Polyfoam™ Slimline Zero Membrane
BBA Agrément Certificate
Certificate type
A thermally bonded tri-laminate of polypropylene.
Application
For use as a separating and water flow reducing layer (WFRL) in inverted and green roofs.
For full application details please refer to BBA certificate 17/5454.
Description
A high performance, thermally bonded tri-laminate of polypropylene; spunbonded (outer layers) and microporous (inner layer).
Features and benefits:
- It is used in combination with Polyfoam Roofboards (specified separately) as part of the Polyfoam Inverted Roof System for inverted and green roofs.
- Improves the thermal performance of protected membrane flat roofs by reducing the amount of rain water flowing between the insulation and the waterproofing membrane.
- Improves the thermal performance of inverted and green roofs.
- Waterproof and water vapour permeable.
- Enables thinner insulation and less ballast to be used.
- BBA certified.
Technical characteristics:
- Water resistance: able to resist a 1.5 m-head of water.
- Consult manufacturer's literature for further details.
