What is 48kg Code 4 Roll of Milled Lead Flashing 390mm x 6m?

48kg Code 4 Roll of Milled Lead Flashing features a 390mm width and a standard 6m length, providing approximately 2.34m² of coverage per roll. 

With an approximate weight of 48kg, this roll is a popular choice for a wide range of general-purpose and detailed flashing applications on building exteriors that require reliable weather protection.


Precision-manufactured to meet the stringent requirements of BS EN 12588, the "Code 4" designation refers to its specific nominal thickness of 1.80mm and a corresponding weight of 20.41 kg per square metre. 

This lead flashing is produced through a milling process, which involves passing a cast lead slab through rollers to achieve a consistent thickness, fine grain structure, and a smooth surface finish.


Its fundamental purpose is to provide a durable, malleable, and completely waterproof seal at various junctions and intersections on building exteriors (such as roof abutments, around chimneys, in valleys, and over openings). 

This prevents water ingress, protecting the building fabric from moisture damage and contributing to the structure's overall longevity. It requires the use of patination oil after installation to prevent unsightly white carbonate staining on the lead and adjacent materials.

Applications

  • General Abutment Flashings: Commonly used for creating effective weatherproof seals where pitched roofs meet vertical walls (e.g., the side of a house, an extension, or a dormer).
  • Pitched Roof Valley Linings: A good width for forming durable and watertight valley gutters (the internal angle channel where two sloping roof surfaces meet) on many standard pitched roofs.
  • Chimney Flashings: Suitable for various chimney flashing components, including side flashings (both stepped for pitched roofs and straight for flat sections), and for front aprons or back gutters on small to medium-sized chimney stacks.
  • Window & Door Head Flashings: Provides ample coverage for creating effective weatherproof drips and seals above window and door openings in masonry walls.
  • Flat Roof Perimeter Details: Useful for dressing upstands and detailing edges on flat roofs of moderate size.
  • Dormer Window Details: Can be used for flashing the cheeks (the vertical side walls of a dormer window structure), aprons (the flashing section below the dormer window sill), and roof junctions of smaller dormer window constructions.
  • Cover Flashings: A practical width for cover flashings over upstands or existing flashings as part of a two-part system.


Benefits 

  • Exceptional Durability & Longevity: Offers an extremely long service life, often outlasting many other building components, due to lead's inherent resistance to corrosion, UV degradation, and atmospheric attack.
  • Unrivalled Malleability: Easily dressed, shaped, and formed by hand or with simple tools to fit complex contours, abutments, and intricate roof details, ensuring a perfect, weatherproof seal.
  • Proven Weatherproofing: Provides a completely impermeable barrier to water, making it highly effective in preventing leaks at critical building junctions across all types of roof coverings.
  • BS EN 12588 Compliance: Manufactured to a recognised British and European standard, ensuring consistent quality, precise thickness tolerances, and correct lead composition for roofing and construction applications.
  • Recyclable & Sustainable: Lead is 100% recyclable with a relatively low melting point, and lead flashing often has a high recycled content, making it an environmentally sound choice when responsibly sourced, installed, and eventually reclaimed.
  • Aesthetic Appeal & Tradition: Weathers over time to an attractive, traditional grey patina that complements a wide range of building materials, both historic and contemporary.
  • Noise Reduction: Due to its density, lead can also contribute to reducing noise transmission, such as rain drumming on a roof.
