See our recent project: External Wall Insulation in Winchester. Commercial buildings in the UK face a major challenge: meeting modern energy-efficiency standards while maintaining a professional, welcoming appearance. We recently completed a large-scale External Wall Insulation retrofit at the Job Centre in Winchester, transforming a tired, weathered exterior into a clean, high-performance facade.
External Wall Insulation in Winchester
Before we arrived, this building was showing clear signs of neglect. Years of exposure to the elements had left the original facade looking stained and weathered. More importantly, like many commercial buildings of this era, the building was losing significant heat through the fabric of the walls. The client needed a solution that would address both aesthetic issues and thermal inefficiency in one go.

Precision-Engineered EWI
To bring this building up to modern standards, we implemented a full External Wall Insulation (EWI) system using industry-leading materials.
| Feature | Specification |
| System | External Wall Insulation (EWI) |
| Material | EWI Pro System |
| Finish | Silicone Render |
| Colour | Antique White |
| Surface Area | 120m² |
By wrapping the entire 120m² facade in an EWI Pro system, we’ve created a continuous thermal barrier. This doesn’t just make the building look brand new – it’s now protected by a high-grade, water-repellent finish that will stay “Antique White” and clean for years to come, regardless of the British weather.
