Warehouse Over-Clad

Location:
Swindon, UK
Building Type:
Industrial Warehouse (2580m2)
Project Timeline:
6 Weeks
System Used:
Garland R-MER® CLAD Overclad System

Background

This project was a collaboration with Garland and CBRE. The building is having a complete renovation internally and externally, including the new over-clad roof, wall cladding and complete internal re-fit. Our scope of works was to install a new over-clad system on the roof including new trimline gutters and RWP. The existing metal roof had severe corrosion with paint starting peal causing water ingress internally.

Challenges

• Ageing Metal Roof: Severe corrosion and water ingress were widespread.
• Thermal Performance: Poor insulation was driving excessive heating costs in winter
• Weather conditions: Due to the time of year we had constant battles with weather conditions including freezing conditions, rain and wind.

Solution: Garland Overclad System

Garland proposed the R-MER® CLAD Overclad System, which involves fixing a new high-performance metal profile over the existing roof, incorporating insulation and a waterproof membrane. This avoids costly tear-off while improving energy efficiency and durability.

System Components:

1. Spacer bar and bracket system to create a cavity
2. Mineral wool insulation to meet Part L Building Regulations
3. Steel profile sheeting in Plastisol-coated steel
4. High-performance waterproof membrane
5. Continuous ridge and eaves ventilation to prevent condensation

Installation Process

1. Survey & Design:
• Roof survey using drone
• Custom design tailored to the roof pitch and layout
2. Preparation:
• Cover existing roof lights with OSB board
• Clean existing roof of debris
• install waterproof membrane
• install galvanized top hat system for spacer bars to fix to
3. Over-cladding:
• Fitting of insulation between spacer bars
• Installation of new metal profile sheets
• Install ridge
• Install barge boards
4. Final Touches:
• Rainwater goods
• Roof hatch access
• Safety line system

Results

Conclusion

The Garland Overclad System offered Iron Mountain a reliable, cost-effective, and sustainable refurbishment alternative to full roof replacement. Its success in this case reinforces the system’s value for industrial clients seeking long-term protection with minimal disruption. All in all this was a great project to work on even with severe weather conditions loosing us almost 2 weeks work we still managed to complete on time and to a high workmanship standard. With this project being to Garland spec all Garland reports came back with positive feedback including our high workmanship standard and rate of progression.
