Why is it Vital to Fireproof Commercial and Residential Buildings?

The fireproofing process saves lives by preventing or delaying the combustion of flammable materials. It can also allow certain materials, such as steel, to retain their physical properties during a fire to give the occupants time to leave the premises safely. Our fireproofing products are designed to protect, reduce, control or delay the combustion of flammable materials. Our technicians proceed to a careful application to treat combustible materials.

What Materials and Structures are Most at Risk?

Plastics and plastic foams, for example, are extremely combustible. They must be fireproofed so that they do not cause a fire or accelerate the spread of fire. Buildings with a steel structure must be protected against fire, because heat causes the steel to lose all its strength. In case of fire, there is a high risk that the building will collapse. By fireproofing the steel structure, it will be able to resist heat longer and keep its physical characteristics.

There are a multitude of specialized fireproofing products that can protect specific materials in order to comply with the standards required by the Quebec Building Code and insurance companies.
