The push toward HFO-based sprayfoam blowing agent technology is the latest step in an ongoing evolution to phase out the use of chemicals known to harm the ozone and climate. In addition to reducing the negative Earth impacts of sprayfoam insulation and roofing materials, there are also product performance and installation considerations. This article will explain the blowing agent shift and why it matters to those considering the specification of sprayfoam for both insulation and roofing applications in commercial building projects.
If building managers cannot adequately control water and moisture permeation within their wall assembly due to natural events and poor design, it can cause extensive damage, impact aesthetics, and contribute to poor indoor air quality (IAQ) and mold growth, which is proven to have harmful effects on the health and well-being of occupants. Polyiso continuous wall insulation not only resists water but also offers superior thermal resistance to help ensure long-term energy efficiency within the building envelope.
The goal of this article is to help specifiers and designers know what project needs drive the facing profile, gauge, color, and insulation thickness selections for IMPs, as well as the best applications within the range of options available.
There are several avenues which can be used to attack the problem of thermal bridges, including changing design elements, improving team communication, and promoting understanding of thermal bridging.
