Expert Verdict — Reviewed by the SuperArbor Pro Desk
On gypsum and lightweight insulating concrete decks, fastener selection drives wind uplift performance, so choose the coated twin loc-nail over uncoated alternatives in these substrates. Use the shorter 1.4 in. fastener for base sheet alone and step up to 1.8 in. when attaching thicker insulation or recovery board. Always verify the fastening pattern against the specified wind uplift design.
Wear eye protection and gloves when driving fasteners with powder-actuated or screwgun tools.
