18kg Code 4 Roll of Milled Lead Flashing 300mm x 3m

18kg Code 4 Roll of Milled Lead Flashing in a 300mm width and 3m length, delivering approximately 0.9m² of coverage per roll.Code 4 refers to a nominal thickness of 1.80mm, equating to 20.41kg per m², making it the standard grade for general-purpose flashings that balance strength with workability. At 300mm wide, this size is suited to chimney aprons, back gutters, and wide cover flashings. The 3m length is convenient for repair jobs or projects requiring smaller, manageable sections.Manufactured to BS EN 12588, the milling process produces uniform thickness, fine grain structure, and a smooth finish for reliable installation. Its purpose is to provide a malleable, durable, and completely waterproof seal at critical junctions - including abutments, chimneys, and parapets - preventing water ingress and extending the lifespan of the building fabric. Application of patination oil after installation is essential to prevent carbonate staining.
