Filcor (Expanded Polystyrene) is commonly used as a lightweight material for forming openings and voids within concrete structures. The use of Filcor void formers reduces the weight of the structure when left in-situ or alternatively can be used for temporary applications as part of a formwork system.
The versatility of Filcor means that any shape, size or profile can be manufactured with relatively short lead times. In addition, a range of materials of increasing compressive strengths are available to meet the loading requirements of the application, whilst also providing the most cost effective solution.
Filcor can be used for a variety of void forming applications for the formation, shaping and positioning of openings to reduce the weight of concrete structures. The product can be manufactured in standard sheet sizes or alternatively profiled to the installer’s exact requirements.

Filcor complies with both BS EN 13163:2012 and BS EN 14933:2007
The manufacture of Filcor is a low pollution process. Steam is he key component and the water is re-used many times. There is no waste in the process as all cut offs or rejects are recycled.
Filcor is 98% air. This makes Filcor a uniquely resource-efficient material with small carbon footprint.
Filcor is HFC, CFC and HCFC free and Pentane is used as its blowing agent. Pentane has a low Global Warming Potential* (GWP) of less than five. (The EU does not register pentane as a substance hazardous to human health or environment.)
Styrene, used in the manufacture of Filcor, occurs naturally in many commonplace items including strawberries, beans, nuts, beer, wine, coffee beans and cinnamon
