Commercial title

For commercial construction purposes, squirted out polyurethane moss is the process that has the best R-value at a given thickness.

R Value

The higher the R-value is, more resistant to high temperature it is and higher the energy savings are.


Polyurethane moss has the highest fire resistance of all insulation materials on the market with an R-value R-6 to R-7 per inch thickness.

Polyurethane moss has to be applied to dry and clean of solvent and fat surfaces at temperature of –10 to +40 degree C. Isolation 4 Saisons has available all necessary skill people to perform most professionally.

Most building owners are not aware that waterproofing is ruled in the Canada Building Statute-book when there is a hydrostatic pressure and take on their own to blow an ordinary waterproofing material that will slowly let humidity through.

In many instances this will be accepted by the inspectors but in time clay piping will get blocked and the icing un-icing phenomena weakening the building foundations will cause concrete to crack and then water infiltration. Waterproofing creates a barrier against water infiltration therefore against humidity from most Canadian soil content. High dampness will generate moisture and rot with all it may means only to save less than 10.00$ per month on the average home mortgage.

The waterproofing self-adhesive membrane “SBS” (rubber-coated) developed for installation in low temperature conditions (down to –4 degree C) is controlled for thickness while under production and offers excellent jointing characteristics resulting in a sturdiest assembly.

Originally engineered for the commercial construction, the membrane that we use at Isolation 4 Saisons is the best waterproofing material on the market to date. The membrane is as good for vertical as for horizontal application.
