Rhenofol CV: the smart choice for flat roofs

When it comes to modern flat roofing systems, performance, durability, and aesthetics are key. Rhenofol CV is a PVC-P roofing membrane known for its strength, versatility, and ease of installation. Whether you’re specifying for a new build or refurbishing an existing roof, Rhenofol CV offers a reliable, long-lasting solution that’s both practical and visually sleek.

What Is Rhenofol CV?

Rhenofol CV is a reinforced PVC-P (polyvinyl chloride plasticised) membrane designed specifically for mechanical-fixing on flat and low-pitch roofs. Manufactured by FDT FlachdachTechnologie GmbH (part of Holcim Group), Rhenofol CV combines a polyester mesh reinforcement with high-quality plasticised PVC for optimal mechanical strength and weather resistance.

Typically applied as part of a mechanically fastened roofing system, Rhenofol is a quick and cost-effective membrane to install, especially on large-scale roofing projects.

Key benefits of Rhenofol CV

» Superior strength: Thanks to its internal polyester reinforcement, Rhenofol CV is highly resistant to mechanical stress, tearing, and foot traffic.

» Excellent weather resistance: It performs well in extreme weather conditions, including UV exposure, high temperatures, and freeze-thaw cycles.

» Fire safety: Classified to meet European fire performance standards, often rated Broof(t1) depending on the system configuration.

» Lightweight and flexible: Easy to handle on-site, with minimal structural load.

» Watertight and durable: Fully waterproof with high resistance to ponding water and root penetration when used in green roof setups.

» Sustainable: Many systems are recyclable and compatible with green building certifications like BREEAM or LEED. All factory waste is fully recycled during manufacture.

» Cost efficient installation: Quick and easy to mechanically fix to metal, concrete and over other membranes.

» Non-brittle: Formed using virgin PVC for a non-brittle, durable approach.

The applications of Rhenofol CV

Rhenofol CV is ideal for a wide range of commercial, industrial and large-scale residential roofing projects, including:

• Logistics centres and warehouses
• Office buildings
• Hospitals and schools
• Green roofs and blue roofs
• Refurbishments and overlays of old bitumen roofs

Rhenofol is a part of the fastest-growing single ply membrane sector and is experiencing a surge in popularity on large-scale buildings due to its speed of installation and cost-efficiency.

Installation and compatibility

Rhenofol CV is designed to be mechanically fixed to the roof structure using fasteners and plates or stress plates. It can be used over:

• Steel and timber deck constructions
• Concrete substrates (with a separation layer)
• Existing waterproofing membranes (in refurbishment projects)

The seams are hot air welded for a secure, seamless finish. It’s also compatible with a full range of accessories like corners, outlets, and prefabricated details to ensure full system integrity.

Green and other eco roofing systems

With its excellent root resistance (as per FLL testing), Rhenofol CV is a great base layer for green roofs, offering environmental benefits and helping regulate building temperature. It also works well under ballasted systems or solar panel installations, giving architects and engineers maximum design flexibility.
