As part of Angus Council’s ongoing strategy to improve the energy efficiency and appearance of its housing stock, a major low-rise refurbishment scheme was undertaken in Montrose, Scotland. The project encompassed over 6,000m² of external wall area across multiple residential blocks, with the objective of delivering significant thermal performance improvements while enhancing the long-term durability and aesthetic appeal of the buildings.

One of the key challenges of the scheme was the diversity of property types. The site included multiple archetypes with varying construction methods, ages, and detailing requirements. This architectural complexity demanded a flexible yet robust external wall insulation approach to ensure continuity of performance and design across the entire development.

To meet this challenge, a hybrid PAS 2035 detailing methodology was adopted – an innovative move that ensured compliance with the latest retrofit standards while enabling tailored solutions for the different building forms. This approach allowed the project team to address specific detailing needs at junctions, eaves, openings, and interfaces with existing structures, reducing thermal bridging and minimising the risk of future maintenance issues.

WS2 Grey EPS with Dash finish was selected for its thermal performance, fire safety credentials, and compatibility with a range of substrates. Working closely with the system supplier and Angus Council, the project team developed bespoke detailing packages to suit each archetype, ensuring a seamless installation and a consistent external finish.

Despite the technical complexity, the project was delivered efficiently and to a high standard. The result is a cohesive and modernised estate that not only improves energy efficiency for residents but also contributes to the local authority’s wider goals around sustainability, fuel poverty reduction, and housing quality.

The Montrose refurbishment stands as a testament to the importance of technical adaptability and collaboration in large-scale retrofit projects. By combining expert system knowledge with PAS 2035-compliant design thinking, the project sets a strong precedent for future local authority-led EWI schemes.
