Filcor - Structural Fill

Filcor (Expanded Polystyrene) is increasingly being specified for an ever-growing range of applications. The most common applications include use as a lightweight structural fill alternative to more traditional fill materials.

Features

  • A range of compressive strengths available
  • Lightweight and easy to handle
  • Available as standard sheets or blocks
  • Can be profiled to customer requirements
  • Provides a high degree of insulation
  • Flame Retardant (FR) properties

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.

Applications

Filcor can be used for a range of applications including lightweight structural fill and insulation. The product can be manufactured in standard sheet sizes or alternatively profiled to the installer’s exact requirements.

Standard sheet/block 2400mm long x 1200mm wide x required depth.

Each Filcor sheet/block can be manufactured to the required depth, with a minimum depth of 25mm and a maximum depth of 1200mm.

Additionally Cordek can supply an individual Hot Wire Cutter for hire.

Environmental facts about Filcor EPS

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

* Global warming potential (GWP) is a means of measuring the strength of different 'greenhouse' gases in the atmosphere and can be used to define the impact greenhouse gases have on global warming over specified periods of time. As an example CO has a GWP of 1 over 100 years. All other greenhouse gases HFC, CFC HCFC and methane are measured relative to CO2.
Filcor Recycling
Filcor is 100% recyclable. As a single polymer, Filcor is straightforward to recycle and is recyled into items such as replacement hardwood decking or garden furniture and coat hangers

Case Study

The Kia Oval - Peter May Stand

Cordek was asked to provide a lightweight structural fill solution to raise the height of the newly constructed terraces, thus enabling additional rows of seating to be added.
