Marley Universal 125 Vapour Permeable Underlay 1Mtr x 50Mtr
A lightweight universal underlay for use on pitched roofs with tiles and slates.
The Marley range of underlays have a number of built-in features to help make installing a roof quicker and easier whilst still complying to all current roofing standards.
Easy to handle - supplied in 1m width rolls which are easier to handle than wider 1.5m rolls, especially on a roof in windy conditions.
Guidance lines for minimum laps - the printed guidance lines provide a visual reference to ensure sufficient lap to the British Standard and to ensure that the underlay is laid consistently and straight

To ensure maximum performance and quicker and easier installation, Marley roofing underlays feature an integrated tape system for sealing at the laps which:
Eliminates the need for a fly batten
Eliminates the need to increase laps to coincide with a naturally occurring tile batten
