Product Details

Weidun® 005 TPO Roofing Membrane stands for thermoplastic polyolefin, which is a type of single-ply roofing membrane material. It’s commonly used in commercial and residential roofing applications. TPO roofing is known for its durability, flexibility, and resistance to ultraviolet light and chemical exposure.

Uses

Weidun® 005 TPO Roofing Membrane is considered a good option for single-ply roofing systems due to its excellent physical properties, ease of installation and minimization of maintenance.

Advantages
  • Highly durable and resistant to punctures, tears, and impacts.
  • Excellent resistance to UV radiation, ozone, and chemical exposure, ensuring longevity.
  • Flexible, allowing for easier installation and adaptability to a variety of roof designs and shapes.
  • Heat-welded seams create strong bonds, enhancing the overall strength of the roofing system.
  • Recyclable, making it an environmentally conscious choice compared to some other roofing materials.
Storage and Handling

To prevent damage, support rolls on end in an upright position and store in a clean, dry location, covering as necessary to protect from environment damage. Monitor environmental conditions during storage.

FAQ’s

Frequently Asked Questions

Clear, honest answers about how our Product.

Does TPO membrane require a protective layer?
It depends on the TPO membrane type and application. TPO systems designed for exposed roofing generally do not require an additional protective layer because the membrane itself is intended for long-term weather exposure. For non-exposed applications, such as some basement waterproofing systems, an appropriate protective layer should be installed after the membrane is completed and inspected to prevent mechanical damage.
How much TPO membrane can be loaded in a full container?
TPO membrane loading depends on membrane thickness, roll dimensions, packaging method and container type. A full container can generally load more than 10,000 m², while larger container configurations can reach over 15,000 m². The final loading plan should be confirmed according to the selected specification and container type.
Does TPO membrane require a primer before installation?
No primer is normally required for standard loose-laid or mechanically installed TPO membrane systems. The membrane is positioned and the overlaps are joined by hot-air welding. Installation quality depends heavily on correct detailing and welding, so the work should be carried out by well-trained installers familiar with thermoplastic membrane systems.
How are TPO membrane overlaps joined?
TPO membrane overlaps are typically joined by hot-air welding to create a continuous watertight seam. Welding temperature, speed and pressure should be adjusted according to site conditions and membrane specification, and completed seams should be inspected carefully after installation.
Where is TPO membrane commonly used?
TPO membrane is widely used for exposed roofing systems and can also be supplied in configurations suitable for other waterproofing applications. Product selection should be based on whether the system is exposed or concealed, the substrate, fixing method and project detailing requirements.
