Dyplast's latest Customer Bulletin, 0717 - ISO-C1® Polyisocyanurate Insulation Flame Spread and Smoke Development, is another in a series of white papers aimed at providing our clients, engineers, contractors, fabricators, and friends with objective information on competitive products and on items that affect our industry.

Marketing literature for insulation products on the internet and in printed media often address the flame spread index (FSI) and smoke developed index (SDI) as measured in accordance with ASTM E84 or comparable standards. This updated (0909) Customer Bulletin provides factual, clarifying information concerning ISO-C1's FSI and SDI as well as other important points relating to the combustion properties of polyisocyanurate foam.
