Polymer GypTec

The OMG Polymer GypTec™ is a high-strength, glass-filled nylon auger fastener with a 1-in. head designed to secure insulation and single-ply membrane to gypsum and cementitious wood fiber (i.e., Insulrock, Permadeck, Tectum®, etc.).
The fastener is used with 3-in. GypTec plates for insulation attachment and 2-in. GypTec plates for membrane attachment. Available in lengths from 2.5-in. to 12-in.

Features & Benefits

Features & Benefits

  • Designed for increased pullout resistance and shear strength.
  • Made from glass-filled nylon, which eliminates corrosion and thermal bridging
  • Non-penetrating design. Fastener threads into the deck but not through.
  • Plate design locks onto the head of the GypTec fastener
Product Use

Product Use

Prior to job bid, contact OMG to perform a pullout test to determine drill bit size and the pullout values. Overdriving the fastener can cause damage to the insulation facer.

The OMG Polymer GypTec is Factury Mutual approved for insulation attachment only. See system manufacturer for membrane attachment requirements.
Installation at a low RPM is recommended. Minimum fastener embedment into the deck should be 1 1/2 in. (2 in. recommended). The Polymer GypTec fastener should never penetrate the underside of the deck.

OMG Polymer GypTec fasteners can be installed into some cementitious wood fiber decks without pre-drilling. A pilot hole is required for gypsum. Use a 7/16-, 1/2- or 9/16-in. drill bit as determined by pullout test results. Pilot holes must be a minimum of 1/2-in. deeper than embedment. Polymer GypTec fasteners should be installed using a heavy duty variable speed screw gun.
