Lead Cladding for Towers: Vertical Detailing & Heritage Guide
Lead is not just for roofs — it is also an excellent material for vertical protection. Correctly detailed lead cladding for towers provides weathering, durability and a distinctive heritage finish. This guide covers bay setting-out, joints, fixings and decorative integration in line with Leadwork Standards.
1. Code Selection
Vertical cladding requires durability. Code 6 is standard, with Code 7 often specified on exposed sites or tall towers subject to wind pressure.
2. Bay Setting-Out
Cladding should be divided into vertical bays no wider than 1 m. Wood-cored rolls or standing seams separate bays, providing both movement and visual rhythm.
3. Fixings & Support
Lead cladding is fixed to timber boarding or metal substrates. Fixings must allow for thermal movement. Clips, not nails through the sheet, secure lead at edges and joints.
4. Architectural Integration
Cladding should align with window heads, cornices and string courses for a cohesive architectural finish. Decorative rolls or bosses may be used to echo building symmetry.
5. Finishing & Maintenance
Apply patination oil to visible surfaces. Inspect regularly for joint integrity, particularly where vertical cladding meets roof coverings.
FAQs
What lead code is best for tower cladding?
Code 6 for most cases, with Code 7 for tall or highly exposed towers.
How wide should bays be?
No wider than 1 m. Narrower bays may be required for complex tower geometry.
How is lead fixed vertically?
With clips that allow for movement, not nails through the sheet. Sheets are dressed over secure substrates like timber boarding.
Can lead cladding be decorative?
Yes. Rolls, bosses and moulded details can enhance the architectural character while remaining functional.
Does vertical leadwork need patination oil?
Yes. Patination oil prevents staining on adjacent masonry and ensures even weathering.
