Rolled Lead Sheet – The Complete Manual eBook. The Manual is also available in an electronic format as a PDF flip-page e-book. It contains all of the up-to-date technical information you need to specify or install Rolled Lead Sheet manufactured to BS EN To minimise this, all rolled lead is manufactured to meet BS EN , with different lead codes (thicknesses) having different applications and weight. Another factor of meeting the standard is that the thickness of roofing lead may only have +/- 5% variance across its entire length. Our Basic Fitting Guides are designed to assist installing Rolled Lead Sheet in a range of roofing applications, including flashings, valleys, gutters and flat roofing.
Lead sheet, one of the oldest and most durable roofing materials, has been known to last for over years. However, even with the best of materials, poor design often leads to failure.

As well as Enviro Lead for roofing and cladding, JMR can provide decorative lead in the form of . Patination Oil should be used on lead roofing, flashings and cladding to give a uniform, attractive appearance where the lead is visible. The oil includes compounds designed to remove light oxide staining to produce a clean metallic surface on application. It is also necessary when water flowing from the Lead Sheet surface may come into contact /5(55).
