CE Marked YEP 500 Roofing Felt Asphalt Shingles Underayment with Adhesive Band
Introduction:
Asphalt shingles underlayment is a layer under the exterior roof that has a primary function of working as the shield that protects the thermal insulation material and the building structure from the effects of the weather. The roof underlay acts as a condensation barrier, which leads condensate water away from the underlay, and thereby also from the insulation material.
