| POLYMER GYPTEC™ GYPSUM AND TECTUM DECK FASTENING PRODUCT REPORT NO. 191210
Installation Guidelines
 |
A pullout test to determine the
integrity of the roof deck is required for all Polymer GypTec installations. |
|
Polymer GypTec fasteners should
be installed using a heavy duty variable speed screwgun. Installation at a low rpm is
recommended. |
|
Minimum recommended embedment
for Polymer GypTec fasteners is 1-1/2" into the deck material. The Polymer Gyptec
fasteners should never penetrate the underside of the deck. |
|
To install Polymer GypTec
fasteners into Tectum® deck, simply position and drive the fastener through
the plate into the deck. In Gypsum and some cementitous wood fiber decks, pre-drilling a
pilot hole is required. (Depending on substrate hardness, a 7/16", 1/2" or
9/16" pilot hole will be required.) The pilot hole should be 1/4" to 1/2"
deeper than the required embedment into the deck. |
|
Fasteners should be spaced using
a pattern specified by the insulation or membrane manufacturer. |
|
The fastener is fully seated
when the head is tight against the Polymer GypTec plate. The fastener should not be
overdriven as to cause the plate surface to deflect more than 1/16". |
|
Overdriven Polymer GypTec
fasteners will significantly reduce fastener and plate performance and/or cause the
fasteners to strip-out. Underdriven fasteners will not distribute the load over the plate
properly. |

NOTE: Test results were obtained under ideal laboratory
conditions. The integrity of individual roof decks can vary widely, and will have
significant impact on Polymer GypTec pull-out values. Appropriate safety factors should be
applied to pull-out test results, and fasteners should be spaced accordingly.
