Thermal insulation INSULFOAM® HB

expanded polystyrenerigid panelinterior

InsulFoam HB (Holey Board) is a high-performance insulation consisting of a superior closed-cell, lightweight expanded polystyrene (EPS) with factory-applied holes. InsulFoam HB is cut from the same high quality stock as our flat InsulFoam products and, when requested, will meet or exceed the requirements of ASTM C578, Type I, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. InsulFoam HB is typically provided with 6 or 8 holes per board. InsulFoam HB offers a long-term, stable R-Value and has excellent dimensional stability, compressive strength and water resistant properties. Uses InsulFoam HB is specifically manufactured for use in lightweight insulating concrete systems that consist of cellular concrete, vermiculite or perlite. InsulFoam HB is fully encapsulated in the insulating concrete, and usually serves as the primary insulation in a roof system. InsulFoam HB can also be installed in a stair-step fashion to aid in creating a sloped or tapered system. Consult local building codes and lightweight insulating concrete deck manufacturers for system requirements.
