As a 160g/m² membrane, this universal Vapour Permeable Underlay encapsulates a multitude of advantages aimed at facilitating consistency throughout its installation while meeting the British Standard guidelines. It boasts an integrated tape system that not only ensures convenient sealing of underlay laps but also serves as an efficient wind barricade, proving effective in all UK wind zones (BS 5534).
Made through a multi-layer bonding process involving laminates, this underlay stands as an exceptionally sturdy, durable and easily installable under-tile layer, versatile for both warm and cold roof applications. Thanks to the printed guidance lines, it offers a visual reference to ensure adequate lap alignment with the British Standard and provide consistently straight laying of the underlay.
Eliminating the need for extra 'fly' battens to secure laps or increased laps to coincide with tile batten courses, this universal Vapour Permeable Underlay effectively reduces costs, saving you time and money during installation. It can seamlessly integrate with the comprehensive Marley roof system or effortlessly complement tiles and slates from various manufacturers.
