Our flagship product for weatherizing and retrofitting existing buildings or new construction. This insulation provides consistent thermal resistance against outdoor air and helps maintain indoor temperatures. Greater air resistance means better temperature control. This premium product is BIBS approved. Made with recycled glass, it’s the smarter way to stand up to the cold.

Product Features
Quality Design
Engineered with a class A fire rating, this insulation is noncombustible. It can provide good air flow resistance and improved sound control versus uninsulated areas.
Easy Install & Handling
Installs clean and easy. Installers can spend less time installing as it requires fewer bags, compared to cellulose material — which can make the job more efficient.
Thermal Performance
Excellent thermal properties help reduce the operating costs of heating and air conditioning. Fills all gaps and voids in wall cavities, helping to meet required building codes.

Coverage and installation data were determined using a Volu-Matic® III blowing machine in third gear with 13" gate opening, 2.5–3.0 PSI air pressure, 150' of 3" diameter internally-corrugated hose. Volu-Matic III is a registered trademark of CertainTeed Corporation.
*“R” means resistance to heat flow. The higher the R-value, the greater the insulating power. To get the marked R-value, it is essential that this insulation be installed properly. If you do it yourself, get instructions and follow them carefully. Instructions do not come with this package.
**Based on Third Party 10-year settling study, the predicted settlement over a 20-year period would be 1 percent or less. This amount of settling is thermally insignificant. Therefore, the installed and settled thicknesses are effectively the same.
