What is sprayed insealation?

• a polyurethane foam that:
• does not use formaldehyde, CFC's or HCFC's
• meets off-gassing requirements of CGSB 51..23 92 for new residential construction (no toxic or carcinogenic products are detected)
• a complete system that:
• insulates
• seals and controls air leakage (including airspaces around electrical outlets, faceplates, at baseboards and window/door framing) and sound
• a one step insulation and air barrier system

Is the same foam used in all types of applications?

• open celled foam is used in housing applications
• closed cell foam is used in floatation and freezer applications

Where can sprayed insulation be used?

• new construction
• in ground heating pipes
• outside walls, ceilings, attics
• spas
• fishfloats, floating docks and boats
• hot tubs
• freezers, refrigerator trucks

What are the advantages?

• a lifetime transferrable warranty
• an inert, chemically and physically stable material that will not settle, shrink or sag after time (thus retaining its R-value)
• heating and cooling costs are typically reduced by 30 to 50% and allow for the use of smaller, less expensive heating and cooling equipment

• eliminates energy robbing air leakage and the associated problems with moisture, mold, mildew and condensation
• offers excellent sound absorption and transmission properties because of its effective air seal
• a material that adheres well to steel studs, cement board, wood etc
• a material that remains flexible, allowing building materials to expand and contract with season and temperature changes, without developing cracks that would ultimately destroy the air seal

• acts as a physical and odor barrier for pests such as roaches, ants, mice and termites

How do costs compare with conventional insulations?

• while initially more expensive, the overall cost of a home, long-term energy costs, performance and comfort value make this a favourable medium
• additional upfront costs typically pay for themselves in energy savings within three years and will continue to save money every year thereafter
