What is 18kg Code 4 Roll of Milled Lead Flashing 150mm x 6m?
18kg Code 4 Roll of Milled Lead Flashing features a 150mm width and a standard 6m length, providing approximately 0.9m² of coverage per roll.
With an approximate weight of 18kg, this lightweight and manageable roll is particularly suited for detailed flashing work, forming soakers, and applications where narrower lead sections are required for effective 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 150mm width is specifically designed for detailed flashing applications and situations where narrower, precise strips of lead are essential:
- Soakers: A primary application, used to form individual soaker flashings that are interleaved between slates or tiles at abutments with walls, chimneys, or other roof penetrations, providing a concealed and highly effective weatherproof seal.
- Narrow Cover Flashings: Ideal for use as a cover flashing over soakers or narrow upstands where minimal width is necessary or preferred for aesthetic reasons.
- Window & Door Trays/Sill Flashings: Creating robust damp proof courses or weathering details beneath window and door sills to prevent water ingress at these vulnerable points.
- Damp Proof Course (DPC) in Parapet Walls or Masonry: Traditionally used as a durable DPC within masonry constructions such as parapet walls or at changes of level.
- Weathering Tops of Timber Elements: Providing a protective capping to the exposed tops of timber fence posts, gate posts, or horizontal timber rails to prevent water absorption and decay.
- Small Repairs & Intricate Detailing: Useful for patching small areas of existing leadwork or for forming complex shapes around minor roof penetrations.
- Linings for Small Gutters or Channels: Can be used to line narrow internal gutters or channels where appropriate.
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.
