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.
28 lip 2021 · Rigid foam insulation boards are different. Choose carefully between Polyisocyanurate, EPS & XPS or Mineral Wool & Hemp as the wrong choice can reduce insulation performance & cause mold & rot in building envelope's. Ecohome Updated: July 28, 2021. Mike Reynolds.
POLYISOCYANURATE FOAM INSULATION DESCRIPTION Trymer® 2000XP insulation is a closed-cell insulation that features improved dimensional stability over a wider range of temperatures than standard polyurethane insulation. Trymer 2000XP insulation is polyurethane modified polyisocyanurate (PIR) cellular plastic. The rigid insulation is supplied in the
Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
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 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.
