FC Sleeves Flexible Roofing Sleeve Fasteners


Scope of Application

Specifically designed for the mechanical fastening of rock wool insulation layers and TPO/PVC waterproof membranes in single-ply roofing systems.


Technical Advantages

  • Forms a telescopic fastener unit with SW screws, preventing screw tips from penetrating the PVC/TPO waterproofing membrane

  • Dome-Shaped Disc Design: Mushroom-shaped disc distributes stress evenly and provides enhanced rigidity to resist bending

  • Eight-Grip Claw Structure: Eight claws firmly engage with the membrane's reinforcement layer, significantly increasing friction and preventing slippage

  • Universal Membrane & Insulation Fixing: Compatible with SW screws for both membrane and insulation attachment, offering flexible on-site configuration

  • The sleeve-screw combination effectively blocks heat transfer through metal screws, preventing condensation formation
