Calculating Yield in Spray Polyurethane Foam Applications

Calculating Spray Foam Yield

A common question among spray foam contractors is “how much yield can I get from my spray foam?” Obtaining good yield from your spray foam can lead to a better bottom line. In many cases, a spray foam contractor will base their purchasing decision on the yield they expect to obtain from a nominal low density, medium density or high ...

The Many Uses and Benefits of Open-Cell Spray Foam Insulation

Open Cell Spray Foam Benefits

Like its name suggests, open-cell foam is made up of tiny bubbles, or cells, that are interconnected. The cells hold air, which provides insulation value – typically between R-3.5and R-4 per inch. Like closed-cell foam, open-cell foam expands to fill gaps and cracks as soon as it’s applied. One of the first noticeable differences with open-cell spray foam is that ...

Ignition Barriers and Thermal Barriers in Attics: International Residential Code (IRC) Requirements

The 2009 International Residential Code establishes prescriptive and alternative performance requirements for spray polyurethane foam (SPF) plastic insulation when installed in residential attic applications to ensure adequate performance of foam in a fire. Meeting Code Requirements: There are two ways to meet the requirements for an ignition barrier or thermal barriers. The first way is the prescriptive requirements listed in the ...

Unvented Attics for Existing Buildings

As residential construction has slowed over the past few years, many insulation contractors have turned to weatherization projects that add insulation and air sealing to existing homes. For SPF contractors, one of the easiest and most accessible areas to insulate and air seal is the band joist and to create unvented attics and crawlspaces. Unvented attics can be easily created ...

Closed-cell Spray Foam: the Only FEMA Class 5 Rated Flood-Resistant Insulation

Sprayed polyurethane foam and closed-cell plastic foams are the only materials that FEMA classifies as acceptable flood damage-resistant insulation materials for floors, walls and ceilings in its building design criteria for special flood hazard areas (SFHAs). This requirement applies to new construction, repair of substantially damaged buildings, and substantial improvement of existing buildings in SFHAs. To protect buildings constructed in ...

Monolithic Domes: Quite Possibly the World’s Safest Severe Weather Buildings

Monolithic Dome Home with Spray Foam

A Monolithic Dome starts as a concrete ring foundation, reinforced with steel rebar. For smaller domes, an integrated floor and ring foundation may be used. Vertical steel bars embedded in the ring beam footing are later attached to the steel, reinforcing the dome itself. The Airform, fabricated to a proper shape and size, is attached to the concrete base. Using ...
