EPSgebouwenonderdelen

EPSgebouwenonderdelen are building components made from expanded polystyrene (EPS), a rigid, closed-cell foam used primarily for thermal insulation and lightweight construction. EPS is produced by expanding polystyrene beads with steam and fusing them to form boards, blocks, or cores for panels.

Common types include insulating boards and blocks, EPS cores in sandwich panels (for example with cementitious or gypsum facings), insulated wall and roof panels, and decorative or functional elements such as profiles and cornices that incorporate an EPS core. EPS-based components are also used in insulating concrete formwork (ICF) systems and in prefabricated façade elements.

Applications focus on improving thermal performance in walls, roofs, and floors, often within prefabricated building systems. EPS cores are used in sandwich panels, as formwork for poured concrete, or as lightweight insulating infill in various structural assemblies.

Key properties include low thermal conductivity (typical grades around 0.030–0.040 W/mK), light weight, and ease of machining and installation. EPS is moisture resistant when dry but can be affected by prolonged exposure to water, so appropriate protective finishes and detailing are important. In fire performance, EPS is combustible and commonly requires fire-retardant additives and protective coating or separate fire-rated layers to meet local regulations.

Manufacturing and sustainability considerations cover production from polystyrene beads, with products available as boards, blocks, or laminated panels. EPS is recyclable through mechanical recycling and regranulation, and some waste streams can be reused in new EPS products; however, coatings and adhesives can influence recyclability. Products are typically specified and installed in accordance with relevant European and national standards for insulation materials and fire safety.
