Using spray foam insulation vs. rigid XPS foam board in CMU exterior block walls
Architectural firms choosing to specify CMU exterior block walls rather than steel framing walls are also able to achieve significant cost savings. Like steel framing exterior walls, a closed cell medium density spray foam insulation product like Icynene ProSeal Eco, in a CMU exterior block wall provides three solutions – insulation, air barrier and vapor retarder. Furthermore, it will also smoothly and completely cover 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.
The detailed graphic below shows the cost comparison between spray foam insulation and rigid XPS foam board for a typical CMU exterior block wall assembly. The installation of a high performance, multi-faceted spray foam product like Icynene ProSeal Eco not only allows for significant building material savings but also labor cost savings and allows for construction to remain on - or be ahead of – schedule.
