ISOCASTâ„¢ R Insulation features a thermally efficient polyisocyanurate foam core with trilaminate facers on both sides. It is designed for use in concrete sandwich panels where it is sandwiched between two layers of concrete with connectors holding the finished panel together.
The trilaminate (aluminum/poly/kraft) facers make ISOCASTâ„¢ R Insulation virtually moisture resistant. Because it has no exposed metal facings, ISOCASTâ„¢ R Insulation will not corrode or react chemically with the concrete in sandwich panel applications. In addition, the insulation offers economical thermal performance under the harsh vapor drive conditions often exhibited in precast concrete panels in cold climates.
Building Code Compliance
Complies with ASTM C1289 Type I, Class 1. Meets IBC/IRC requirements for foam plastic insulation. See ICC-ES NER-616. FM specification tested.

(1) Not all product sizes are available in all regions. (2) R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2• h•°F/Btu. R-value determined by ASTM C518. (3) Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM™ Brand PLAZAMATE™ Insulation and for STYROFOAM™ Brand HIGHLOAD 40, 60 and 100 Insulation products) or at yield, whichever occurs first. Since STYROFOAM™ Brand Extruded Polystyrene and Dow polyisocyanurate insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep. For static loads, 3:1 is suggested. For dynamic loads, 5:1 is suggested. |
