Spray foam insulation or (SPF) Spray polyurethane foam is the most efficient, energy, and cost-saving option for your home or business. Whether the building is new or existing construction, from metal buildings to barns, spray foam products play a crucial role in ensuring buildings operate efficiently as a system, minimizing leaks and keeping conditioned air inside when applied to walls, roofs, ceilings, floors, basements, and foundations. Spray Foam is a 2-in-1 package that’s not just an insulator but also a superior air barrier.
UNDERSTANDING R-VALUES
R-VALUE is a measure of the capacity of a material to resist heat transfer.R-VALUE is a measure of the capacity of a material to resist heat transfer. An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value. The higher the R-value, the greater the insulating effectiveness. Though these values can change based on the type of construction and heating system used.

Air Leaks
New and existing construction, attics, under sub-floors, metal buildings, barns, and storage containers. It fills cracks, crevices, and voids and adheres to irregular surfaces or substrates to form an air sealing insulation. SPF provides sound reduction by blocking and absorbing air leakage which saves on energy costs and lowers utility bills. Insulation properly deployed can be part of a system designed to protect against moisture, which provides the benefit of reducing the chance of harmful mold, mildew and rotting of wood.
Spray Foam Insulation Information:
Spray foam insulation is an alternative to traditional building insulation, such as fiberglass. It is a two-component mixture composed of isocyanate and polyol resin that come together at the tip of a gun and forms an expanding foam. The foam can be sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled into the cavity of a finished wall. Both types of SPF are thermoset cellular plastics comprising millions of small cells. There are two different types of spray foam insulation:
Light-Density Open Cell (half pound foam):
Due to its ability to expand during the application process, ocSPF fills cracks, crevices, and voids and adheres to irregular surfaces or substrates to form an air sealing insulation.
It provides sound reduction by blocking and absorbing air leakage.
Reduces noise transmission.
Semi-rigid material with a sponge-like appearance that expands during installation and creates small, open cells that are filled with carbon dioxide. It can be crushed in your hand.
It is less expensive than traditional types of insulation such as fiberglass.
ocSPF has a typical R-value of 3.5 to 3.7 per inch.
It is usually only recommended for indoor applications.
We normally do not recommend using open cell foam in the Pacific Northwest.
Closed Cell (aka two-pound foam):
ccSPF creates an airtight barrier. When the required minimum thickness of 1.5-2 inches is installed, ccSPF is both a vapor barrier and an air barrier.
It is perfect for attics, exterior walls, and metal buildings.
Reduces noise transmission.
A moisture barrier is created.
It is rigid to the touch
Adds strength and rigidity for improved structural integrity.
There is a typical R-value of 6 per inch.
