2. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Sealection 500 spray foam R-3.8 (RSI-0.67) per inch. [12] a water-blown low density spray polyurethane foam that uses water in a chemical reaction to create carbon dioxide and steam which expands the foam. Flame spread is 21 and smoke developed is 217 which makes it a Class I material (best fire rating). Disadvantages: Is an Isocyanate.

3. Exterior insulation finishing system - Wikipedia

   In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.

4. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Spray foam insulation extruding from a duct. Spray foam (expanding foam in the UK) is a chemical product created by a chemical reaction of two component parts, commonly referred to as side A and side B. [ 1 ] Side A contains very reactive chemicals known as isocyanate. Side B contains a polyol, which reacts with isocyanates to make polyurethane ...

5. Polyurethane foam - Wikipedia

   en.wikipedia.org/wiki/Polyurethane_foam

   The so-called flexible polyurethane foam (FPF) is produced from the reaction of polyols and isocyanates, a process pioneered in 1937. [1] FPF allows for some compression and resilience that provides a cushioning effect. Because of this property, it is often used in furniture, bedding, automotive seating, athletic equipment, packaging, footwear ...

6. List of polyurethane applications - Wikipedia

   en.wikipedia.org/wiki/List_of_polyurethane...

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

7. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, [1][2] especially when buildings are heated by oil, natural gas, or coal-based electricity.
