News Release

MIAMI - (November 30, 2005) - Dyplast Products, LLC today announced that its ISO-C1 polyiso foam insulation achieved aged K-factors of 0.18.

The 0.18 aged K-factor of Dyplast's ISO-C1 (2.0 and 2.5 lb/ft³ densities) has raised the bar for thermal conductivity expectations for polyisocyanurate rigid foam insulation. Prior to this milestone achievement of Dyplast Products, the insulation industry has assumed that the long-term insulating value of polyisocyanurate foam with hydrocarbon blowing agents was inferior to foams made with HCFC blowing agents (now banned per the Montreal Protocol).

Tests by an independent laboratory in accordance with ASTM C518 standards showed an aged K-factor of 0.18 BTU·in/hr·ft²·°F for both ISO-C1/2.0 and ISO-C1/2.5, equating to an R-factor of 5.6 hr·ft²·°F/BTU. Aged K-factors are achieved by testing the thermal conductivity after aging the insulation in a controlled environment over six months. Thermal conductivities measured under this scenario have been demonstrated as comparable to the "lifetime" performance of the insulation in actual use at a nominal temperature of 75°F. Dyplast's ISO-C1 products exhibit even better K-factors at the lower temperatures inherent in most polyiso applications such as chill water, LNG, and other cryogenic applications.

Dyplast Products was able to achieve this high K-factor through improved proprietary formulations and rigorous process control. "While some polyiso manufacturers and suppliers have been lobbying for lower C-591 standards for polyiso thermal conductivity, Dyplast has demonstrated that we can meet existing standards", says Ted Berglund, Dyplast CEO. "Dyplast's K-factor milestone puts ISO-C1 ahead of the polyiso competition, and deflates arguments put forth by extruded and expanded polystyrene suppliers that their foams are comparable."
