Details for HY-THERM AP Roof Insulation

CAD Details for HY-THERM™ AP Roof Insulation Polyisocyanurante Roofing Insulation - Guide Spec (10KB PDF) HY-THERM AP Product Information Sheet (34KB PDF) HY-THERM AP Roof Insulation is a polyisocyanurate foam insulation board with specially formulated organic/inorganic facers. It is suited for use under gravel-surfaced, fully mopped built-up (with suitable coverboard), modified bitumen roofing (with suitable cover-board), single-ply and metal roof applications. Only available west of the Rockies.

Building Code Compliance

Complies with ASTM C 1289 Type II, Class 1. Meets IBC/IRC requirements for foam plastic insulation. Factory Mutual Approved — Subject to the conditions of Approval as a roof insulation when installed as described in the current edition of the FM Approval Guide.

**Not all product sizes are available in all regions.
^† 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.
^{† †} Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM PLAZAMATE insulation and for STYROFOAM HIGHLOAD 40, 60 and 100 insulation products) or at yield, whichever occurs first. Since STYROFOAM 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.
³ Expected results for foam pending confirmation using Long-Term Thermal Resistance (LTTR) - ASTM C1289 Annex method.
