BLM Rolled Lead Sheet Code 5 – 510mm x 3m
BLM’s Rolled Lead Sheet is manufactured to British Standard BS EN 12588 and made from 100% recycled raw material. The British Standard ensures the alloy used contains a minimum amount of Lead and the correct amount of trace elements. It also guarantees a consistent thickness (+/- 5%) and grain structure, so its performance can be accurately predicted to provide maximum lifespan for correctly fitted Lead Sheet used in construction.
Lead is produced to six standard Code thicknesses, The Code numbers were derived from the imperial weight of a piece of the Lead measuring 1 square foot. For example, Code 3 weighed 3lb per square foot. With the introduction of the British Standard, the emphasis changed to the thickness rather than its weight per area.
Weight: 25.40 Kg per m²
Thickness: 2.24 mm
Length: 510mm x 3m
• An effective weatherproofing material used in the construction industry
• On average lead sheet lasts three times longer than other man-made roofing products
• Lead sheet is the most recovered and recycled building material in use today.
• Low maintenance and low lifetime costs
• Health protection: Lead sheet also offers effective protection against radiation for workers and patients in the medical, dental and veterinary sector, research facilities and in the nuclear industry.
• Soundproofing: Due to its ability to deaden sound waves lead sheet is also effective as soundproofing.
• Lead installation is not affected by damp or cold weather conditions, thereby minimising project delays.
Construction: Lead sheet is widely used in the building and construction industries, and is an attractive, effective and traditional roofing material which provides long-term weatherproofing, either as sheeting or as flashing or weathering for chimney flashings, gutter and valley linings, roof apex caps and other weatherings. It provides a completely watertight seal preventing rainwater leaks and so avoids damp and rot in homes and all other types of buildings.
Recyclable and a low carbon footprint: Lead sheet is the most recovered and recycled building material in use today and can be used again and again without any loss of performance. Lead also has the lowest carbon footprint of all metals because the production process requires relatively low levels of energy.
Low impact on the environment: Its high recycling rate and long-term availability make lead sheet one of the most sustainable of all products. Lead sheet’s low melting point during the recycling process means it is very energy efficient. Recycling is very cost effective meaning a lower environmental impact compared to primary production and resulting in very low CO2 emissions. Equivalent manmade roofing products have a much shorter life span and often require the use of toxic adhesives to fix them in place. Most polymer/composite roofing materials are not recyclable and they are likely to be discarded via landfill or incineration.
