HT-304 is a rigid closed cellular 4# nominal density polyisocyanurate that is manufactured in buns for fabrication into a variety of
shapes and sizes that include, but are not limited to: piping, fittings, saddle supports, curved-side-segments and many others.
HT-304 is the industry leading polyisocyanurate when it comes to k-factor. When you are talking insulation, thermal efficiency is at the top of the list for performance. HT-304 has a k-factor of 0.172 BTU-in/hr-ft2-°F aged 180 days @ 75°F. HT-304 is a great choice for saddle supports and other areas where compression resistance is needed.
