IKO NON-BREATHER MEMBRANES

IKO-Pitched-Roof-Underlay-Top-Colour

IKO’s non-breathable roof underlays protect your cold ventilated roof space from wind-blown water, snow and dust. They are only suitable for use in cold ventilated pitched roof systems. Warm roofs, or roofs without adequate ventilation, require a breather membrane instead.
