Masons 45 x 11 x 1800mm Ventilated Roof Battens - Box of 50

A plastic, ventilated batten made from tough, non-absorbent polypropylene, and with a self-adhesive strip for convenient placement before nailing off. Ventilated battens are used to form a cavity, allowing the free flow of air and moisture and assisting with effective ventilation of a roof cavity. Their cellular construction is nonconductive, capillary action resistant, and dimensionally stable, and assists with reducing thermal bridging. These battens are robust with a high compressive strength, so they are effective packers. They are not suitable for use as structural battens.
