Transforming a Historic Hertfordshire Site with Gemello® Revive

Overview

A former Fluorocarbon site in Caxton Hill, Hertfordshire, has undergone a striking transformation. What once stood as an aging industrial structure is now a revitalised, energy-efficient space comprising modern offices and a warehouse, thanks to the innovative Gemello® Revive over-cladding system from SIG Building Solutions.

Installed by Roof-Link Industrial and Commercial and managed by Vista Contracts South East Ltd, this project showcases the power of sustainable refurbishment, strategic collaboration, and high-performance British-made building products.

The Challenge

The project team was tasked with modernising the former Fluorocarbon site without demolishing the existing structure, a move aimed at reducing environmental impact, preserving architectural heritage, and controlling project costs.

The Solution: The Gemello® Revive Over-Clad System

To meet these objectives, the team specified the Gemello® Revive system, a warrantied over-cladding solution that dramatically improves thermal performance and visual appeal without the need for demolition.

“Gemello® Revive’s competitive pricing and immediate availability were key factors in our selection, it allowed us to keep the project on schedule and within budget.” – Martin Lloyd, Director at Roof-Link Industrial and Commercial.

Key Benefits of Gemello® Revive

• Comprehensive Warranties for long-term peace of mind
• Enhanced thermal efficiency with U-values as low as 0.14W/m²K
• Design flexibility with multiple external profiles and finishes
• Non-fragility (Class B) with a projected 25-year lifespan
• Suitable for multiple sectors: industrial, retail, office, education, health, and leisure

Project Highlights

• 100 linear meters of Filon GRP rooflights supplied by Filon Products, matched to the new over-roof profile.
• Insulation by Superglass®, improving thermal performance using non-combustible glass fibre in a bespoke cavity system.
• Engineered bar and bracket spacer system, designed for structural integrity and energy efficiency.

Collaboration & Local Sourcing

This project exemplifies the power of partnership. SIG Building Solutions, along with supply partners Filon Products and Superglass®, ensured technical support, product quality, and reliable phased deliveries, all manufactured in the UK.

“Design collaboration is key to meeting project goals, our UK manufacturing ensures consistent delivery and product support throughout.” – Phil Tye, National Sales Manager for Gemello®.

Results

• Refurbished look with a clean, modern façade
• Significant energy savings through thermal upgrades
• Reduced embodied carbon, avoiding demolition waste
• Efficient installation process, praised by on-site teams

“The site now has a fresh look and far better thermal performance, installation was smooth, and the results are outstanding.” – Martin Lloyd.

Conclusion

The transformation of the Caxton Hill site is a benchmark for sustainable refurbishment. By using Gemello® Revive, the project preserved historical value, improved energy efficiency, and delivered a striking new exterior, all while supporting British manufacturing.

As the construction industry continues to prioritise sustainability, projects like this illustrate how existing buildings can be reinvented through innovation, collaboration, and smart material choices.
