FT Sleeves Flexible Roofing Sleeve Fasteners


Scope of Application

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


Technical Advantages

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

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

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

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