Product Overview
Reinforced TPO waterproof membrane is a heat-weldable single-ply waterproofing sheet made of thermoplastic polyolefin resin with embedded polyester reinforcement. Compared with homogeneous TPO sheets, the reinforced structure delivers improved tensile strength, tear resistance, and puncture resistance, resulting in long-term, durable waterproofing performance.
Built to withstand UV exposure, weather aging and thermal deformation, the membrane maintains stable flatness under temperature changes and resists wind uplift and light foot traffic during construction and maintenance. It is widely used for waterproofing exposed flat, metal, and concrete roofs, as well as green roof systems, in industrial and commercial buildings.
Available specifications cover thicknesses of 1.2–2.0 mm, standard roll widths of 1.0 m / 2.0 m, and roll lengths of 20 m / 25 m. Custom sizes are available per production feasibility. Standard finishes are smooth white or light gray. Our team reviews project drawings solely to confirm production capability, without providing engineering design or performance certification.
Product Features
1. Internal polyester reinforcement
A layer of polyester fabric grid is embedded within the membrane body during production. This internal reinforcement provides high tensile strength, tear resistance, and puncture resistance, making the membrane suitable for mechanically fastened roofing systems where wind uplift resistance is required.
2. Weather and UV resistance
The TPO base material offers resistance to weathering, ultraviolet radiation, and aging. The material remains flexible at low temperatures and maintains mechanical strength at elevated temperatures. Light-colored surfaces also reflect solar radiation.
3. Heat-weldable seams
Adjacent membrane sheets are joined by hot-air welding to form integrated seams. The sealing performance of welded joints relies on proper on-site welding workmanship and complete system detailing.
4. Dimensional stability
The internal reinforcement reduces the membrane‘s dimensional change under temperature fluctuations. This helps the membrane maintain its position and coverage during thermal cycling, reducing stress on seams and fasteners.

FAQ
Q1. What is the difference between reinforced and homogeneous TPO membrane?
Reinforced TPO has a polyester fabric grid embedded inside, providing higher tensile, tear, and puncture resistance. Homogeneous TPO has no reinforcement and is typically used for flashings and detail work.
Q2. What thickness should I choose for my roofing project?
Thickness selection depends on wind uplift requirements, roof traffic, and project specifications. Refer to your project‘s structural and wind load calculations for specific guidance.
Q3. How are membrane seams sealed?
Seams are joined by hot-air welding to fuse two sheets into an integrated joint. Final joint sealing performance depends on qualified on-site welding execution and system detailing.
Q4. Can the membrane be installed directly over existing roofing?
This depends on the condition of the existing roof and the project design. A qualified roofing contractor should assess the existing substrate before installation.
Q5. Is the membrane suitable for exposed outdoor applications?
Yes. TPO membrane is designed for direct exposure to weathering and UV radiation. The light-colored surface also reflects solar heat.
Q6. What is the low-temperature flexibility of the membrane?
The membrane remains flexible at temperatures as low as –40°C under laboratory test conditions for the material. Actual on-site flexibility and constructability shall be evaluated by your project engineer according to local climate.
