Intelligent Membranes develops high-performance liquid-applied coating systems designed to improve air barrier performance, control moisture, and protect the building envelope.
Our products are used across residential, commercial, and retrofit construction, supporting energy-efficient, durable, and code-compliant buildings.
Our core solutions include interior and exterior air barrier coatings, waterproofing systems, and vapor control layers designed for compatibility across multiple substrates.
Compared to traditional sheet membranes, our liquid-applied systems simplify detailing, reduce installation complexity, and ensure continuity across complex junctions and penetrations.
Tested and certified, our systems support high-performance building design, including projects targeting energy efficiency and long-term durability.
