Closed-Cell Spray Foam Insulation vs. Rigid Foam Board
When choosing between closed-cell spray foam insulation and rigid foam board for exterior commercial wall assemblies, the importance of considerations such as price, design integration, and performance cannot be overstated. Spray foam insulation gets high marks in each of these categories making it your best choice for every commercial build. Let’s discuss the differences so you can make the right decision for your project:
CLOSED-CELL SPRAY FOAM
Increased design flexibility due to expansion upon application, allowing it to fit into tight spaces around window, door, and transition flashing systems
Lower overall cost due to reduced labor and material needs
Fully adheres to and seals construction gaps and penetration holes
30% higher r-value than rigid foam board
Provides energy code required air barrier as well as an effective water barrier and moisture vapor retarder
Saves nearly 40% of the cost of rigid foam board
50% faster application than rigid foam board
RIGID FOAM BOARD
Increased opportunities for penetrations due to mechanical fastening
Provides insulation and air sealing, as long as seams are sealed perfectly
Increased cost to install due to time-consuming installations: cutting panels to exacting sizes, ensuring seal and hold, etc.
Spray foam insulation often needs to supplement install to fully seal space between panels and/or hold panels in place
