InsulFoam Holey Board (HB) for Concrete Roof Insulation
InsulFoam Holey Board (HB)
Holey Board for Concrete Roof Insulation
InsuFoam HB (Holey Board) is an engineered insulation consisting of a superior closed-cell, lightweight expanded polystyrene (EPS) with factory-applied holes. InsulFoam HB is cut from the same high-quality EPS 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.
InsulRoof HB is typically provided with 6 or 8 holes per board. InsulRoof HB offers a long-term, stable R-value and has excellent dimensional stability, compressive strength and water resistance 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 stairstep fashion to aid in creating a sloped or tapered system. Consult local building codes and lightweight insulating concrete deck manufacturers for system requirements.
