Closed Cell Polyisocyanurate Foam Core: Provides high R-value per inch in built-up, modified bitumen, metal roof and single ply roof systems, and approved for direct application to steel decks.
JM’s Polyisocyanurate foam, known as TRYMER® PIR, is a closed-cell, high-performance insulation for use in industrial and commercial applications. TRYMER PIR is manufactured into bunstocks to be fabricated into the appropriate shapes and sizes for pipes, vessels, equipment, and duct applications.
Johns Manville Polyiso foam continuous insulation boards provide a layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation.
Polyisocyanurate, often abbreviated as PIR, is a type of plastic commonly used in the construction industry due to its excellent insulation properties. It’s a thermoset polymer that is essentially an advancement of polyurethane (PUR) technology.
Polyisocyanurate (/ ˌpɒlɪˌaɪsoʊsaɪˈænjʊəreɪt /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
Using polyisocyanurate R-value per inch, we can calculate what is the R-value of any polyiso thickness. To help you out with this calculation, we have designed ‘Polyiso R-Value Thickness Calculator’.
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.
