About Spray Foam Insulation

Spray Foam Insulation saves You Money and Pays for Itself
 Spray Foam Insulation saves on energy costs and lowers utility bills. Spray Foam Insulation is used to seal the entire “building envelope” of your home 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 Spray Foam Insulation, saving money yet again.

High R-Value
 Sprayed polyurethane foam has an aged R-value of approximately 6.0 per 1 inch thickness (depending on the particular formulation and application, higher values have been achieved), enabling it to provide more thermal resistance with less material than any other type of commercial insulation material. Spray Foam Insulation systems are frequently used to insulate and protect a wide variety of residential, commercial, and industrial buildings.  Monthly energy and utility savings of 30% or greater can be achieved when compared to the alternative roofing and insulation systems. The cost of an Spray Foam Insulation roof or insulation system can often be recovered in less than 5 years, simply through energy savings alone.

Prevents Air, Moisture and Gas Infiltration
 Studies have shown that as much as 40% of a building’s total energy loss is due to air infiltration. Traditional fiberglass insulation is only stapled, or placed into the wall cavities and does not seal the stud and wall cavities from end to end, or top to bottom. Air infiltration can pass through these gaps, making it far less efficient than Spray Foam Insulation. Spray Foam Insulation not only adheres to, but forms to the walls and floors to create a tight seal and insulating barrier that stops this air leakage. Spray Foam Insulation also boasts the highest R-value per inch than any other commercial material, (upwards of R-7.0, compared with Fiberglass at R-3.5) making your home more comfortable and less expensive to heat in the winter, and cool in the summer.  Since Spray Foam Insulation acts as an air barrier, it also helps to reduce moisture infiltration, which is a source of dangerous mold and mildew growth in the home, and can cause severe health problems to its occupants. So save your family and save money at the same time with Spray Foam Insulation home insulation systems. Moisture infiltration can also cause structural damage to your home or building

Products used by Porter's Spray Foam

Open-Cell Spray Foam Insulation

 *Most common in home insulation

Open-cell spray foam insulation is spray applied in a liquid, expanding to 100 times its volume. Once applied, the product cures within seconds, filling every crack and gap. The tiny cells expand at such a rapid rate that they break apart and fill with air, creating a soft, almost spongy end product. The rapid expansion of open-cell foam creates a perfect air-tight seal using less material than closed-cell foam, thereby creating a lower cost per R-Value.

R-value of 3.7 per inch
Lowest cost among all types of foam
Excellent noise reduction and sound control

Common Applications

·         Stud walls
Attics
Air Sealing
Sound Control

Closed Cell Spray Foam Insulation

Closed-cell foam insulation is a more slowly expanding product, resulting in an expansion of approximately 40 times its original volume. The closed-cell nature of this type of foam creates a tightly packed cell structure that is more rigid and dense than open-cell foam, giving closed-cell foam a higher R-value per inch. With closed-cell being four times the density of open-cell foam, the cost per R-value is higher for closed-cell foam than that of open-cell foam insulation.

R-Value of 6.8 per inch

Enhances structural integrity
Qualifies a vapor retarder at 2”
