Sika Sarnafil S327-15EL single ply membrane in Copper Patina was used for an art deco roof refurbishment at Castlebrae Business Park.
A 1936 listed building with stunning art deco details, designed by architects Reid and Forbes, Castlebrae Business Centre was a former school that needed desperate renovation to benefit the local community.
As part of an extensive £2m renovation project to provide over 35,000ft2 of modern commercial space within the building, roofing contractor, Avonside Scotland, and Sika Sarnafil stepped up to challenge of refurbishing the roof, with no disturbance to the offices below.
The new roofing system had to be sympathetic to the heritage and style of the construction. At 2,200m2, the roof of Castlebrae was incredibly complex, split into 16 separate areas, each with its own set of considerations.
The listed status also meant that the outside edge detail at roof level had to remain unchanged. Furthermore, the top of the parapets contained original glazed bricks that had to remain visible and untouched.
To emulate the original green mineral felt system on the roof, a Sika Sarnafil S327-15EL single ply membrane in Copper Patina was selected for the project.
Avonside and Sarnafil worked together to draw up a bespoke Sarnametal detail, ensuring that the outside edge and glazed bricks were conserved.
The project was supervised and installed by Avonside’s team of Sarnafil trained fitters. Work was overseen by Sarnafil at every stage, with regular site visits to ensure that workmanship passed the high standard required to sign off the final guarantee of 15 years.
As several parts of the building were in use during the work, it was essential that disruption was kept to a minimum at all times. All deliveries and movement of materials were managed and planned into certain time slots, and constant diagnostics of the roof were completed to make sure it was totally watertight.
The end result is stunning, with the Sika Sarnafil Patina Green membrane complementing Castlebrae’s art deco aesthetic beautifully. The building has been restored to its former glory, and will be able to be used by the local community for many years to come.
