Sikagard® AWB 660

Sikagard® AWB 660 is a high-performance, fluid-applied air and water-resistive barrier (AWB) engineered to enhance the durability and energy efficiency of building envelopes. Designed for above-grade wall applications, it provides seamless waterproofing while allowing vapor permeability, preventing trapped moisture that could lead to mold or structural damage.

This one-component, water-based formula ensures superior adhesion to various substrates, including poured concrete, unit masonry, gypsum sheathing, cement board, OSB, plywood, EIFS, and stucco. Its exceptional nail sealability, abrasion resistance, and low VOC content make it a reliable and eco-friendly choice for commercial and residential construction.
