NEW ROOF FIRMLY FASTENED ON £22 MILLION

We have completed our first project using the new ISO-TAK® TIA fastening system at Gloucestershire Royal Hospital’s £22 million Women’s Centre
Our new thermal break, self-adjusting fastener system was specified by roofing contractors Single Ply Services Ltd to secure the 2,000 m2 flat roof on the hospital.
The roof area consisted of a concrete deck followed by a 1 in 60 tapered insulation scheme, above which was installed a mechanically fastened single ply membrane.
During the construction, I visited the hospital on many occasions to chat with Single Ply Service’s on-site team. Their reaction was very positive, and it was great to see how our tools and fasteners do their job to help contractors. The team were impressed with SFS intec’s ZAK drill extensions and ZVK-STOP drill bits because it meant that drilling could be undertaken standing up and without having to measure the depth required. What's more it also cored out the insulation making insertion of the fastener sleeves almost effortless!!
Using the ISO-TAK® TIA system, fewer fastener combinations were required due to the self adjusting capability of the product. The same fastener and sleeve combination can be used for changes of insulation
thickness of up to 100mm. This certainly made order procurement and site management much easier and helped to significantly reduce the installation time at the Gloucestershire project.
The team were certainly surprised by how few drill bits were used - half the number that would conventionally be required in fact. This unexpected cost saving is not really surprising considering the reduced drilling required with TIA. Working at a reduced depth also meant that the drill bits stayed well clear of the reinforcement bars, thereby extending the life of the drill bits further.
In true British style the team from Single Ply Service’s had to battle with mixed weather conditions during construction, including both rain and frost. In addition, the exposed site, demanded high design load requirements from the fixing system. It was great to see how using the ISO-TAK® TIA fastening system, the installers were able to mechanically fix into the concrete deck, even when temperatures were below 5°C.
See how simple and quick the installation of the tapered flat roof, including Sika Trocal membrane, was by watching our new video.
