Castleford College – New Build Roofing Installation

High-Performance Sika Single Ply Roofing for a Modern Educational Facility

CASE STUDY

Project: Castleford College
Location: Castleford, West Yorkshire
Roof Area: 1,245 m²
System Manufacturer: Sika
Guarantee: 20 Years

Castleford College Roofing Project Overview

As part of the development of a new, state-of-the-art educational facility, Castleford College required a high-performance roofing system that would provide long-term durability, energy efficiency, and low maintenance. The roofing package was a key element of the new build design, ensuring the building performs effectively for both staff and students while supporting modern teaching and learning environments.

Scope of Works for the Castleford College Roofing Project

The roof was constructed over a D200 metal decking substrate with trapezoidal acoustic roof infills, providing excellent structural integrity and acoustic control suited to a busy educational setting.

The build-up comprised:

  • Vapour Control Layer: Sarnavap 1000E
  • Thermal Insulation: Sikatherm PIR GT 150mm, mechanically fastened for consistent fixing and enhanced thermal performance
  • Waterproofing Membrane: Sikaplan SGK-18, fully adhered using Sikaroof Adhesive 500

Additional features included:

  • ManSafe posts installed and fully waterproofed for future roof maintenance safety
  • Sika walkway tiles welded down to form a clear, designated access route
  • Bilco roof access hatches to facilitate safe and easy roof access
  • Velux rooflights to maximise natural light within internal spaces
  • Solar PV panels installed to contribute to the college’s renewable energy and sustainability targets

The completed roofing system was fully warranted with a 20-year Sika guarantee, ensuring long-term reliability and client confidence.

Project Delivery

This was a complex new build project, requiring careful coordination with other key trades — particularly the cladding and SFS (Steel Framing System) installers. Effective communication and sequencing on site were critical to maintaining progress and avoiding interface issues at upstands, perimeters, and penetrations.

Working collaboratively with the main contractor and design team, the roofing works were completed safely, efficiently, and to a high standard of finish, fully compliant with Sika’s installation guidelines and British Standards.

Castleford College Roofing Project Outcome and Benefits

The new roofing system at Castleford College delivers a robust, thermally efficient, and watertight envelope for this modern educational facility. The integration of high-quality Sika components ensures long-term performance, minimal maintenance requirements, and enhanced safety for future access and inspection.

For students, the result is a comfortable, quiet, and energy-efficient learning environment, benefiting from improved insulation and acoustic control.
For teachers and staff, the building provides a safe, bright, and sustainable workspace, with reduced maintenance costs and improved operational efficiency.

Conclusion

The Castleford College new build roofing project highlights the importance of technical precision, teamwork, and high-quality materials in delivering reliable, high-performance roofing solutions. The completed system provides a durable, efficient, and future-proof roof — helping to create an inspiring educational environment for generations to come.

The Castleford College project is a great example of how modern roofing systems can combine performance, sustainability, and long-term value. By choosing a Sika single ply membrane, the college has invested in a system that not only delivers exceptional waterproofing and energy efficiency but also supports the environmental goals of the wider campus. The integration of solar PV panels further enhances the building’s sustainability credentials, helping reduce operational costs and carbon footprint over time.
