The 100 series Technical Bulletins address key performance characteristics for the use of polyiso insulation in commercial and residential roofing applications. The covered topics include fire performance, tapered insulation systems, and best practices for storage, handing and installation.
1 sty 2017 · Abstract. The isocyanate-based polymers, including polyurethanes, polyureas, polyisocyanurates, and their copolymers, are found in the broadest range of applications. This comes from the high reactivity of the isocyanate group with any of the number of active hydrogen-containing molecules, of which the polyalcohols are available in profusion.
7 kwi 2020 · Polyisocyanurate is a closed-cell insulation material that contains a blowing agent within its cells to reduce the rate of heat transfer. Similar to other blown insulating foams, the blowing agent diffuses over time, resulting in a change in R-value. This change in R-value is known as thermal drift.
Fire Test Standards for Polyiso Insulation and Roof Assemblies Polyisocyanurate (polyiso) has a proven track record of performance in low-slope roofing applications. The performance benefits of polyiso, such as its high R-value and excellent fire test performance, make polyiso an excellent
