SOL-R-Wall, composed of paper backing and foil facing, is a uniquely efficient wall insulation providing an excellent option those needing formaldehyde-free insulation.

  • Overview


    Insulation is a perfect extension of our full line of formaldehyde-free insulation. When installed in a concrete or masonry wall, reflective foil insulation provides resistance to solar heat gain in hot, sunny climates. Which means homeowners save on cooling costs in the summer.


    The secret is in the pleats. When SOL-R-Wall Insulation is properly installed, the reflectivity and low emissivity of the aluminum facing help block radiant energy so overall heat transfer is reduced. The specially engineered pleats expand to form air pockets between the layers of paper and aluminum. These spaces restrict air movement, thereby reducing convection and thwarting heat transfer.

  • Specifications


    Insulation has an inside layer made of aluminum foil. The outer layer is natural kraft paper. When installed on 1" x 2" furring strips spaced 16" to 24" on center, a second reflective air space is formed.


    SOL-R-WALL Insulation is packaged in lightweight rolls for easy carrying.


    For additional installation information, please see ASTM C-727, "Standard Practice for Installation and use of SOL-R-WALL Insulation in Building Constructions".

Thermal Efficiency

When properly installed, the uniquely designed Sol-R-Wall insulation provides an effective resistance to heat transfer with a minimum R Value of 4.0.

Conforming Fit

Width expanded construction allows a perfect fit for furred out walls 16" to 24" as well as irregularly sized wall cavities.

Moisture Control

Sol-R-Wall's facing design includes micro-perforations that allow the product to breathe and resist moisture build-up.

Concrete and Masonry Applications

SOL-R-Wall Concrete and Masonry Applications

SOL-R-Wall can help improve productivity, comfort and lower energy costs for your commercial buildings by addressing all three modes of heat transfer; radiation, conduction and convection. First generation reflective insulations utilized packaging materials such as bubble or foams to create the core. These products worked well but limitations relating to where they could be used due to the safety concerns relating to fire issues. These products are mostly vapor barriers so use in the areas such attics and kneewalls is not recommended as moisture problems could be created.

Non-Corrosive Materials

SOL-R-Wall was designed with agricultural buildings in mind. SOL-R-Wall is lightweight for easy installation and is rodent and bird resistant. Because SOL-R-Wall addresses radiant heat loss and gains in buildings, it can help increase productivity, and reduce mortality. SOL-R-Wall is available in either Foil Faced or White Faced to enhance your building's interior.
