News Release

MIAMI - (April 15, 2009) - National attention on energy efficiency has focused on the key role insulation can play. This bulletin is intended to offer information and some clarification regarding recent industry-leading test results from Dyplast Products testing.

Dyplast Products has announced that third-party testing confirmed that its ISO-C1 polyisocyanurate insulation has the best thermal resistance of any competitive insulation. ISO-C1, at 2 lb/ft³ density, achieved a 6-month aged K-factor of 0.176 which equates to an aged R-factor of 5.7. Combined with ISO-C1/2.0's initial R-factor of 6.7, this product has thermal resistances higher than virtually all commercial insulations available; and approximately double that of fiberglass or mineral wool.

In fact, this R-factor is approximatley double that of fiberglass or mineral wool [note that testing per ASTM is at 75F, even though the R-factor of ISO-C1 improves at lower temperatures];

2", 3" and 4" thick samples of ISO-C1/2.0 which were selected by RADCO personnel during an audit conducted at the Dyplast facility. The final 6 month aged K-factors are essentially independent of thickness, with aged values virtually identical. The good news does not end there. The results are actually better than Dyplast's previosuly listed values of 0.180 k-factor at 1" thickness. Averaging two samples at each thickness, the results were:

• 2.0" thick: K-factor of 0.1763 (core density = 2.09)
• 3.0" thick: K-factor of 0.1762 (core density = 2.01)
• 4.0" thick: K-factor of 0.1756 (core density = 2.02)

Recall also that ISO-C1/ 2.0 is the only two pound density polyisocyanurate bunstock foam that has both UL Listings and FM Approvals for flame spread and smoke development per ASTM E84. UL and FM are two of the most respected testing agencies in the world. No other manufacturer has passed Class 1 at either UL or FM. To maintain our certifications with the testing agencies, Dyplast Products is required to undergo on-site audits up to 4 times per year. Furthermore, to our knowledge, no other manufacturer of polyisocyanurate bundstock has achieved a Class 1 ASTM E84 certification by independent laboratories.
