Coming Soon To Greengates Builders Merchants, Lancashire: LEAD-FREE

LEAD-FREE is a high performance low cost aluminium flashing suitable for use as an alternative to traditional lead in both flat and pitched roof applications.

 LEAD-FREE 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 LEAD-FREE 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.

 LEAD-FREE is extremely safe to use due to its lightweight 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.

 LEAD-FREE has a 15yr guarantee with a life expectancy in excess of 20yrs.

Installation: LEAD-FREE can be installed and worked in any direction using a mallet, roller or by hand. Cutting is achieved with scissors or knife. Before fixing LEAD-FREE 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 Cromar bituminous primer should be applied. Any jointing detail should have a minimum overlap of 100mm.
