Increased Recycled Contents for Oldroyd Cavity Drainage Membranes

3rd April 2008 - 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:

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.
