AtTEK® is a favoured alternative to traditional dry or glycol systems in confined spaces and is changing the way wood buildings are designed.

AtTEK® eliminates the need for sprinklers and the associated risk of an unexpected flooding while the building is occupied.

AtTEK® Fire-Rated trusses are evaluated to meet code requirements for fire-resistant construction.

Specifically designed for harsh climates. AtTEK® binds to the surface of the wood to form a tough and durable coating, protecting truss members from potential fire threats.
