Trade Top Sheet 1 x 10 Metre Green
IKO trade top sheet green mineral surfaced is used as an underlay as part of a multi-layer system or as a single layer for shed/hutch roofs. It is cost effective roofing solution suitable for a wide range of projects, although it is not recommended for use on habitable buildings. This type of traditional roofing felt is composed of a fibre base saturated and then coated with bitumen and surfaced with either sand or a slate finish. Used as a single, two-layer or three-layer application, these products are for use as temporary waterproofing or for use on sheds or garden buildings.

• Nail fixing, cold adhesive or pour and roll hot bitumen application
Where applicable, Fibre Based Roofing membranes should be installed in accordance with the relevant sections of BS 8217: 2005, Code of practice for reinforced bitumen membranes for roofing' and to IKO's specifications. If applied by traditional pour and roll methods, hot bitumen is poured (or applied by a mop) in front of the roofing felt roll, which is then unrolled into the bitumen, spreading it to give a continuous coating for the full width. The membrane is applied with minimum 75 mm side and end laps. Built-up systems can equally be formed using IKOpro HP Cold Adhesive: however the general bonding principles still apply. Where using Fibre Based Roofing in a built-up system to a garage or outbuilding, it is typically installed in a two or three layer system. In a two-layer system both layers should be fully bonded, the underlay being bonded to a suitable substrate. In a three-layer system the cap sheet and intermediate layers should be fully bonded to a random nailed, or partially bonded, preparation layer depending on the substrate. Detailed specification advice is available from the IKO Technical Services Department. Where used as a single layer on a shed roof, the minimum pitch of the roof should be 20 degrees. Fibre Based Roofing should be nail fixed with the laps fully sealed in IKOpro HP Cold Adhesive.
