Spray Foam Insulation
Spray Foam Pays for Itself! There isn’t a better insulating material that can seal your building or home from air and moisture intrusion, save you money on costly utility bills, add strengthen your building, and protect your air quality from dangerous mold, airborne pollutants, and allergens than Spray Foam insulation.
SPF insulation saves on energy costs and lowers utility bills. SPF is used to seal the entire “building envelope” to prevent air and moisture infiltration. The US Department of Energy (DOE) studies show that 40% of your home’s energy is lost due to air infiltration. This air infiltrates the home in the form of drafts through walls sockets, windows and doorways. Often times no expensive building wrap or additional vapor protection is required during construction when using SPF, saving money yet again.
Since SPF is an effective air barrier it also aids in reducing the moisture infiltration which is a source for mold growth and mildew buildup in your property.
Closed Cell SPF also increases the structural soundness to the applied building. By interlocking all flexible parts of your building (studs, walls, sheathing, purlins, tin, plywood, etc) SPF increases the “Racking and Shear” loads of the structure by upwards of 200%, creating a stronger and safer place to live or work.
What is SPF?
Spray Polyurethane Foam is an alternative to traditional roofing and insulation such as single-ply membrane or fiberglass insulation. SPF is a plural component mixture composed of Isocyanate and Resin and comes together at the tip of a spray gun under heat and pressure, and forms an expanding foam that is sprayed onto roofs, concrete slabs, into wall cavities, or on to any application or substrate.
Polyurethane is the most common type of spray foam insulation and was developed and used by the military in the 1940s. It wasn't until the 1960s that SPF began to creep its way into the commercial insulation and roofing market.
Two Different Types
Choosing Between the Two:
Both types of foam are commonly used in most building applications and the choice for which to use can depend on many factors. Some foams types are inappropriate in specific applications. For example, you typically would not use open-cell foam below grade or in flotation applications where it could absorb water; this would negate its thermal performance because water is a poor insulator compared to air. Closed-cell foam would be a good choice where small framing sizes need the greatest R-value possible per inch and the structural aspect of the foam is desired. Closed-cell foam is also used for roofing applications and exterior waterproofing.
