Vent3 Classic is a triple layer fabric, high performance breather membrane, made from high tensile spun bonded polypropylene layers, around a micro‐porous polypropylene film. Designed for use in a fully supported or unsupported tiled, slated or metal roof system. The high vapour permeability and waterproof nature of the membrane, combined with excellent tensile/tear strength and high wind uplift resistance make Vent3 Classic the professional’s choice as the ultimate breather membrane. It is equally suitable whether draped unsupported over rafters or laid directly over insulation. The outer layer forms the functional waterproof surface, the middle layer is the breathable waterproof membrane, and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof. The upper surface is Grey, printed with the trade name and head lap lines. Available in 1.0m and 1.5m widths as standard to conform easily to any typical roof configuration or the individual working practices of the installer.

Pitched RoofingMarley Clay Club feature tile
Marley feature tiles should only be used with roof pitches of 70° and below, bands of feature tiles should be confined to a maximum of four courses. These bands must then be separated by a minimum of four courses of standard Plain Tiles. These measures are designed to reduce the risk of water ingress and wind uplift caused by the reduced tile head-lap inherent with these tiles. Ridges, hips, valleys and verges are the most vulnerable points of any roof and therefore careful detailing in respect of feature tiles should be considered. It is advised that Feature bands of tiling should be avoided directly adjacent to Bonnet/Arris hips, valley tiles or verges. Feature tiles should terminate against a standard Plain Tile at least two tile widths away from detailing/fitting. To assist in maintaining a broken bond pattern Feature tiles are available in both standard tile and tile-and-a-half formats.
