We are pleased to announce that Oldroyd have increased the minimum recycled content of some of the main cavity drainage membranes in their product range – as shown in the table below:
| Membrane | Previous minimum recycled content | New minimum recycled content |
|---|---|---|
| Oldroyd Xv Black | 40% | 56% |
| Oldroyd Xs | 40% | 56% |
| Oldroyd Xv 20 | 40% | 49% |
| Oldroyd Green Range (Green Roofs) | 40% | 49% |
| Oldroyd Gtx Range | 40% | 49% |
It should be noted that these are minimum recycled contents and that where quality and availability of recycled plastic allows, up to 70% recycled plastic may be used.
Oldroyd membranes are produced using a multi-layer process. This produces a membrane with a core layer containing recycled plastic that is sandwiched between two outer layers of virgin plastic (see microscope image on the right).
This multi-layer technology allows recycled plastic to be incorporated into the membrane without having a detrimental effect of product performance.
All calculations for the recycled content of Oldroyd membranes are carried out in accordance with the definition in section 7.1.1.1 of ISO 14021:1999 (Environmental labels and declarations).
Oldroyd cavity drainage membranes are used for a variety of waterproofing and drainage applications including basement waterproofing, tunnel lining, barn conversions and green roofs.
