Top reasons to pick closed-cell spray foam over rigid foam board insulation

Today’s modern commercial buildings require high performance building materials to optimize functionality and energy efficiency.  When compared to traditional alternatives available in the market, such as rigid foam board, spray foam insulation is a modern approach to continuous insulation that allows architects to push the envelope in design and creativity.  The following overview identifies why closed-cell spray foam is the superior choice for continuous insulation applications in commercial building design.

Plus, the infographic below provides a visual snapshot of the advantages of closed cell spray foam over rigid XPS foam board in continuous insulation applications.

Spray Foam has a lower installed cost
One of the biggest advantages of choosing closed-cell spray foam over rigid foam board insulation in a continuous insulation application is its lower installed cost. A three in one solution – insulation, air barrier and vapor retarder – closed-cell spray foam insulation requires less materials, and less labor, to completely seal the exterior wall assembly. This elimination of additional materials, such as a polyethylene and rubberized asphalt sheet barrier, drives overall installed costs down.

Spray Foam's simple installation is a big plus
In addition to greater functionality than rigid foam board insulation, spray foam is also easier  to install. Closed-cell spray foam insulation smoothly and completely covers all areas that could otherwise provide energy draining thermal bridges. The end result is a total high-performance wall assembly solution that can enhance and work with virtually any architectural design approach.  Rigid foam board, on the other hand, requires the addition of air barrier material, mechanical fastening (creating numerous wall penetrations) and taping at every joint. Furthermore, the flat panels of rigid foam makes it difficult to install on curved surfaces of a commercial building.
