Features and Benefits

  • The majority of the FD product variants are covered by third party Loss Prevention Certification Board (LPCB) product certification. This represents both full BS EN ISO 9001 quality compliance and a guarantee that the products are fully representative of those actually tested.
  • Tested and certified installation variants of the FD are available to cover masonry walls, dry walls, batt walls and floors. These cover the majority of applications/supporting constructions that are required to maintain compartmentation.
  • All tested installation methods give at least a E120 classification,usually only limited by the wall construction used. This is extended to E240 when installed using a HEVAC frame in a masonry/blockwork floor or wall.
  • Sleeve and angle methods, HEVAC frame methods, cleat and drop rod methods and batt infill methods are available.
  • Some rarer installation applications are covered by assessment/test information to BS 476-20/22.
  • Minimum size 100mm x 100mm.
  • Maximum single section size 1200mm x 1000mm, available from the smallest size up to this in millimetre increments.
  • Multi-section configurations are available to specific customer requirements, but will be subject to BCA approval.
  • Standard construction is a fully welded galvanised steel case, which gives a casing leakage that complies with Class C ductwork leakage specifications.
  • Other combinations of galvanised mild steel, type 1.4016 (430) and1.4401 (316) stainless steels for the blades and case are available to specific customer requirements.
  • The FD has a strong and robust design to both meet the exacting fire testing requirements and be resilient to site handling. This is supported by sound production techniques which result in a quality product.
