scope:

This specification covers the general requirements for faced thermal insulation boards composed of rigid cellular polyurethane or polyisocyanurate foam surfaced with other materials. Additional specific requirements are covered by the applicable specification sheet (see 1.2). The service temperature will vary depending on the facing materials and the application. These specifications do not cover cryogenic applications. For intended uses see 6.1.

The thermal insulation boards covered by this specification shall be of the classes and styles specified in the applicable detailed specification sheet.

HH-I-1972/1 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Aluminum Foil on Both Sides of the Foam. HH-I-1972/2 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Asphalt/Organic Felt, Asphalt/ Asbestos Felt or Asphalt/Glass Fiber Felt on Both Sides of the Foam. HH-I-1972/3 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Perlite Insulation Board on One Side of the Foam and Asphalt/Organic Felt or Asphalt/ Glass Fiber Felt on the Other Side of the Foam. HH-I-1972/4 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Gypsum Board on One Side of the Foam and Aluminum Foil on the Other Side of the Foam. HH-I-1972/5 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Perlite Board on Both Sides of the Foam. HH-I-1972/6 - Insulation Board, Thermal, Polyurethane or Polyiso- cyanurate, Faced with Mineral Fiberboard on One Side of the Foam and Glass Mat on the Other Side of the Foam.
