Bauder Successfully Delivers Ambitious Flat Roof Project for SEND School
16 Feb 2026
Sustainability and net zero objectives are increasingly important in the design of education buildings. Bauder’s role in the 2026 SPRA Sustainability Award-winning Perth High School Passivhaus project is testament to how public-sector experience, flat roofing technical expertise, and full-service provision can help deliver high-performing, sustainable, and future-ready learning environments.
Schools today are expected to do more than provide spaces for learning. More than ever, they must also operate efficiently, minimise environmental impact, and remain resilient throughout their lifecycle. As sustainability moves higher up the agenda for education estates managers, designers, and contractors, a fabric-first approach is becoming essential to creating buildings that reduce energy demand, improve occupant comfort, and support long-term operational performance.
Perth High School in Scotland is an excellent example of this shift in practice. The £80 million development, one of Scotland’s largest Passivhaus schools (almost 6,000 m2), was built to replace a 50-year-old facility that no longer met the needs of modern education.
Accommodating up to 1,600 pupils and 140 staff, the school demonstrates how sustainable design, specialist expertise, and collaborative delivery can create a high-quality learning environment fit for the future. Its success was recognised nationally when it won the Sustainability Award at the SPRA Awards earlier this year.
Alongside rooftop photovoltaic (PV) panels and other low-energy design measures, the building envelope was identified as a critical factor in achieving the school’s ambitious sustainability objectives.
Creating energy-efficient schools require a high-performing building envelope to reduce heat loss, improve comfort, and support the building’s overall sustainability goals.
In the building of Perth High School, Bauder played a central role in helping achieve these aims through the design and installation of its flat roof system. Installed across almost 6,000 m² of roof space, the specification combined Bauder’s Thermofol PVC single-ply roofing system with 320 mm of BauderROCK mineral wool insulation.
The insulation helps maintain a continuous thermal envelope across the building, reducing heat loss and supporting energy efficiency, while the Thermofol membrane delivers durable weather protection and contributes to the airtightness required for Passivhaus performance. Together, these elements helped create a roofing solution capable of supporting the school’s ambitious environmental objectives while providing long-term durability.
The scale and complexity of the project, which included atrium spaces, sports halls, and plant areas, required close collaboration between all parties. Working alongside the wider project team, Bauder helped ensure the roofing solution integrated seamlessly with the building’s overall performance strategy.
The result is a school that not only meets demanding sustainability requirements but also provides a comfortable, healthy and efficient environment for students and staff.
Projects such as Perth High School highlight the growing importance of considering sustainability from the earliest stages of design. Achieving meaningful reductions in energy consumption requires careful planning and a holistic approach to the building envelope, rather than relying on individual technologies or products in isolation.
For education estates, this approach can deliver multiple benefits, including reduced operational costs, greater resilience, improved occupant wellbeing and a lower environmental impact over the building’s lifespan.
As sustainability ambitions become more demanding, selecting the right partners is increasingly important.
With more than 160 years of flat roofing experience, Bauder works closely with architects, contractors, consultants, and responsible bodies in the education sector throughout a project’s lifecycle. Its support extends from early-stage design advice and specification development through to installation guidance and long-term asset management.
Rather than focusing solely on roofing products and solutions, Bauder takes a broader view of how roof systems contribute to the performance of the entire building. This collaborative approach helps project teams make informed decisions that support sustainability targets, manage risk, and maximise long-term value.
Perth High School highlights how early collaboration and specialist expertise can deliver a roofing solution that supports Passivhaus standards while supporting the long-term performance of a modern educational facility. It stands as a strong example of sustainable design in action, creating an efficient, future-focused building.
