High-Performance Quad R Insulation System

A contoured foam system precisely configured to fit the profile of any siding panel. It completely eliminates the problems associated with the void behind conventional hollow siding.

Independent research confirms that improved insulation and energy savings are a top priority with consumers these days. The most commonly used underlayments are only 1/4" thick, don't conform to the shape of the siding, and provide and "R" value of about 1. Fullback provides "R" values up to 4.0 depending on the product and profile of the siding itself. Homeowners report a 20% reduction in energy costs and a more comfortable living environment.
