IKO Rubershield Pro is a 140g/m2 Type LR Breather Membrane conforming to the requirements of BS5534:2014 when installed within a ventilated cold pitched roof construction. It is BBA approved* for use within cold and warm unventilated pitched roof construction and for use within vertical application. Amongst other benefits, each membrane provides a barrier to minimise the wind uplift load, wind driven rain, snow and dust as well as transporting any unwanted moisture resulting from ingress through the primary roof coverage into the roof drainage system.
