Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene. In recent years the expanded polystyrene composites with cellulose [39] [40] and starch [41] have also been produced. Polystyrene is used in some polymer-bonded explosives (PBX). [citation needed]
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized 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.
Below are some uses for plastics in the construction industry: Pipes for rain water, sewage, gas distribution, and organizing wires may be made of plastic. Cable insulation and insulating tape is usually made of plastic. Plastic may be used in flooring and roofing materials. Doors, window panels, and skylights may be made of plastic.
Stacked blocks of geofoam at a construction site. Geofoam is expanded polystyrene (EPS) or extruded polystyrene (XPS) manufactured into large lightweight blocks. The blocks vary in size but are often 2 m × 0.75 m × 0.75 m (6.6 ft × 2.5 ft × 2.5 ft).
Panels consisting of polystyrene core and paper overlaid with plywood skins were used in a building in 1967, and as of 2005 the panels performed well. SIP systems were used by Woods Constructors of Santa Paula, California, in their homes and apartments from 1965 until 1984. This work was the basis for John Thomas Woods, Paul Flather Woods, John ...
The choice of which material or combination of materials is used depends on a wide variety of factors. Glass wool and EPS (expandable polystyrene) were by far the most commonly used building insulation materials in 2022, followed by stone wool and rigid foams made of PUR (polyurethane) and PIR (polyisocyanurate).

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.
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.
