What is Spray Foam?

Polyurethane spray foam is an advanced insulating system that prevents air, moisture and vapour from entering your walls, floors and roof. It spreads easily and evenly to seal cracks, leaks and air pockets, thereby eliminating drafts, cold spots and dampness as well as mould and mildew. Applied as a liquid, it expands to more than 100 times its size. It can be used to effectively seal any space from your basement to your attic, in any architectural design.


Types of Spray Foam

There are 3 different types of spray foam; each has its own benefits.

  • High density spray foam is typically used for roofing and exterior applications
  • Medium density spray foam is preferred for continuous insulation of interior cavities and unvented attics
  • Low density spray foam can also be used in interior cavities, unvented and vented attics and crawl spaces, but is permeable to moisture

The trained and experienced technicians at Platinum Spray Foam can help you select the right type for specific areas in your building. Proper installation is also key to optimizing its performance. When applied correctly, you can save up to 50% on your energy bills.

Open Cell vs. Closed Cell Spray Foam

As the name suggests, in closed cell spray foam, the cells are tightly packed together when compared to the open cell foam which is the least expensive type. Density naturally determines the strength and level of protection you enjoy. Here are some key points of differentiation to consider.

Open Cell Spray Foam

Closed Cell Spray Foam

  • Density range is 0.5lb per cubic ft. to 1.2lb per cubic ft.
  • Density range is 1.7lb per cubic ft. to 2.2lb per cubic ft.
  • R-values ranging from R-3.6/inch to R-4.5/inch
  • R-values vary from R-5/inch to R-7/inch
  • Acts as a sound barrier to create a quieter indoor environment
  • High density, compression strength and low vapour permeability adds structural integrity
  • Generally applied to the above ground walls, underside of the roof in an unvented attic, and wherever sound reduction may be required
  • Typically recommended for below grade foundation walls (basement walls), indoor swimming pools, wine cellars, freezers, etc.
