insulated vapor barrier perfect for your crawl space, basement, and attic. Our product features reflective technology and powerful insulating layers which deliver the best thermal performance. This performance keeps unwanted moisture and temperatures from invading your living or working space.

About The Insul-Barrier Walls Insulation System

There are five layers to the Insul-Barrier. These layers are designed for fluffing. This fluffing aids installation by ensuring adequate airspace among the layers. Furthermore, there are two outside Polyethylene skins (outside layers). These skins are designed to protect the inside of your product from damage and to create an effective moisture barrier

Lastly, one skin is reflective white, and the other is reflective silver. Within the reflective silver, Polyethylen skin is a high-density bubble pack, followed by two layers of high-density closed-cell foam. Then, the protective reflective white surface is the last layer.

The top and bottom are hemmed while the bulk of the “blanket” is designed to separate for airspace.

Our product is made as a single 4’ x 25’ panel, factory-installed grommets space along the top hem allow easy installation.

Furthermore, Our product provides water vapor protection as well as energy efficiency. The Insul-Barrier rolls are easy to handle and maneuver in tight spaces. This maneuverability makes our multi-layer “blanket” wall insulation system perfect for crawl spaces and frost line coverage (top 4’) in basements.

What is a good R-value for exterior walls?

R-Value measures the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power. Our product is perfect for basements and crawl spaces because the R-12 rating prevents moisture trapping. This prevention lowers mold while increasing air quality. The Insul-Barrier Walls Insulation System provides enough room for your room to breathe while avoiding the accumulation of water vapors, heat, and chill.

Improve Your Home’s Efficiency With The Insul-Barrier Walls Insulation System

Installing insulation is a tricky job. You can over-insulate your home by trapping moisture in your walls. However, our product’s manual can help walk you through the best ways of insulating your home.

Order the Insul-Barrier and provide your home with energy efficiency, cleaner air, and water protection.
