The campus technology centre, designed by architects Sinclair Knight Merz, provides facilities for the teaching of the technology curriculum for the school's year 7 and 8 students. An Alsynite roofing system composed of translucent twin skin Alsynite cladding was specified for the project.
This unique twin skin roofing system, incorporating Topglass GC Ultra-Safe, provides light, shelter and some thermal insulation to the courtyard of the building. It is designed to glow from the outside when lit, providing a dramatic night time effect.
Topglass GC Ultra-Safe is manufactured using a heavy-duty woven roving enclosed within the resin matrix, which provides a structural capability not normally available with traditional translucent roofing materials. It meets the impact strength tests of AS/NZS 4040 and satisfies the requirements of AS 4256.3, eliminating the need for safety mesh to be installed under the sheeting. This is of particular benefit to building designers who may come across issues in education facilities where the design of the building can be compromised aesthetically. As the roving matrix runs both longitudinally and laterally within the sheet, Topglass GC Ultra-Safe demonstrates exceptional high impact strength.
To meet the requirements of the NZBC verification method C/VM2 appendix A and NCC specification C1.10, Topglass GC Ultra-Safe can be manufactured incorporating Alsynite's premium FR-50 or FR-60 fire retardant Bromine Free resins, tested to NZBC group 3 and 2 classification for surface lining materials.
A 130um* Exo-set 206 Premium Gel-Coat surface provides long term light transmission and is supported by a 20 year weather surface structured warranty.
