Product Overview
116kg Code 5 Roll of Milled Lead Flashing in a 760mm width and 6m length, delivering approximately 4.56m² per roll.
Code 5 refers to a nominal thickness of 2.24mm, equating to 25.4kg per m², making it a heavy-duty grade suited to wider flashings and applications exposed to greater wind uplift or thermal movement.
At 760mm wide, this roll is suited to parapet gutters, wide flat roof coverings, cladding details, and large dormer weatherings.
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.
Features & Benefits
- Exceptional durability: Code 5 lead offers a proven service life exceeding many decades, resisting corrosion, UV degradation, and weathering.
- Heavy-duty specification: At 2.24mm thickness, Code 5 provides increased resistance to wind uplift and thermal expansion compared to lighter grades.
- Malleability: Despite its greater strength, Code 5 can still be dressed and shaped with hand tools to form complex roof details.
- BS EN 12588 compliance: Manufactured to exacting European standards with consistent thickness and composition.
- Sustainable material: Lead is 100% recyclable and frequently produced with high recycled content.
- Coverage efficiency: Each 116kg roll provides 4.56m² of flashing material, ideal for wide-area details.
Applications
- Parapet gutters: Provides reliable linings across wide parapet gutters.
- Flat roof coverings: Used to weatherproof large flat roof sections with continuous lead coverage.
- Cladding details: Suitable for vertical wall cladding and weatherproof finishes.
- Dormer roofs: Provides substantial coverage for dormer structures.
- Industrial weatherings: Used in large-scale applications requiring durability.
Installation Guidance
- Preparation: Ensure substrates are dry, sound, and free from debris.
- Fixing: Secure with lead wedges or clips, allowing for expansion and contraction.
- Lap joints: Provide minimum 150mm laps to maintain weatherproof integrity.
- Patination oil: Apply immediately after fixing to prevent staining and enhance appearance.
- Support: Provide adequate support beneath wider runs to reduce risk of fatigue cracking.
