Dyplast’s ISO-C1 polyisocyanurate rigid foam insulation line of products includes ISO-C1/2.0 (2 lb/ft3 density), the only polyiso insulation to be independently tested and audited by both Underwriters Laboratories and Factory Mutual. Our ISO-C1 polyiso insulation has superior physical characteristics, excellent water and moisture resistance, high R-factor of 5.7, and zero ozone depletion potential (zero-ODP) – – making it a cost-effective and environmentally friendly choice. Suitable for service temperatures between -297°F and +300°F, ISO-C1 polyisocyanurate insulation is well suited to a wide range of applications from chilled water pipe insulation to refrigeration insulation to cryogenic insulation.
ISO-HT is Dyplast Products’ 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation for higher temperature applications up to 375°F (190°C), with intermittent exposure up to 400°F (204°C). ISO-HT is suitable for constant temperature or heat cycling environments. ISO-HT is certified by independent laboratory to meet demanding Class 1 flame spread and smoke development requirements per ASTM E84.
