Polyiso Insulation

The foam insulation board with the highest R-Value in our arsenal is Polyiso. Polyiso, or polyisocyanurate, is a type of rigid foam insulation that is popular with commercial roofing applications (low slope) and wall assemblies. This is the most widely available rigid foam insulation board in North America because of its cost-effectiveness and its effectiveness in reducing energy consumption.

Polyiso is made up of four major components namely MDI, polyol, a flame retardant, and a blowing agent. When the 4 components are mixed and small amounts of surfactants and catalysts added, a heat-generating chemical reaction occurs and it causes the blowing agent to boil, expanding the foam and creating gas-filled cells with high thermal resistance or R-Value.

The polyiso we have in our stock use hydrocarbon blowing agent pentane for zero ozone-depletion. The R-Value is between 7.0 and 8.0, depending on the product.

Polyiso (polyisocyanurate) is a rigid foam insulation that consists of organic and inorganic materials. Polyiso insulation is bonded to facers on both sides and can be used in walls, ceiling, roof, and other specialty applications within residential and commercial buildings. Because of its high performance, polyiso rigid foam insulation board is the product of choice among established architects, builders, contractors, and consumers in Toronto. The foil-faced polyiso foam insulation provides excellent heat, moisture, and air control, eliminating major thermal bridges that might cause heat loss.

Polyiso insulation is Toronto’s most widely used, most cost-effective, and readily available insulation product. Why choose polyiso insulation Toronto?

  • Compared to other insulation products used in residential and commercial establishments, polyiso has a higher R-value per inch.
  • The insulation records exceptional performance in fire tests.
  • Polyiso is stable over a wide temperature range.
  • It’s not affected by oil-based waterproofing compounds, fertilizers, and insecticides as long as it’s well protected.
  • Polyiso foam board insulation is resistant to fire and moisture. The insulation will maintain its physical characteristics even when exposed to extreme temperatures.
  • Its sizing and lightweight makes polyiso easy to handle and install

Polyiso consists of four main products: a polyol, MDI, a blowing agent, and a flame retardant. The four components are mixed, and small amounts of catalysts and surfactants are added. This leads to a heat-generating chemical reaction that causes the blowing agent to boil and expand the foam resulting in gas-filled cells with a high R-value.

Is Polyiso Insulation Safe?

Polyiso insulation is not only efficient but also sustainable. It has a low global warming potential (GWP). Of all the insulation materials, polyiso has the highest R-value per inch and the lowest GWP compared to other rigid insulation products. PIMA (Polyisocyanurate Insulation Manufacturers Association) has completed third-party verification of ISO-compliant EPDs for polyiso insulation. The energy savings potential of the insulation over its lifespan is many times the energy required in producing, transporting, installing, maintaining, removing, and disposing of the insulation.

Polyiso is one of the most environmentally friendly insulations. It has a high insulation value and doesn’t have a high global warming potential.

How long does it last?

Polyiso foam board insulation could have a lifespan of 100 years or even longer.

Does it absorb water?

Polyiso rigid foam insulation board is manufactured with a closed-cell structure. This makes polyiso insulation waterproof. The insulation is suitable for areas that are prone to moisture.
