Bailey have supplied a full curved roof and eaves system for a £2million development at St Andrews on the Links. The development has been designed as a state of the art facility providing storage and office facilities.
The building designed by local architect Archial, features a green barrel roof to help the building settle into the natural environment around it. The roof covering was an important aspect to, not only meet planning considerations but also achieve the sustainability credentials required on the project. A special mix of sedum was specified to retain the local blend of vegetation and to tolerate the exposed location of the St Andrews Gold Club at the edge of the North Sea.
Whilst the green roof is integral to the visual impact of the building, there were some questions as to how the roof could be installed. At its steepest, the roof pitch was nearly vertical. To ensure successful installation of the green roof, Bailey undertook a constructability study at their West Sussex head office.
The full curved roof and eaves system was provided by Bailey and included cassette fascia soffit system, VCL, insulation, fixings, waterproofing from Bailey Atlantic and finally Bailey Eco-roof green roof system.
Using the scale mock-up it was clear that the sedum would need to be secured at 460mm intervals using green roof trims. A nylon ‘string’ was then ‘zig zagged’ across the sedum in between the trims, further securing the vegetation mat. This nylon system will enable the sedum to root itself ultimately becoming self-securing.
Bailey Cassette Fascia soffit system supplied to this project included a secret fix curved fascia which wrapped around the perimeter of the roof and a v-plank soffit system. The composition of this system ensured each panel remained truly flat, without any ripples and fixing dimples thus ensuring a smooth curve to the roof detail.
Installation was a complex combination to deliver a complete system. The Eco-roof reservoir board has a protection fleece either side and was loose laid onto the Bailey Atlantic waterproofing. The growing medium and sedum was then installed and ‘tucked’ into the green roof trims while the nylon secured the system. Although difficult, the internal testing meant Bailey Total Building Envelope had to work with both specifier and contractor to deliver the whole solution.
