CARLISLE Construction Materials has expressed its delight after project partner Site Group won the Green Roofing category at the 2025 NFRC Scottish Roofing Awards.
The firm was honoured for the Tynecastle Student Accommodation project in Edinburgh, which features CARLISLE’s RESITRIX waterproofing system. The redevelopment of the former B-listed school combines the retention of its historic façade with two new student accommodation blocks, providing homes for more than 400 students.
The project, developed by S1 Developments, transforms the historic site. The roofing design is said to deliver ‘exceptional’ environmental performance through the integration of RESITRIX SK W waterproofing membranes, ALUTRIX vapour barrier membrane, blue and green roof systems, and solar PV technology. Across five roof areas, the design incorporates approximately 3,000m³ of rainwater attenuation to manage stormwater sustainably, reduce pressure on drainage networks, and support biodiversity.
Green roof planting aims to enhance the local ecosystem, while the inclusion of solar PV contributes renewable energy.
CARLISLE revealed that it provided technical support throughout the project, including specification advice, on-site inspections, and quality assurance. Site Group carried out the roofing installation, including blue and green roof systems, offering specialist design and training support.
Simon Glenn, project sales manager at CARLISLE Construction Materials, said, “This award is a fantastic recognition of true collaboration and technical excellence. Working alongside Site Group, we delivered a complex roofing system that balances sustainability, innovation and long-term performance. Tynecastle demonstrates what is possible when expertise is shared and environmental goals are prioritised.”
