News Release

MIAMI - (January 29, 2009) - Dyplast Products, LLC announces industry-leading results regarding it's ASTM E84 flame spread/smoke development test conducted by UL and FM; and adds clarity to often mis-understood claims regarding flame/smoke properties of alternaitve insulations.

• ISO-C1/ 2.0 is the only two pound density polyisocyanurate bunstock foam that has both UL Listings and FM Approvals for Class 1 flame spread and smoke development¹. UL and FM are two of the most respected testing agencies in the world, and a certification by either is challenging. To maintain our certifications with the testing agencies, Dyplast Products is required to undergo on-site audits up to 4 times per year;

• ISO-C1/2.0® has obtained the following independently verified test results²:

• an E-84 rating at 1 inch thickness of 20/55 (FM)
• at 4 inches thick² a 25/130 measured by FM¹, and
• at 4 inch thickness a 25/195 as measured by UL;

• No other US polyisocyanurate foam manufacturer has achieved a Class 1 at either UL or FM, and as far as we are aware no other US polyisocyanurate foam manufacturer has obtained an official Class I certification at any other ASTM E 84 testing facility;

• Because the E-84 test results can vary from test to test, all certified listings or approvals specify that the average should be based on three tests. For example when Dyplast burned its ISO-C1/2.0 at 1 inch with FM the individual test results varied from 15 to 20 for flame spread and from 45 to 75 for smoke;

• Two other significant factors influencing the smoke ratings are the foam thickness and the foam density since smoke levels are proportional to the mass of foam being tested. Thus it is incorrect to suggest that one Class 1 foam is materially better than another product when the tests were performed on foams of a different thickness. Dyplast believes that ISO-C1/2.0 represents leading edge technology and offers the most complete set of properties of any polyisocyanurate foam on the market;

• Other polyisocyanurate insulation manufacturers or suppliers may claim better flame and smoke spread results for "systems", which may include aluminum facers or metal laminates; customers should request flame/smoke data on the polyiso foams without laminates in order to credibly assess alternative insulation.
