The procedure for installing Filcor sheets/ blocks is straightforward but the following points should be adhered to:

  • Filcor should be positioned on a firm level surface, with joints between individual sheets/ blocks, staggered where possible.
  • If the depth of Filcor required exceeds the maximum individual sheet/block depth of 1200 mm, then further layers can be added to achieve the total depth required. It is suggested that each layer is installed perpendicular to the previous one in order to distribute load as equally as possible.
  • Where there is a requirement to cut the Filcor sheets/ blocks, this can be carried out using a fine toothed saw, or alternatively a hot wire cutter: consult manufacturer for hire service details.

Further information on the procedure for installing Filcor is provided in the Installation Guide, available for download from the manufacturer's website.


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. It is available in a range of grades to meet the requirements of BS EN 13163: 2012.

Features and benefits:

  • 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.
