Pentoir Spray Foam Systems Benefits

There are quite a few benefits associated with Spray Foam Insulation. They range from utility bill savings, air infiltration protection, structure strength, tax benefits, etc. These benefits affect your wallet, your health and the environment. The most common reason consumers invest in SPF is for the monetary savings.



  • Less energy used = cheaper utility bills
  • High R-value per inch (open cell 4.21/closed cell 6.7)
  • Air infiltration eliminated
  • Moisture and condensation controlled (closed cell only)


  • Improves indoor air quality
  • Seals out dust, pollen, insects and rodents
  • Infiltration of outside air pollutants reduced
  • Mildew and mold growth within the building reduced


  • Increases structural strength
  • Reduces sound transfer
  • Boosts resale value
  • HVAC size reduction


  • CO2 emissions reduced
  • No formaldehyde or ozone depleting substances
  • LEED credits for sustainable, green construction can be earned
  • Structural damage caused by high winds resisted

Saves You Money and Pays for Itself

SPF home insulation saves on energy costs and lowers utility bills. SPF 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 SPF, saving money yet again. Homes insulated with Spray Foam have a higher resale value. Reduced heating and cooling load on HVAC will lead to fewer repairs and breakdowns. Downsize HVAC equipment by 30%.

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). SPF will provide more thermal resistance with less material than any other type of commercial insulation material. SPF 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 SPF 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 total energy loss is due to air infiltration. Traditional fiberglass insulation is only stapled, or placed into the wall cavities and do 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 SPF. SPF not only adheres to, but forms to the walls and floors to create a tight seal and insulating barrier that stops this air leakage SPF won’t sag, shift or degenerate and will perform throughout the life of your home. SPF 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 SPF 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. SPF is bio-based and non-toxic. You can save your family and save money at the same time with SPF home insulation systems. Moisture infiltration can also cause structural damage to your home or building.

Helps Reduce Moisture and Mold

Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed. There is no practical way to eliminate all molds and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture. SPF insulation is the key.



Breathe Clean Air

Pentoir’s Spray Foam insulation eliminates air infiltration and seals a building so tight that an air to air exchanger must be installed. This results in premium indoor air quality (IAQ) because dust, fiber, pollen and other pollutants have no way in.

Our foam application emits no VOC's or CFS's during application or throughout the life of the product.

Inhalation of toxic molds has proven a problem for homeowners and insurance companies. Pentoir’s Spray Foam insulation eliminates breeding ground for mold because it eliminates the entry of mold spores and prevents moisture accumulation.

Also since spray foam expands into the smallest cracks and holes it has proven to reduce the entry of unwanted pest and insects. Spray foam is a polyurethane product and does not act as a nesting ground or source of food for pests.

Create Structural Strength

The application of spray foam actually strengthens a building structure. The expanding foam fills the gap between each wall, floor or roof cavity. The studs, joists and sheeting are bonded together creating optimum structural strength. After curing, spray foam is durable and will not shrink, settle or disintegrate over time.

Boost your home’s resale value. A well-sealed home is a better performing home. And that can affect your home’s resale. Home inspections and lower energy bills will confirm Spray Foams superior thermal efficiency.

So investing in Spray foam insulation not only enhances the comfort, energy efficiency and structural integrity of your home, it also can pay back again when it comes time to sell your home.

Spray Foam Adhesives Proven To Strengthen Your Building's Roof

"In a test conducted by Clemson University's Civil Engineering Department in 1998, it was demonstrated that roofs with SPF adhesive can withstand 2 to 3.5 times more uplift resistance than roofs held together with nails alone. In one test sequence using 5/8 nailed OSB, the roof system had an uplift resistance of 87 pounds per square foot. The addition of SPF adhesive increased the uplift resistance to 314 pounds per square foot." (Spray Foam Magazine September 2011)
