2. Polyisocyanurate - Wikipedia

   en.wikipedia.org/wiki/Polyisocyanurate

   The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.

3. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Open-cell foam is porous, allowing water vapor and liquid water to penetrate the insulation. Closed-cell foam is non-porous, and not moisture-penetrable, thereby effectively forming a semi-permeable vapor barrier. (N.B., vapor barriers are usually required by the Building Codes, regardless of the type of insulation used.

4. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...

6. Owens Corning - Wikipedia

   en.wikipedia.org/wiki/Owens_Corning

   In 1939, the U.S. Navy Bureau of Ships made Owens-Corning insulation standard in new warship construction. Warship insulation, called Navy Board, was a permanent form-board insulation covered with woven continuous fiber cloth. Owens-Corning produced a prototype boat hull constructed of fiber glass-reinforced plastic in 1944. [11]

7. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   In a narrow sense, insulation can just refer to the insulation materials employed to slow heat loss, such as: cellulose, glass wool, rock wool, polystyrene, polyurethane foam, vermiculite, perlite, wood fiber, plant fiber (cannabis, flax, cotton, cork, etc.), recycled cotton denim, straw, animal fiber (sheep's wool), cement, and earth or soil ...
