Oldroyd Xv green, Xv20 green and Xv20 greenXtra
Polypropylene and TPO damp proof membranes for green roofs
Oldroyd Xv green
• Designed for use in turf roof construction.
When working on the roof, the unique 'X pattern' helps to provide a superior grip. The rubberised outer layer on both sides minimises slipping of the membrane on the roof during laying, providing further grip when laying the turf or sedum. It is also a much safer surface in wet or dusty situations.
Manufactured from high-grade polypropylene with a TPO* outer layer on both sides and a recycled inner core, Oldroyd Xv green is incredibly strong. In fact it is three times stronger than normal single layer membranes and the studs won't break or flatten whilst working on it. Oldroyd Xv green is available in a range of sizes ensuring rapid progress during construction.
Oldroyd Xv20 green
• Designed for pitched lightweight roof construction and minimal depth growing medium.
Oldroyd Xv20 green is a membrane with 20mm deep studs specifically for use where minimal soil depth planting is required, allowing pitched roofs of lighter construction to be used.
Manufactured from high-grade polypropylene with a TPO* outer layer, Oldroyd Xv20 green has a rubberised surface on both sides to provide an extremely tough non-slip, easy to use membrane. It also provides a large water reservoir to accommodate growing mediums that can thrive in a reduced soil depth.
Oldroyd Xv20 greenXtra
• Designed for extensive planting regimes, flat roofs, roof gardens, brown roofs and roof terraces.
Oldroyd Xv20 greenXtra is a durable perforated membrane with a 20mm deep stud designed specifically for use in green and living roofs. The studs collectively form a rainwater reservoir, providing water for the roof plantings which is useful in areas of low rainfall. The 8mm diameter perforations allow any excess water to drain away. Oldroyd Tp felt laid on top of the membrane ensures root aeration and provides a root barrier.
Oldroyd Xv20 greenXtra membrane provides water management for green and living roofs and contributes to a reduction in the rate of rainwater run-off. As part of the Oldroyd family of green roof membranes, Xv20 greenXtra is made from high-grade polypropylene with a TPO* outer layer. This creates a rubberised surface on both sides, providing an extremely tough non-slip membrane which is easy to use, even at low temperatures and around complex constructional details.
