Lead lasts.
In fact, it lasts much, much longer (centuries, in fact), than other materials that could be considered as its substitutes. Its fail rate is negligible and its resistance to corrosion by the atmosphere means that Lead Sheet will outlast any alternative building materials.
A contractor supported by the Lead Sheet Association's technical officers will have the experience to identify potential design faults that could result in failure at some future time and be able to suggest modifications that ensure problems are avoided.
Furthermore, the Lead Contractors Association now offers a 25 years guarantee of workmanship and materials for projects over £2,500 in value. Significantly, if current performance is anything to go by, alternative materials may well have already failed within 25 years!
So while Lead may at first appear marginally more expensive, in terms of longevity and ecology, (a significant factor in the light of possible future eco-taxes on building materials) it offers best value, and of course, also has a far greater aesthetic value.
Innovation keeps lead ahead
The Lead Sheet Panel System designed by architects Michael Hopkins & Partners is a revolutionary design solution that is in line with the recent trend towards fast track construction and non-scaffolding projects. The system allows panels to be fully pre-formed on or off site and then kept in storage until needed for installation. Experience has shown that it is possible to install up to a hundred panels a day. The integrated design simplifies the process and ensures a uniformity of finish.
Recent architectural projects using the system include the new Opera House at Glyndebourne and the Nottingham Inland Revenue Centre that needed 8,860 panels weighing up to 200kg each. The speed of construction and the stunning visual impact has opened up new ways for Lead to lead the way in modern buildings.
Lead has also become a viable solution for flat roofs, previously notorious for their water penetration problems. Lead is used as a roofing membrane because of its proven longevity then it is surmounted with lightweight roofing panels with a cement-like upper surface and water resistant extruded polystyrene backing for high thermal insulation value. The result is an attractive looking roof with an expected life that is 4 times that of existing flat roof systems.
