AluFlash lightweight flashing

AluFlash is a flexible, environmentally friendly alternative to lead as a weathering flashing material for buildings. It is aluminium based and available in two unique surface finishes depending on the application. The lead-free embossed finish is designed for applications requiring less complex shapes such as pitched roof valleys, secret gutters, soakers for slates and double lap tiles and box gutters.

The cross corrugated finish allows up to 25% extensibility and is designed for use where the flashing has to be moulded over and around complex shapes such as profiled roof tiles and corner junctions. It is available in 5m rolls in 150, 200, 250, 300, 350, 400, 450, 500 and 600mm widths

AluFlash is also available factory fitted to all Glidevale brick and blockwork abutment trays and horizontal cavity trays.
