KingProof PVR®
High-quality, polyester-reinforced, UV-resistant PVC roofing membrane.
Overview
KingProof PVR is a high-quality, polyester-reinforced thermoplastic PVC waterproofing membrane designed for exposed roofing applications. It combines excellent mechanical properties with long-term durability under harsh climatic conditions. KingProof PVR is UV-resistant, flame-retardant and stabilised to withstand both high and low temperatures. It is hot-air weldable, forming homogeneous, watertight joints without open flame, and can be mechanically fastened to the load-bearing substrate or installed in a vacuum roof system. A lightly textured surface improves slip resistance during installation and maintenance while providing an aesthetically pleasing finish. It is offered in a range of thicknesses to meet different project requirements.
Applications
- Roofs with complex geometry (flat, sloped or curved)
- Exposed flat and low-sloped roofs
- Vacuum roof systems
- Warm / compact roof constructions
- Cold / ventilated roof constructions
Advantages
- UV-resistant
- High wind-load resistance
- Excellent weathering and environmental resistance
- Strong joints achieved through hot-air welding
- Available in different thicknesses
- Suitable for exposed roofing applications
- Textured surface improves safety during installation and maintenance
- Recyclable, with a low carbon footprint
- No open-flame welding, enhancing safety during installation

Usage & Packaging
Grades PVR-1.2 / 1.5 / 1.8 / 2.0. Width 1.0 / 1.1 / 2.0 / 2.2 m depending on grade. Length 15-20 m depending on grade and width.
Roll area varies by grade/width/length combination (see packaging); allow 120 mm overlap (130 mm for 2 m widths).
KingProof PVR rolls must be stored in their original packaging, away from direct sunlight, in cool, dry, frost-free conditions and protected on site with tarpaulins. Store horizontally on a pallet and avoid placing pallets of rolls on top of one another.
