ROOFING AND WALL CLADDING SOLUTION

Redevelopment Project in the Norfolk Countryside

Our team was engaged to design a roofing and wall cladding solution for a prestigious redevelopment project set in the picturesque heart of the Norfolk countryside.

CHALLENGES AND SOLUTIONS

To meet the unique requirements of this project, we developed a tailored engineering solution for both radius and straight roofs, incorporating the following key elements:

• Structural Steel Decking: 1.50 mm thick, 600 mm wide, and 150 mm deep transverse-laid structural steel decking to form a robust base.
• Thermal Insulation: A 325 mm insulation quilt, achieving a U-value of no less than 0.18 W/m²K, significantly enhancing energy efficiency.
• Thermal Support Halters: Designed to support the outer cladding effectively while maintaining thermal performance.
• Standing Seam Outer Sheets: 0.90 mm thick pre-coated aluminium sheets, 400 mm wide and 65 mm high, providing a durable and aesthetically pleasing finish.
• Roof Lights: Glazed composite (aluminium and timber) opening roof lights integrated with specialist in-situ surround weathering for seamless durability and functionality.
• Radius Barge-Board Flashings: Fabricated from 3 mm thick welded and linished polyester powder-coated aluminium, ensuring a perfect fit and long-lasting protection.

WALL CLADDING DESIGN

For the wall cladding, we opted for a ventilated system that combined aesthetic appeal with practical performance:

• Material Choice: '3-inch' sinusoidal pre-coated aluminium cladding for a contemporary, sleek appearance.
• Ventilated System: Installed over OSB boarding, breather membrane, and counter battens, creating a ventilated air space for moisture control and thermal efficiency.

ADDITIONAL FEATURES

We also designed a roof balcony by overlaying the roof build-up with 2 mm thick, flat aluminium polyester powder-coated CNC pre-punched sections, incorporating intricate manifestation for a striking visual effect.

RESULTS

The project successfully balanced form and function, delivering:

• A roofing system with enhanced thermal performance and structural integrity.
• A wall cladding solution that is both visually striking and thermally efficient.
• Custom features such as roof lights and a balcony that integrate seamlessly into the overall design.
