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.
This review covers the current methods and challenges for the mech. recycling of the five main packaging plastics: poly(ethylene terephthalate), polyethylene, polypropylene, polystyrene, and poly(vinyl chloride) through the lens of a circular economy.
Polyiso is a rigid foam insulation used in over 70% of commercial roof construction, in commercial sidewall construction and in residential construction. The Benefits of using Polyiso include: • Low environmental impact • Virtually no global warming potential • Zero ozone depletion potential • Cost effective, optimized energy performance
31 maj 2023 · Easy to install, polyisocyanurate (polyiso) exterior wall insulation provides cost-effective, high-performing closed-cell, rigid foam continuous insulation in various types, sizes, and thicknesses to accommodate the specific needs of your project.
Polyiso possesses a high level of inherent fire resistance when compared to other foam plastic insulations due to its unique structure of strong isocyanurate chemical bonds. In 3 key fire tests - ASTM E84, NFPA 285 and NFPA 286/UL 1715 - polyiso performs exceptionally well.
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.
Polyiso insulation, a thermoset material, stays intact during the fire exposure and successfully performs by forming a protective char layer and remaining in place during the tunnel test, meeting the necessary ratings prescribed by building codes.
