Unvented Attics

spray foam equipmentAttention spray foam contractors: did you know that unvented attics (UVAs) insulated with spray polyurethane foam (SPF) can actually help improve the overall energy efficiency performance of a home or building?

So, how does it work?

Unvented attics move the insulation and air barrier from the attic floor to the underside of the roof deck. Transferring this system to the roof brings the attic and any equipment and ducts inside the building’s conditioned space. As a result, this helps to improve the energy performance of the building by reducing temperature variabilities in the attic and energy loss that can often result from previously leaky ductwork.

As an insulation professional, you can apply SPF insulation directly to the roof deck and other attic areas creating a UVA. Another benefit: the use of SPF insulation can also help tie together the attic and wall insulation, forming a continuous insulation system in the building envelope.

Benefits of SPF for Unvented Attics

Industry experts have pointed recently out that SPF is ideal for UVAs because it acts as both an insulation and air sealant. Spray foam expands on application, filling gaps and sealing air leaks in the attic walls and roof.

Ultimately, this can help prevent air infiltration and reduce air-conditioning loads offering further reductions in overall energy consumption.

Here are some other advantages:

  • Compensates for leaky ductwork in an attic space. Typically, duct air leakage exceeds about 20 percent of conditioned air flow, resulting in a major energy loss when ducts are in unconditioned space. UVAs can capture air loss from leaky ductwork and return the air into the conditioned space.
  • Reduces the loss of conditioned air through the attic. Similar to wearing a hat on a cold day, UVAs help reduce energy loss through a home’s attic. An UVA can keep a home warmer in winter and cooler in summer, reducing the building’s overall HVAC load. IN fact, according to a recent report, UVAs in many cold climates decrease the heating load by about 10 percent.

In an effort to meet customers where they are today, we believe it’s important for companies to realize that superior customer service – especially in the SPF insulation and equipment industry – isn’t just about the way you greet and serve your customers. In our latest research project, we’ve developed a new eBook: “Are You Getting the Best Customer Service from Your Spray Foam Equipment Provider?
