Heatlok Air Barrier System (ABS)

One source for a complete air barrier system.

Air Barriers work. For over 20 years, Demilec has supplied Heatlok insulation to millions of square feet of cavity wall applications throughout North America. Now we deliver the entire system.

The design community and construction teams have identified a “single source of supply” as the one thing missing in the air barrier industry today. Without the systems approach to material testing and installation, architects and general contractors are left with conflicting information, details that can’t be built and no single authority when it comes to membranes and spray foam insulation.

Demilec provides Heatlok ABS Membranes and auxiliary products, matched perfectly with Heatlok insulations to give you the confidence that a single source for insulation and air barrier materials, as well as factory trained installers and inspectors brings. Demilec also supports third party inspection programs through the Air Barrier Association of America (ABAA), if your specification calls for it.

At Demilec, Building Science Practitioners, Design Consultants, and Architectural Sales Specialists are with you every step of the journey from concept to close. With over 20 years’ experience in designing and installing insulated air barrier systems, Demilec can provide the right level of input and support needed to execute your design intent.
