WeatherAll Insulation Underlayment

Insulfoam WeatherAll®

Insulating Underlayment

WeatherAll is available in a variety of types and formats providing the benefit of continuous insulation for added occupant comfort and energy efficiency, and a level surface for exterior cladding attachment improving the finished appearance.

Expanded polystyrene (EPS) and graphite polystyrene (GPS) with factory laminated facers feature stable R-value, moisture resistance, and labor savings options. Enhanced thermal performance, known as Effective R-value, can also be obtained by positioning the metallicized facer side toward a minimum of 0.75 in. of dead air space.*
