Firestop Services

WISL is a full service Firestop contractor providing the newest fire-rating technologies and methods to protect industrial, commercial and institutional structures and their occupants. Failing to seal openings and joints is dangerous and can lead to the rapid spread of a fire. We specialize in the application of products specifically designed to close Through Penetrations (openings containing mechanical, electrical, security and communications services), Joints (between fire rated construction components), Perimeter Fire Barrier (slab edges and exterior wall cavities) and Blank Openings (openings in fire rated assemblies with no penetrating items).

Other systems such as Fireproofing and Intumescent Coatings provide protection to structural assemblies in order to improve their resistance to fire while decreasing the possibility of weakening, burning or melting under extreme heat. Cementitious and Fibrous spray applied fireproofing materials provide a formidable defense on steel beams, roof and floor assemblies, columns and concrete surfaces with fire ratings of up to 4 hours. Intumescent coatings are thin film decorative coatings designed to provide fire protection on these assemblies when they are exposed to view or where appearance is of primary importance.

I would like to express my gratitude for how much it was a pleasure working with your fire-stop team on the Golden Links Lodge in St. Vital. They conducted themselves with perfect professionalism. As a Superintendent, their knowledge and willingness to problem solve made managing the fire-stopping scope of work extremely easy.

I look forward to having an opportunity to work together with them again in the future.

You are lucky to have these guys under your banner.
