Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. Polystyrene is naturally transparent, but can be colored with colorants. Uses include protective packaging, containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records.
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier. This material is light blue in color and is owned and manufactured by DuPont. DuPont also has produced a line of green and white foam shapes for use in crafts and floral arrangements.

The company's subsidiary British Gypsum, which was the UK operating arm of the company, operates as a subsidiary of Saint-Gobain, with five manufacturing sites in Britain as of 2012.
Polyisocyanurate, also referred to as PIR, polyiso, or ISO, is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. The starting materials are similar to those used in polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol. The resulting chemical structure is significantly different, with the isocyanate groups on the MDI trimerising to form isocyanurate groups which the polyols link together, giving a complex polymeric structure.
Olin Corporation is an American manufacturer of ammunition, chlorine, and sodium hydroxide. The company traces its roots to two companies, both founded in 1892: Franklin W. Olin's Equitable Powder Company and the Mathieson Alkali Works. Accidents at Olin chemical plants have exposed employees and nearby residents to health hazards.

Building insulation materials are the building materials that form the thermal envelope of a building or otherwise reduce heat transfer.
Rigid panel insulation, also referred to as continuous insulation, 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. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
A koozie (US) or stubby holder (Australian) is a fabric or foam sleeve that is designed to thermally insulate a beverage container, like a can or bottle.
Insulated siding is home siding that includes rigid foam insulation, fused behind the exterior surface of the wall, for the purpose of reducing energy consumption, increasing the insulation value of the wall system and improving the stability and appearance of the siding. Currently, insulated siding is commercially available as a type of vinyl siding.

UFP is an important link in the medical device supply chain and a valued outsource partner to most of the top medical device manufacturers in the world.
Foam glass is a porous glass foam material. Its advantages as a building material include its light weight, high strength, and thermal and acoustic insulating properties. It is made by heating a mixture of crushed or granulated glass and a blowing agent such as carbon or limestone. Near the melting point of the glass, the blowing agent releases a gas, producing a foaming effect in the glass. After cooling the mixture hardens into a rigid material with gas-filled closed-cell pores comprising a large portion of its volume.
The Grenfell Tower Inquiry is a British public inquiry into the Grenfell Tower fire, which killed 72 people and destroyed Grenfell Tower on 14 June 2017. It was ordered by Prime Minister Theresa May on the day following the fire.
