ADESO is a revolutionary self-adhered technology offered by Polyglass on many of our APP and SBS membranes. Using a combination of patented features, ADESO technology enables the manufacture of dual-compound membranes with a true APP or SBS formulation on the top weathering side and a powerful self-adhered formulation on the bottom layer, providing superior adhesion without the need for additional adhesives.

No other underlayment on the market is made with this unique formulation, and none can surpass its level of protection.

All Polyglass underlayment products are self-adhered using our patented ADESO technology, coming in easy-application peel-and-stick rolls.

An underlayment “lays under” the main components of a roofing system to provide an extra layer of waterproofing protection. Underlayments are typically made of rubberized asphalt, asphalt-saturated felt, or synthetic materials. The underlayment is attached directly to the roof deck and is designed so other roofing materials can be installed directly on top of it.
