Cavity Drainage Supplies Northern Ireland
Oldroyd Membranes and Accessories
The Oldroyd range of Cavity Drainage Membranes are manufactured in Norway under an ISO 9001 and ISO 14001 quality and environmental management system. They are produced from high-strength polypropylene using a special, temperature-controlled manufacturing process. This results in an exceptionally straight, tough membrane which does not suffer from the “banana-ing” and “rucking” which cause problems when installing other cavity drainage membranes.
