'The Peak'- Queenstown Hill
Challenge
A magnificent property designed by renowned architects Mason and Wales was being constructed atop of the peak of Queenstown Hill.
The construction timetable dictated that the roofing system would have to be installed in winter, meaning temperatures consistently below 0 degrees Celsius and snow and ice most days. A fully adhered membrane system was initially specified for this low slope roof. However, the anticipation of compromised adhesion due to the application of adhesives in cold temperatures meant that this was not practical for the time of year.
Solution
Viking Roofspec, being a ‘solutions provider’, recommended one of their fit for purpose two-layer torch-on systems better suited for the environmental conditions. Viking GM Lybra S.B.S is a torch-applied membrane meaning no adhesive is required, therefore dictating that Viking Bituclad SBS (now named Viking GM Lybra SBS) could be installed in cold temperatures.
Bituclad, being of the S.B.S variety (styrene butadiene styrene) is specially-formulated to manage large temperature fluctuations between winter and summer without fracturing. Central Otago temperatures range from below 0 degrees Celsius in winter to 30+ degrees Celsius in summer, meaning Bituclad S.B.S was a well-matched solution for this Queenstown property
Result:
This was an illustration of Viking and the applicator using their technical expertise to match an appropriate membrane solution to the project’s requirements. Additionally, Viking was so confident in the specification and the experience of the applicator, that a Viking Full System Warranty was issued for this project. This meant that the product and installation warranties were both covered in one warranty document for a 20-year period. The applicator was very pleased with the final result,commenting; “Viking Bituclad allowed us to complete the project in the harshest of temperatures and conditions and still get a perfect finish on time.”
NOTE - Viking Bituclad SBS has now been replaced with Viking GM Lybra SBS, this membrane is part of a new range of torch-on waterproofing systems offered by Viking.
