This lead is rolled (or milled) which is of higher quality than cast and therefore conforms to BS EN 12588 : 2006. The Code 4 Lead Roll is considerably more flexible and resistant to wear when compared to the older Code 3 option due to its increased gauge making it a suitable choice for almost every type of pitched roofing including vertical cladding, dormer roofs and cheeks, as well as a variety of flashings (such as hip, ridge, chimneys, apron, and cover ones). These Code 4 Lead Rolls are 1.8 mm thick (which is an increase of 36%) and weigh 20.41 kg per square metre. This extra thickness means additional resistance to thermal movement which enables you to increase the maximum length of flashing by 50%. While the most popular sizes of this particular roll of lead are the Code 4 Lead 240mm x 6m and the Code 4 Lead 300mm x 6m. Lead has been a common choice of building material for centuries and is more popular than ever in modern times. If lead is correctly installed, then no other metal can match its longevity and protection properties. Features: Been in use as a building material for centuries.
