Application

Used for refurbishment of old fibre cement and metal profiled roofs on factories, warehouses and other buildings to provide a new waterproof skin without removing the original roof sheets, improving insulation and maintaining daylight levels.

Description

The FILON Over-Roofing system provides a durable, lightweight, weathertight solution for the refurbishment of old roofs on factories, warehouses and fibre cement or metal clad buildings.

Comprised of opaque, profiled Glass Reinforced Polymer (GRP) sheets for the main roof areas and translucent GRP sheets for any rooflight areas.

Features and benefits:

  • Suitable for all kinds of profiled roofs including old fibre cement and metal profiled sheet roofs.
  • Sheets can be specified to match the profile of the existing roof, and are available with a matt finish as standard and in any colour.
  • By matching the existing roof profile and maintaining the original sheet cover width, sheets can be laid to accurately match existing rooflight openings without reducing the daylight area.
  • Fast, easy, cost-effective installation with sheets available in long lengths to reduce end laps.
  • As the original roof covering remains in place, work can usually be carried out with minimal disruption to operations within the building.
  • Minimal extra load on roof structure due to lightweight system and drying of existing roof.
  • Improved insulation by incorporating glass fibre quilt to upgrade thermal performance and energy efficiency, 25mm Profix spacer supplied as standard with 60mm version available.
  • No asbestos handling or disposal problems as asbestos is not removed.
  • Proven in use in hundreds of applications around the UK for various clients.
  • Meets relevant UK Building Regulations for fire safety when appropriate grade is selected. Tested to BS EN 13501 Part 5, BS 2782-0 Annex B Method 508A, and BS 476 Parts 3, 6, and 7.
  • Sheet weight options to provide durability guarantees ranging from 12 to 30 years.
  • All weather faces of opaque sheets include Filon Protect Anti-Glare, a highly durable UV protective layer which extends sheet life and reduces discoloration.
