2. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   It can be used as internal insulation : between studs, joists or ceiling rafters, under timber floors to reduce sound transmittance, against masonry walls or externally : using a rain screen cladding or roofing, or directly plastered/rendered, [24] over timber rafters or studs or masonry structures as external insulation to reduce thermal ...

3. 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]

4. Sound transmission class - Wikipedia

   en.wikipedia.org/wiki/Sound_transmission_class

   Installing absorptive insulation, for example fiberglass batts and blow-in cellulose, into the wall or ceiling cavities does increase the sound transmission class significantly. [14] The presence of insulation in single 2x4 wood stud framing spaced 16 inches (410 mm) on-center results in only a few STC points.

5. Foam glass - Wikipedia

   en.wikipedia.org/wiki/Foam_glass

   Foam glass with open pores absorbs sound and is used as a sound insulation material. Penetration loss can be around 28.3 dB in 60~400 Hz. Depending on the properties of the foam glass, it can be used as insulation material in various sectors of construction engineering, as well as in shipbuilding, chemical, cryogenic, and high-temperature ...

6. Glass fiber - Wikipedia

   en.wikipedia.org/wiki/Glass_fiber

   Bushings are the major expense in fiber glass production. The nozzle design is also critical. The number of nozzles ranges from 200 to 4000 in multiples of 200. The important part of the nozzle in continuous filament manufacture is the thickness of its walls in the exit region. It was found that inserting a counterbore here reduced wetting ...

7. Glass wool - Wikipedia

   en.wikipedia.org/wiki/Glass_wool

   Glass wool batt insulation. Glass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool.The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties.
