2. 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 ...

3. 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.

4. Fiberglass spray lay-up process - Wikipedia

   en.wikipedia.org/wiki/Fiberglass_spray_lay-up...

   The resin and glass may be applied separately or simultaneously "chopped" in a combined stream from a chopper gun. Workers roll out the spray-up to compact the laminate. Wood, foam, or other core material may then be added, and a secondary spray-up layer embeds the core between the laminates. The part is then cured, cooled, and removed from the ...

5. Cellulose insulation - Wikipedia

   en.wikipedia.org/wiki/Cellulose_insulation

   Subsequent real world surveys have cellulose performing 20–30% better at reducing energy used for heating than fiberglass. Compared to closed cell, Polyurethane foam insulation (R=5.5 to 6.5 per inch), cellulose has a lower R-value per inch, but is much less expensive; foam has a higher cost per equivalent R-value.

6. 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 ...

7. Cementitious foam insulation - Wikipedia

   en.wikipedia.org/wiki/Cementitious_foam_insulation

   Cementitious foam insulation is a cement-based thermal and acoustic insulation, [1] with an R-value similar to that of fiberglass. [2] It is installed as a foam with a consistency like shaving cream, [2] or as pre-cast slabs. [3] The current cost is similar to that of polyurethane foams. [2] Unlike many foam-in-place polyurethane foams, it is ...
