2. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Spray foam is a type of insulation that is sprayed in place through a gun. Polyurethane and isocyanate foams are applied as a two-component mixture that comes together at the tip of a gun, and forms an expanding foam. Cementitious foam is applied in a similar manner but does not expand.

3. Rigid panel - Wikipedia

   en.wikipedia.org/wiki/Rigid_panel

   A multi-family residential building under construction with rigid panel exterior insulating sheathing. Rigid panel insulation, also referred to as continuous insulation, [1] can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR), and polystyrene, or from fibrous materials such as fiberglass, rock and slag wool.

4. Polyurethane foam - Wikipedia

   en.wikipedia.org/wiki/Polyurethane_foam

   An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.

5. 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. Polyurethane - Wikipedia

   en.wikipedia.org/wiki/Polyurethane

   Polyurethane foam (including foam rubber) is sometimes made using small amounts of blowing agents to give less dense foam, better cushioning/energy absorption or thermal insulation. In the early 1990s, because of their impact on ozone depletion , the Montreal Protocol restricted the use of many chlorine -containing blowing agents, such as ...

7. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   Insulation to resist conductive heat transfer uses air spaces between fibers, inside foam or plastic bubbles and in building cavities like the attic. This is beneficial in an actively cooled or heated building, but can be a liability in a passively cooled building; adequate provisions for cooling by ventilation or radiation [ 62 ] are needed.
