Benefits of Spray Foam Insulation

Spray foam insulation offers some of the best insulation R-values available. This can help improve comfort and efficiency. Spray polyurethane (SPF), a versatile sealant and insulation, can be used to create an air barrier across multiple surfaces, such as ceilings, walls, and concrete slabs. Spray polyurethane is made by mixing two liquids that react quickly: polyol and isocyanate.

Closed-Cell and Open-Cell

Open-cell foam is usually 30% cheaper than closed-cell and has a lower R-value per inch. Open-cell foam must be applied thicker due to its lower R-value. It is, therefore, ideal for areas with more space such as attics and ceilings.

Closed-cell foam may be more expensive, but it pays off with a higher R-value per inch. It can also increase the structural integrity of walls and ceilings due to its ‘sticky qualities’ and rigidity after curing.

Air Leaks & Infiltration

Air infiltration can cause a building to lose up to 40% of its energy.

Air leaks and gaps waste expensive heating and cooling systems and increase energy bills. According to the U.S. Department of Energy, 56 percent of a home’s energy is spent on heating and cooling.

Spray foam insulation is an alternative to traditional insulation materials such as cellulose or fiberglass. It resists heat transfer, insulates, and seals any gaps. SPF creates an airtight barrier that prevents moisture, hot or cold air, and vapor from entering a building. It is also an effective sound barrier.

Energy Savings

Spray polyurethane expands when applied to fill in cracks and gaps and provide an airtight seal. According to the U.S. Department of Energy, a homeowner can save 15 percent in heating and cooling costs by using spray foam.

Spray foam insulation is a great way to seal air leaks in areas such as:

– Plumbing vents

– Attic hatches

– Wiring holes

– Behind knee walls

– Basement rim joists

– Windows and doors

– Open soffits

– Chaseways for recessed lights, furnace flues, or duct chase ways

Spray foam insulation offers excellent thermal performance and has the highest R-value per inch (a measure of thermal resistance), allowing it to provide greater energy savings than other insulations of similar thickness. The greater the R-value of a material, the better its insulating qualities.

Spray foam insulation has an R-value of 3.5-7 per inch of thickness. Some spray polyurethane foams can provide the same amount of energy savings with half the space.
