Chryston High School

Veitchi partnered with BAM to deliver an extension to Chryston High School. The project was shaped by factory-led innovations and smart sequencing that reduced time on site while improving safety, quality, and overall efficiency across the external envelope works, including infill SFS installation, parapets, and airtightness detailing.

Key delivery elements

• Infill SFS installation to form the primary wall framing and support the façade build-up
• Off-site manufacture and pre-assembly of 400+ linear metres of SFS parapets
• Factory pre-bonding of Wraptite membrane to sheathing boards

Innovation 1: Off-Site Manufacture of SFS Parapets

To streamline installation and minimise on-site work at height, parapets were sized precisely from detailed drawings and then manufactured and pre-assembled off-site. This work was carried out at our Glespin facility (south of Glasgow), where we could control quality and reduce the amount of cutting required on site.

Parapets were sized directly from the detailed design information, with components then fabricated and pre-assembled in a safe, controlled factory environment. This approach minimised cutting on site, improving both safety and consistency, and the completed units were delivered on a just-in-time basis, arriving ready for installation.

Benefits delivered:

• Reduced installation time on site
• Improved safety by minimising work at height
• Lower noise and disruption
• Zero material waste
• Higher productivity and quality

Innovation 2: Pre-Bonding of Membrane to Sheathing Boards

To improve both the speed and quality of membrane installation, Veitchi Interiors pre-bonded the Wraptite membrane directly to the sheathing boards in our factory. Completing this process in a controlled environment ensured a consistent finish and removed weather risk from a critical stage of the programme.

Benefits delivered:

• Significant time savings by reducing site installation time
• Superior, consistent bonding through factory-controlled application
• Weather risk eliminated (no exposure during installation)
• Safer working conditions through fewer on-site steps
• Better overall product with improved durability and precision

By combining programme-led infill SFS installation off-site parapet manufacture with factory pre-bonded membrane boards, the project delivered faster overall progress, created a safer working environment by reducing time and complexity on site, improved quality and consistency through controlled factory processes, and reduced waste and environmental impact by minimising on-site cutting and rework.
