Increased Recycled Contents for Oldroyd Cavity Drainage Membranes
– 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 mimumum recycled content||New minimum recycled content|
|Oldroyd Xv Black||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 188.8.131.52 of ISO 14021:1999 (Environmental labels and declarations).
