Alto Lead is a high performance low cost aluminium flashing suitable for use as an alternative to traditional lead in both flat and pitched roof applications.
Alto Lead is produced from sheet aluminium with a protective polyurethane
coating on top and a polyisobutylene adhesive on the underside. Finished with a dimpled profile this unique construction ensures that Alto Lead is waterproof,
durable and extremely malleable. The polyisobutylene adhesive ensures a strong permanent bond to all building materials without the need for a primer unless a surface is extremely unstable and forming a watertight joint requires no additional tape or sealant.
Alto Lead is extremely safe to use due to it’s light-weight construction and cutting and shaping is achieved with a knife or scissors that produce no sharp edges. Consequently installation is rapid and safe with no health and safety issues.
Alto Lead has a 15 year guarantee with a life expectancy in excess of 20 years.
Alto Lead does not look like traditional lead and has no re-sale or scrap value, ensuring that theft and vandalism are eliminated.

Installation :

Alto Lead can be installed and worked in any direction using a mallet, roller or by hand. Cutting is achieved with scissors or knife. Before fixing Alto Lead to any building material surface the protective paper should be left in place until the final shape and position is determined. The surface should also be clean and dry to achieve permanent adhesion.

If the building material surface is unstable then a bituminous primer should be applied.

Alto Lead should be dressed into the brickwork and sealed and any jointing detail should have a minimum overlap of 100 mm.
