Description
S
ecurock
®
Gypsum-Fiber roof board is a high-performance roof board for use in low-slope roofing systems. Its unique,
fiber-reinforced, homogenous composition gives the panel strength and water resistance through to the core.
S
ecurock
Gypsum-Fiber roof board provides exceptional bond and low absorption in adhered systems and with its
homogenous composition achieves high wind-uplift ratings with no risk of facer delamination. Made from 95%
recycled material, S
ecurock
Gypsum-Fiber roof board combines superior performance with sustainable design for all
types of roofing systems including single-ply, fluid-applied, built-up, spray foam, metal and modified bitumen roofing.
Advantages
Exceptional Strength
Engineered to provide superior wind-uplift performance for a wide variety of roof assemblies.
S
ecurock
Gypsum-Fiber roof board has uniform composition providing enhanced bond strength of membrane
systems with no risk of facer delamination.
Fire Performance
Provides excellent fire performance and demonstrates exceptional surface burning
characteristics (ASTM E84 (CAN/ULC-S102) Flame Spread 5, Smoke Developed 0).
Moisture and Mold
Uniform water-resistant core ensures excellent moisture and mold resistance.
Scored a maximum "10" for mold resistance on ASTM D3273.
Versatile
Can be used as a component in single-ply, fluid-applied, built-up, spray foam, metal and modified
bitumen roofing.
Sustainability
Made from 95% recycled materials and has earned independent certification from Scientific
Certification Systems for this achievement.
Limitations
– S
ecurock
Gypsum-Fiber roof board is engineered to perform within a properly designed roof system. The use
of S
ecurock
Gypsum-Fiber roof board as a roofing component is the responsibility of the design professional.
– Consult roofing manufacturers for specific instructions on the application of their products to S
ecurock
Gypsum-Fiber roof board
– Weather conditions, dew, application temperature, installation techniques and moisture drive can have adverse
effects on the performance of the roof system and are beyond the control of USG.
– Keep S
ecurock
Gypsum-Fiber roof board panels dry before, during and after installation. S
ecurock
Gypsum-Fiber
roof board should not be installed during rains, heavy fogs and any other conditions that deposit moisture
on the surface of the board. Apply only as much S
ecurock
Gypsum-Fiber roof board that can be covered by final
roof membrane system in the same day. Avoid exposure to moisture from leaks or condensation.
– For re-roof or re-cover applications, existing roofing system must be dry throughout prior to application of
S
ecurock
Gypsum-Fiber roof board.
– Plastic or poly packaging applied at the plant to protect board during rail or other transit should be removed
upon receipt to prevent condensation or trapping of moisture, which may cause application problems.
– S
ecurock
Gypsum-Fiber roof board should be stored flat and off the ground with protection from the weather.
If stored outdoors, a breathable waterproof covering should be used.
– When applying solvent-based adhesives or primers, allow sufficient time for the solvent to evaporate to
avoid damage to roofing components.
– USG allows the bonding of cold mastic modified bitumen and torching directly to the surface. Consult with
the system manufacturer for recommendations on this application.
– USG recommends maximum asphalt application temperature for Type III asphalt of 455 °F when using
S
ecurock
Gypsum-Fiber roof board. Application temperatures above these recommended temperatures may
adversely affect roof system performance.
Installation
–
Refer to roof system manufacturer's written instructions, local code requirements and Factory Mutual Global (FMG)
and/or Underwriters Laboratories (UL) requirements for proper installation techniques.
– Use fasteners specified in accordance with above requirements. Install approved fasteners with plates into
the S
ecurock
Gypsum-Fiber roof board, flush with the surface. Fasteners should be installed in strict compliance
with the roof system manufacturer’s installation recommendations and FMG Loss Prevention Data Sheet 1-29.
Proper fastener spacing is essential to achieve wind-uplift performance.
