McGuire FlexGuard PVC - McGuire Roofing Products

Raw materials

The membrane is formulated from high-quality polyvinyl chloride resins, plasticizers, stabilizers, and performance additives, including UV inhibitors and anti-aging agents, to provide long-term weathering resistance, enhanced chemical resistance, and flexibility.

Excellent Quality

The membrane exhibits excellent overall quality, combining consistent manufacturing, durable formulation, and proven performance characteristics that meet or exceed applicable industry standards. McGuire Flexguard PVC has excellent age resistance. It also maintains flexibility in-40c temperatures and does not become hard and brittle.

Convenient Construction

Roofing assembly is simplified with McGuire Flexguard PVC. It’s easy to weld, highly efficient, and provides strong seam connections with high peel strength for watertight sealing.

Product Type

Smooth (Category H)
Reinforced with polyester scrim (Category P)

Application Scope

The membrane is suitable for use in new construction and roef restoration applications over approved substrates, including steel, concrete, wood, gypsum, and existing compatible roofing systems, when installed in accordance with manufacturer requirements and project specifications.

Thickness (mil)	Width / ft.	Length / ft.
45	5, 6, 10	100
60	5, 6, 10	100
80	5, 6, 10	100

Enhanced chemical resistance
Can increase a building’s energy efficiency
Excellent heat weldability
Exceptional low-temperature flexibility
Highly resistant to punctures, UV, ozone and oxidation

Substrates must be clean, dry, smooth, and free of sharp edges, fins, loose or foreign materials, oil, grease, and other materials that may damage the membrane.
All rough surfaces that can damage the membrane shall be repaired as specified to offer a smooth
substrate.
All surface voids greater than 1/4” (6.3mm) wide should be properly filled with an acceptable fill material. McGuire FlexGuard TPO waterproofing membrane is installed as a continuous roofing or waterproofing layer on the roof. Rolls are over lapped (side laps and end laps) prior to heat welding the seam areas. Install the McGuire FlexGuard TPO in accordance with current McGuire FlexGuard TPO specifications, details and workmanship requirement
