7 paź 2020 · Polyisocyanurate thermal insulation, commonly referred to as polyiso, has proven to be popular due to a combination of its cost effectiveness (i.e. cost per insulation unit), efficiency (i.e. insulation value per unit thickness), and fire resistance, as compared to some competitive materials.
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
POLYISO is a versatile, high-performance insulation solution that is suitable for a multitude of applications. POLYISO is most commonly used as a continuous insulation for roofs and walls, and as a protective roof cover board.
1 mar 2020 · Specifications. NRCA recommends designers specify polyisocyanurate insulation using the ASTM C1289 designation followed by the specific type classification and, if applicable, class and grade classifications necessary to identify the intended products’ compressive strength and facers.
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.
Polyiso insulation products are easy to specify and meet the requirements of both ASTM C1289, Standard Specification for Faced Rigid Cellular Polyisocyanurate Thermal Insulation Board and CAN/ ULC-S704 Standard for Thermal Insulation, Polyurethane and Polyisocyanurate, Boards, Faced.
2 lip 2001 · Polyisocyanurate foam insulation (polyiso) is clearly the best product to use with today’s roofing systems to provide efficient and cost-effective insulating properties. Polyiso roof insulation represents more than 55 percent of all insulation used in low-sloped roof construction.
