The goal of fireproofing is to protect, control or delay the combustion of flammable materials during a fire.

What is fireproofing?

In residential and commercial applications, fireproofing is used mainly to cover polyurethane spray foam or any other form of insulation or polystyrene and thus provide a fire resistance of 10 minutes as required by the National Building Code. The fireproofing material will be applied mainly on walls and in crawl spaces, delaying the combustion of flammable materials during a fire.


How can fireproofing protect my property?

For example, a structure made of steel which is not protected by fireproofing can lose at least half of its resistance when exposed to extreme heat caused by a fire. This could cause a collapse of the structure and therefore the entire building. Proper fireproofing executed by a team of experts will protect the structural integrity of the building and limit the damages.


The advantages of fire insulation

There are many advantages to fire insulation. In addition to limiting the damage caused to a home during a fire, it can have a positive impact on a homeowner's home insurance costs. Fire insulation also acts as a thermal insulator while providing some soundproofing, making it an attractive and profitable investment over the long term. This type of insulation is also highly durable.

Considered to be an innovative product and one of the more efficient ones on the market, CAFCO 300 offers the best fire resistance as a function of thickness out of all types of plaster-based flame retardant agglomerate on the market. Ideal for steel structures, ceilings and walls, it can also be used on concrete. This product is mainly used in commercial construction projects.


CAFCO 400 is designed for locations that experience greater wear due to movement required for maintenance such as, for example, machining spaces. This medium density Portland1 cement based flame retardant provides the same fire resistance per thickness as CAFCO 300. It provides protection in any environment where a medium density material is required.

CAFCO Blaze-Shield II

CAFCO Blaze-Shield II is the only inorganic product that can be used on the outside of a building during its construction under extreme weather conditions. Furthermore, in addition to its efficiency of application, it provides thermal and acoustic properties. Made of Portland1 cement, it is applied directly on the coating of steel beams and columns or on concrete surfaces that must be concealed during an extended construction period. This product has a high content of recycled building materials and offers excellent durability. Since it requires no pre-mixing, the labor costs for installation are reduced, making Blaze-Shield II the most economical flame retardant in its class.

Monokote Z-3306

Monokote Z-3306 is a Portland1 cement based thermal barrier coating designed to be applied on polyurethane and polystyrene foams. Durable and resistant, it provides protection against heat and fire with a delay of 10 minutes. Furthermore, it meets all the requirements specified by building codes and insurance companies.

All these products can also act as thermal insulators. This is an advantage particularly when installed under the roof because they reduce heat loss, thereby increasing the R value, which may thus allow a reduction of roof insulation.

1 Portland cements are hydraulic binders. When adding paste (cement, air and water) with aggregates (sand and gravel, crushed stone or other granular material), it acts as a glue and binds together to form aggregates like stone or concrete.
