WHAT IS SPF INSULATION?
Professional Roofers can apply Spray Polyurethane Foam (SPF) insulation directly to the roof deck and other attic areas creating an unvented attic (UVA). The use of SPF insulation can also help tie together the attic and wall insulation, creating a continuous insulation system.
WHAT ARE THE ADVANTAGES?
SPF is the ideal choice for UVAs because it acts as an insulation and air sealant. SPF expands on application, filling gaps and sealing air leaks in the attic wall and roof. This helps prevent air infiltration and can reduce energy consumption.
IS IT WORTH IT?
Air leakage usually exceeds 20 percent of conditioned air flow, which results in a significant energy loss. It also reduces the loss of conditioned air through the attic. A UVA can keep a home warmer in winter and cooler in summer, reducing the HVAC load. UVAs in most cold climates decrease the heating load by about 10 percent, saving you money on energy costs.
CAN I INSTALL SPF IN MY EXISTING HOME?
Both new and existing construction can be designed for UVAs, meaning all homeowners have the opportunity to benefit from energy savings. In a new building, the UVA can be installed during the construction process with SPF applied directly on the underside of the attic walls and roof, leading to maximum coverage and air sealing. In an existing building, the spray application for SPF allows the product to be applied around any existing obstacles and into the hard-to-reach spaces of an attic.
HIRE AN EXPERIENCED CONTRACTOR!
To ensure that SPF is properly installed, it is important to choose a properly trained installer. A trained SPF contractor can answer your questions on product selection and application process. Also, ask them to provide the proper documentation stating they are licensed to apply SPF solutions.
