INCA Case Study: YMCA Motherwell

Project Overview

The YMCA Motherwell redevelopment is a shining example of how External Wall Insulation (EWI) can be used to sensitively upgrade historic buildings for modern living without compromising architectural heritage.

Originally constructed in 1898, the YMCA building in Motherwell is a B-listed Scottish landmark with deep civic and historical significance.

After falling into disrepair and becoming derelict in 2014, the building was brought back to life through a wider regeneration project led by CCG (Scotland) Ltd.

This transformative development involved the conversion of the YMCA into six high-quality apartments, alongside the construction of 42 new-build apartments on an adjacent site.

At the heart of this restoration was the careful integration of modern energy efficiency measures, achieved through the expert specification and installation of K Systems’ M External Wall Insulation system.

Project Challenges

Restoring a B-listed structure brings with it a range of complex challenges, particularly where conservation, compliance, and sustainability must all align.

The defining difficulty in this project was the need to preserve the original sandstone façade on the front and side elevations, key features that are protected under the building’s listed status.

These historic elements could not be altered, meaning traditional insulation methods were not viable. However, the rear elevation, less architecturally sensitive and out of public view, presented an opportunity.

The goal was to improve thermal performance while preserving the historic character. The execution, however, demanded precision, innovation, and respect for the building’s heritage.

Additionally, working with a long-derelict structure introduced further challenges, such as stabilising weakened masonry, addressing outdated internal layouts, and coordinating works within a tight and active construction site shared with a simultaneous new-build programme.

System Specification

To meet the project’s demanding specifications, the K Systems M EWI system was selected, utilising 100mm Mineral Wool insulation and an Ash White Silicone Thincoat render finish. This system was ideal for several reasons:

• Thermal Performance: The 100mm Mineral Wool delivered excellent U-values, drastically improving the energy efficiency of the previously uninsulated rear wall.
• Fire Safety: As a non-combustible solution, the system provided vital fire safety for the new homes created within the historic structure.
• Breathability & Compatibility: The system’s breathability was critical for use on a traditional masonry substrate, ensuring moisture could escape and reducing the risk of long-term damage.
• Aesthetic Sensitivity: The Ash White Silicone Thincoat render finish was chosen to visually complement the existing sandstone, offering a modern performance layer that felt naturally in tune with the heritage palette.

Installation & Execution

Installation was carried out by PWM, K Systems’ approved applicator, with close technical support and quality assurance from the K Systems team. Weekly site visits, on-site guidance, and collaborative planning ensured detailing was consistent and sympathetic to the building’s form.

Given the adjacent live construction site on which 42 new flats were being built, logistics were a key consideration. Material deliveries, access routes, and safety protocols were meticulously managed to avoid clashes between projects, keeping progress on track and disruption to a minimum.

K Systems’ proactive involvement ensured that every aspect of the installation aligned with both heritage requirements and performance objectives.

Outcome & Impact

The finished project is a testament to the power of collaboration, craft, and carefully selected materials.

The once-derelict YMCA now stands revitalised, its original stone frontage proudly preserved, its interiors transformed into warm, efficient homes, and its rear elevation discreetly modernised with EWI.

This blend of old and new has resulted in a building that not only meets modern building standards but also honours its architectural past.

Testimonial

“As always, K Systems’ site support was great, with weekly visits carried out. Technical information was given timelessly, deliveries were delivered on time, and the team worked well together to deliver a great looking elevation. The client (North Lanarkshire Council) was delighted with the end result of what was a derelict YMCA building.”
