USG SECUROCK Glass Mat Gypsum-Fiber Roof Board 1/2 in. x 4 ft. x 8 ft., Off-White
USG SECUROCK Gypsum-Fiber Roof Board is a high-performance, fiber-reinforced cover board for low-slope roofing systems, offered here in a 1/2 in. x 4 ft. x 8 ft. off-white panel. Its homogenous composition is strong and water-resistant through the core, so there is no facer to delaminate. One sell unit is a single panel, sized to pair under single-ply membrane systems.
Key Features:
- Homogenous composition: The fiber-reinforced panel is strong and water-resistant all the way through to its core.
- High wind uplift: The homogenous make-up achieves high wind uplift ratings with no risk of facer delamination.
- Adhered-system bond: Delivers low absorption and an exceptional bond in adhered single-ply systems.
- Moisture and mold resistant: The panel resists moisture and mold in demanding low-slope roofing environments.
- 97% recycled content: Manufactured from 97% recycled material, combining performance with sustainable design.
- Single-ply ready: Designed for use under single-ply roofing systems in low-slope applications.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
SECUROCK Gypsum-Fiber is a strong cover-board choice when wind uplift and facer delamination are concerns, since the board is consistent through its core. Match board thickness to the membrane manufacturer's cover-board requirements and verify attachment spacing for the project's wind zone. Its low absorption and strong bond make it especially well suited to adhered single-ply assemblies.
Handle panels with team lifts or mechanical equipment, wear cut-resistant gloves and eye protection when cutting gypsum board, and follow the membrane manufacturer's installation and wind-uplift requirements.
