Fastener Polymer GypTec

fastener polymer gyptec is a glass-filled nylon auger fastener

Fastener Polymer GypTec is a glass-filled nylon auger fastener used to attach Sarnafil® S 327 Membrane or Sikaplan® Fastened Membrane as well as Sarnatherm® insulation, Sarnatherm roof boards, gypsum roof boards, or other Sika approved boards into cementitious wood fiber or gypsum roof decks.

  • Designed for increased pullout resistance and shear strength.
  • High tensile strength.
  • Made from glass-filled nylon, which eliminates corrosion and thermal bridging
  • Non-penetrating design.  Fastener threads into the deck but not through
  • The Fastener Polymer GypTec is FM approved for insulation attachment only.

Application

Application steps

APPLICATION

The Fastener Polymer GypTec can be installed into some cementitious wood fiber decks without predrilling.  A pilot hole is required for gypsum decks.  Use a 7/16, 1/2 or 9/16" drill bit as determined by pullout test results. Pilot holes must be a minimum of 1/2" (13 mm) deeper than embedment.  

Fasteners should be installed using a heavy duty variable speed screw gun. Installation at a low rpm is recommended.  Minimum fastener embedment into the deck should be 1-1/2 - 2" (38 - 51 mm) is recommended and required on FM insured decks.  

Care must be taken to not damage the roof deck and should never penetrate the underside of the deck.  Choose the correct fastener length and do not overdrive or underdrive the fastener.  Pullout tests are required prior to job start for technical evaluation.
