More Than Just Insulation

SGI is an all-in-one product that provides insulation and a radon, air and vapor barrier. SGI is code compliant.

Available in Rolls or Sheets

SGI rolls are 11/16″ thick x 4′ wide x 48′ long (192 sq ft), and 4′ x 8′ sheets.

All SGI products have varying thicknesses and densities. The effective R-value performance is from R-5 to R-30.

Fast and Hassle-Free Installation

SGI is quicker and easier to install than the usual below grade insulation products and poly. This is because 1 roll of SGI is equal to 6 sheets of traditional foam board insulation.
