+353 18 023333 www.necoflex.ie

A breathable polypropylene pitched roof underlay used to reduce wind load on slates and tiles, and to provide a secondary water-shedding layer against wind-driven rain or snow and has been designed specifically to meet the performance requirements for a pitched roof underlay.

It is manufactured by laminating a plastic film between two polypropylene fabric layers to form a breathable waterproof membrane. Combines excellent tensile strength characteristics with high puncture and nail tear resistance. It is also are resistant to UV light degradation, but is not designed to be left exposed for long periods and must be covered as soon as possible.
