What is 37kg Code 4 Roll of Milled Lead Flashing 300mm x 6m?

37kg Code 4 Roll of Milled Lead Flashing offers a versatile 300mm (approx. 12 inches) width and a standard 6m length, providing approximately 1.8m² of coverage per roll. 

With an approximate weight of 37kg, this roll is perfectly dimensioned for a vast array of common and essential flashing applications, delivering robust and reliable weatherproofing.


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. 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

The 300mm width is an industry-standard dimension, making this Code 4 lead flashing highly versatile and suitable for many crucial weatherproofing details:

  • Standard Cover Flashings: Widely used for creating visible cover flashings at abutments where pitched roofs meet vertical walls, or for capping parapet walls or string courses.
  • Pitched Roof Valley Linings: A common and effective width for forming durable, watertight valley gutters on a variety of pitched roof designs.
  • Chimney Flashings: Suitable for all standard chimney flashing components, including front aprons, side flashings (both stepped for pitched roofs and straight for flat sections), and back gutters for typical domestic chimney stacks.
  • General Abutment Flashings: Providing reliable weatherproofing for junctions between different roof sections, or where pitched or flat roofs meet vertical structures such as dormer cheeks or gable walls.
  • Saddle Flashings: Creating weatherproof seals at the apex of a roof where it abuts a vertical surface, such as a chimney stack or adjoining wall.
  • Dormer Window Details: Ideal for flashing the cheeks (the vertical side walls of the dormer structure), aprons (the lead flashing fitted below the dormer window sill where it meets the main roof slope), and the flat or pitched roof sections of standard-sized dormer windows.
  • Bay Window Roofs: Flashing the complex junctions and angles found on traditional bay window roofs.
  • Flashings over Window and Door Heads: A suitable width for providing protection above openings in masonry walls.


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.
