INCA Case Study: Brize Norton MOD

Introduction:

We recently completed this programme of EWI works across 59 properties in Brize Norton, aimed at significantly improving energy efficiency and thermal comfort for the residents. Working closely with and on behalf of Anglian Building Products, our team delivered the upgrades with minimal disruption, ensuring high-quality standards and long-term benefits for the local community.

Properties & Specification:

• 1-52 Abingdon Road
• 1-6 Feltwell Close
• 1-28 Innsworth Road

These industrial-looking properties were comprised of a concrete substrate and finished off with a pre-cast concrete exterior, featuring reema panels on the first floor and fluted panels on the second.

The specification outlined a Wetherby 90mm Epsiwall External Wall Insulation System to be installed at Brize Norton which would provide a thermal conductivity reading of 0.032 Wm²/K. Whilst this aspect of the system would improve energy conservation, the 1.5mm HECK Textured Silicone finish transformed the appearance of the area. Previously dominated by dark, weathered concrete panels, the houses appeared stark and outdated. The application of the light-toned silicone render has replaced this with a clean and smooth finish which not only modernises the aesthetic but also enhances the overall streetscape.

Design & Installation Challenges:

As specialists in EWI and given our vast experience, installing the system across these houses was, overall, a fairly straightforward process compared to a lot of the complicated and problematic projects we’ve previously worked on. The layout and condition of the properties meant that access was unrestricted and the uniformity of the buildings allowed for a consistent approach across the estate.

There were of course a few minor challenges though. Firstly, working on a Ministry of Defence site meant that we were met with security and access restrictions in place due to the nature of the land and surroundings. This also meant we were working under regulatory constraints which required additional approvals and specifications, differing from local authority guidance for example. However, throughout the process, we maintained regular communication with the relevant liaison to ensure that all tools, scaffolding and waste management met their safety and security standards.

The other slight issue we came up against was the nesting birds and bat populations living in some of the homes, both of which are protected under the Wildlife and Countryside Act 1981 as well as the Conservation of Habitats and Species Regulations 2017. Where active nests or bat roosts were found, we temporarily postponed works on affected elevations until we had confirmation from the ecologist that the wildlife had safely vacated. These measures ensured legal and ecological obligations were fully met without significant impact on overall project delivery.

Measured Results:

The client’s expectations were met upon completion, with the Wetherby 90mm EPS system achieving the target U-Value of 0.032 Wm²/K.

We were also able to create a crisp and uniform exterior which elevated the appearance of the entire neighbourhood. The installation of the 1.5mm textured silicone finish brought about a striking visual transformation of the surroundings.

Project Completion

Despite our start date being delayed due to the bird nests and bat roosts, we still managed to complete the project within the projected time frame; 59 properties in 6 months. As such, and although the original finish date wasn’t met, we still walked away from this job with a satisfied client and an array of grateful residents who are now benefitting from more energy efficient living spaces.

Feedback:

Toby Britton, Technical Sales Manager at Wetherby Wall Systems:

“PJ Mear have delivered an outstanding installation on the low-rise MOD project at Brize Norton. Their workmanship, professionalism, and attention to detail have ensured that the EWI system was applied to the highest standard. The result is a high-quality, durable façade solution that reflects the excellent collaboration between all parties involved.”
