FM 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

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

• Features a thickened disc with integrated reinforcement ribs at the disc-tube junction, significantly enhancing bending resistance and overall stability

• 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
