Lead is a material that, when applied to construction and building, has an excellent behaviour due to its characteristics: water-proofing qualities, corrosion resistance, malleability, sound-proofing capacity, incombustibility and ease of coupling and assembly. Another remarkable feature is lead resistance over time. Lead in the shape of sheets, as a roof or a dove covering, is atmospheric corrosion resistant because it creates a protection film in the contact of the oxygen and carbon dioxide of the atmosphere.

Lead plates for

water-proofing

Lead sheet is an extremely useful material for the construction of protection and water-proofing elements, particularly when attachment is necessary to existing structures, because it is when the material malleability is used to its maximum effect. It is currently used for the water-proofing of façades and roofs.
Examples
Roofs, cornices, terraces, balconies and gutters in order to ensure water-tightness of chimneys, dormer windows, door roofs, balustrades, as well as railings and rainwater drainpipes. It is also very used in the water-proofing of bathrooms, ponds and fountains.

Sound-proofing
Lead, due to its density and lack of rigidity, turns into a much more effective barrier against sound transmission than any other type of sheet used in construction. Lead is an excellent acoustic insulation, particularly at low frequencies.
Examples
Widely used in recording studios, radio and TV, discos and music bars, lead is most effective for the removal of the annoying noises produced by lifting equipments or collective heating equipments. It is also the definite solution for the soundproofing of shutter boxes and the elimination of any night noise.
