Memtec Single Ply PVC roof membranes represent a modern, efficient, and cost-effective solution for flat roofing and waterproofing across domestic, commercial, and industrial projects.
With over 40 years of proven performance in the UK, Memtec’s range is engineered to deliver long-lasting protection, versatility, and ease of installation for virtually any flat roof application.
What Are Memtec Single Ply PVC Membranes?
Memtec membranes are high-performance, mesh-reinforced polyvinyl chloride (PVC) sheets designed to provide a durable, watertight barrier on flat roofs. These systems are suitable for new builds, extensions, refurbishments, and overlays on existing roofs, and can be used on a variety of substrates including timber, concrete, metal, and screeds.
Key Benefits
- Exceptional Durability: Backed by a 20-year product guarantee and British Board of Agrément (BBA) certification (Certificate No. 14/5144), Memtec membranes have a BBA-confirmed service life in excess of 35 years.
- Versatility: Suitable for all flat roof constructions-from small domestic extensions to large commercial and industrial buildings. Memtec membranes can be mechanically fixed, fully bonded, or loose laid and ballasted, making them adaptable to a wide range of project requirements.
- Weather and Fire Resistance: Memtec membranes are UV resistant, self-extinguishing, and rot-proof, with high resistance to ageing and root penetration. They maintain flexibility down to -25°C without cracking, ensuring performance in harsh UK conditions.
- Safe, Clean Installation: All laps and seams are hot air welded, creating strong, watertight joints without the use of naked flames or hot bitumen, reducing installation risks and environmental hazards.
- Aesthetic Flexibility: Available in standard dark grey and special-order light grey, Memtec membranes can replicate the appearance of traditional lead or zinc standing seam roofs using decorative profiles-offering both performance and visual appeal.
Product Range and Applications
Memtec offers a complete range of single ply PVC membranes and accessories to suit any flat roof scenario:
- Mechanically Fixed Systems: Ideal for large, open roofs or windy locations, these systems are secured with screws and washers for rapid installation and high wind uplift resistance.
- Fully Bonded Systems: Using cold-applied adhesives, these membranes provide a smooth finish and are perfect for projects where mechanical fixings are undesirable or the substrate is sensitive.
- Fleece-Backed Membranes: Designed for overlaying existing roofs, fleece-backed options offer enhanced puncture resistance and cushioning, making them suitable for refurbishment projects.
All Memtec membranes are mesh-reinforced for maximum dimensional stability and are vapour permeable, preventing blisters and bubbles. They are lightweight and fast to install, but must be fitted by experienced, trained professionals to ensure warranty compliance and optimal performance.
Sustainability and Cost Effectiveness
Memtec membranes are not only durable but also cost-effective, often providing significant savings compared to traditional lead or metal roofing systems. They are resistant to theft (having no resale value) and suitable for green roofs and roof gardens due to their root penetration resistance.
Accreditations and Guarantees
- BBA Certified: Service life in excess of 35 years (Certificate 14/5144).
- 20-Year Product Guarantee: Documented for peace of mind on every installation.
- NHBC Standards: Accepted for all flat roofs under NHBC Standards 2014.
