Spray Foam Insulation

Sprayed-in-place polyurethane foam is a proven performer for new construction that forms a continuous monolithic insulation and air barrier on the wall in a single step.

When introduced into Canada in the 1960s, sprayed-in-place polyurethane foam was found to be an effective insulation for demanding applications such as freezers, coolers, and controlled atmosphere storage.

Offering one of the highest R-values per inch of any insulation material available, spray foam insulation maintains economic competitiveness with rigid insulation and sheet good or mastic air/vapour barriers. When specified as the primary air barrier for the building, it can form a monolithic envelope around the structure, sealing angles and corners as it flows into gaps and cracks ensuring a tight seal around all penetrations. Spray foam insulation often eliminates the need for an additional vapour barrier since it controls the diffusion of moisture through the walls.

Great Northern actively supports specifying polyurethane foam to the architectural community. We employ trained professional installers, offer 3rd party warrantees, and adhere to the strict standards and specifications set-out in each manufacturer’s product guide.

Fireproofing

Great Northern Insulation is your one-source professional fireproofing contractor, offering cementitious, mineral fibre and intumescent fireproofing for structural beams, columns, steel decking and siding systems.

Passive fire protection can be defined as protective materials that prevent or delay the transfer of thermal energy to the structural steel. Spray-applied fire-resistive materials are commercially available in both cementitious formulations and as sprayed mineral fibre products. Both types of fireproofing protect the structural steel, providing valuable egress time for both occupants and firefighters in the event of a fire.

Great Northern is a qualified applicator of Grace Monokote, AD Fire Protection Systems and Carboline products. Monokote MK-6 and AD Type 5 spray-applied fireproofing for interior structural steel, with their proven in-place performance, are the most widely-used fireproofing products in the world.

In addition to being suitable for structural steel fireproofing, mineral fibre products also offer good thermal resistance (R-value), of particular importance for sidewall fire separations where up to a 2-hour rating is required. Typically, this would require 2.5” thickness minimum, and in many locations an R-value of 8-12 is required for the building. Only mineral fibre fireproofing products can attain this level of insulating value (with 2.5 - 3.75” applied thickness). In addition to fire protection and thermal insulation, these products also possess acoustic properties.

Intumescent fireproofing products are thin film decorative coatings designed for exposed applications where appearance is of primary importance. Finished off with an approved top coat these fireproofing products are increasingly seen as the solution to achieving fire resistance ratings for exposed structural steel.

At Great Northern, we can provide the technical expertise you require to assist you in the selection of a fireproofing product for any upcoming projects you may have.

Firestopping

 

Smoke, toxic gas and water are the major causes of building fire fatalities and equipment damage. A proper firestopping system is required by the National Building Code of Canada to ensure the integrity of fire rated assemblies is maintained where they are penetrated for various types of service equipment such as pipes, cables, conduits, cable trays, ducts, or where there is a construction joint, such as a curtain wall design, gap or space.

In the design of institutional buildings such as schools or hospitals, concern for human safety dictates the use of effective penetration seals. Industrial facilities on the other hand require protection from shutdowns and business interruptions, whose cost may far exceed the actual equipment losses caused by a fire.

At Great Northern, our professionals can provide the technical expertise you require to assist you in the selection of a firestopping product to meet your needs for any projects you may have.
