Bituminous Systems - Airtech System

When to specify...

When a high quality bitumen system is required, but  site conditions prohibit the use of hot works, Airtech is an extremely effective torch-free bitumen membrane solution using hot air welding at the laps. It can be specified in both warm and cold roof design on all normal types of deck construction and is equally suited to either new build or refurbishment projects.  Our Airtech System meets current UK Building Regulations Part B for external fire protection.
