Frequently Asked Questions About Spray Polyurethane Foam (SPF) Insulation

What is Spray Foam Insulation?

Spray polyurethane foam (SPF) is a spray-applied synthetic material which produces a continual insulation and air sealing barrier within wall structures, roofing systems, around corners as well as various other surface areas. SPF insulation is recognized as a material which withstands heat transfer quite effectively and provides an extremely efficient solution in minimizing excess air infiltration.

What is the main benefit of Spray Foam Insulation?

The primary benefit of spray foam insulation is energy efficiency.

As much as 40% of a building’s energy is actually wasted as a result of air infiltration. Cracks, gaps and holes, as well as air leakages, can easily help make utility costs needlessly high. Spray foam acts as both insulation and as an air barrier, sealing openings which allow air to escape and therefore increases reoccurring energy
expenses.

As much as fifty percent of the energy utilized within a house is applied to home heating and cooling, based upon a report by the EPA. Sustaining an ideal home heating, ventilating, and air conditioning (HVAC) equipment could help to make your residence much more energy efficient. With spray foam, HVAC specifications may possibly be reduced as much as 35%.

Air leaks – which can lose energy and drive up utility costs – can be filled with spray foam. A few typical locations for air leaks which can be sealed off with spray foam include the area behind knee wall structures, attic hatches, electrical wiring openings, plumbing vents, exposed soffits, recessed light fixtures, furnace flue or ductwork chaseways, basement rim joists, doors and windows.

“Cool roofs” are designed to sustain a lower temperature compared to conventional roofing systems. They are light-toned in color and reflect sunlight. Spray foam installed on the roof of a structure can offer cool roof efficiency when covered with a protective, reflective coating. Spray foam roofs do not require metal fastening, eliminating the possibility for thermal shorts or bridges which enable heat to enter.

What other benefits does Spray Foam Insulation offer?

Two additional benefits of using Spray Polyurethane Foam (SPF) insulation: improving building strength and durability, and improving the indoor environment of the structure.

Installing an SPF roof can possibly increase a building’s strength. SPF roofs have effective lifespans that can exceed 30 years. SPF can help develop a tough bond to secure the roof and can prevent water infiltration by means of vulnerable points. It can also be installed in a sloped technique in order to permit water to quickly drain away from the roof.

The bond which SPF forms can improve a building’s level of resistance to wind uplift. During periods of strong wind, a structure using a spray foam roof typically experiences less damage compared to a building without SPF. One well-known spray foam technical expert observed that “when added to the inside of a structure, spray foam ‘glues’ the whole building together, enhancing overall wind and pressurization resistance.”

SPF insulation adds strength and durability. The Federal Emergency Management Agency (FEMA) has categorized SPF insulation as highly resistant to floodwater damage, saying, “These materials can survive wetting and drying and may be successfully cleaned after a flood to render them free of most harmful pollutants.”

Spray foam protects against moisture and condensation throughout the structure, helping prevent mold and mildew. Applying closed-cell spray foam within the cavities of the wall structures increases resilience of the wall system due to its ability to conform and adhere to the surface area upon which it is applied. A wall with spray foam insulation is far better able to maintain its shape under duress than a wall assembly with no spray foam.
