Why Spray Foam?

The All-in-One Wall System Concept puts insulation, air and vapour barrier into one product. POLARFOAM PF-7300-0 SOYA is fully self-adhered to the substrate, which increases the integrity of your building by 300%. It also helps keep rodents and insects out of the spray foamed area.


Independent laboratory tests confirm the on-site long-term thermal performance of POLARFOAM PF-7300-0 SOYA spray foam insulation in the building envelope system increases thermal performance of the building envelope.

Air Barrier:

Research shows that 40% of building heat loss can be attributed to air leakage conducted through the building envelope. Tests for air leakage show that POLARFOAM PF-7300-0 SOYA exceeds 500 times the requirements of the National Building Code as an air barrier material.

Results confirm that POLARFOAM PF-7300-0 SOYA is one of the highest performance air barrier materials on the market, and this feature is the key element in an air barrier system that meets the objectives of the National Building Code.

By creating a sealed air barrier and eliminating air filtration, POLARFOAM PF-7300-0 SOYA does not allow wall condensation that can often result in mold, mildew and wall degradation.

Vapour Barrier:

Water vapour permeance is the speed to which water goes through a homogeneous material. The National Building Code stipulates that a vapour barrier must have a water vapour permeance less than 1.05 PERM (60 ng/Pa*s*m2)

  • ##75 mm of POLARFOAM PF-7300-0 SOYA spray applied on an exterior gypsum board = 44 ng / Pa*s*m2 (0.77 PERM)
  • ##75 mm of POLARFOAM PF-7300-0 SOYA spray applied on concrete blocks = 22 ng / Pa*s*m2 (0.38 PERM)

Air infiltration is a vicious circle. In cold weather, heat escapes and in warm weather, cool air escapes.  Air infiltration takes away your energy efficiency!

POLARFOAM PF-7300-0 SOYA is an environmentally friendly, high performance, closed cell rigid polyurethane foam used for insulation, and is a spray applied exclusively by certified applicators. It is being used by architects to design buildings that are attractive and comfortable for the occupants, inexpensive to operate and maintain, and remain so for the life of the building.

POLARFOAM PF-7300-0 SOYA is a spray-applied cellular plastic that forms a continuous, monolithic barrier on walls, around corners, and on all contoured surfaces and protrusions. Due to the fast installation, it decreases your construction costs while increasing the energy efficiency of your building envelope.

POLARFOAM PF-7300-0 SOYA has been designed for use in the following building types:

  • Commercial
  • Residential
  • Industrial
  • Agricultural
  • Institutional
