Sika-Trocal provided a watertight roofing solution for the National Memorial Arboretum.
Working with contractors Maincare Roofing and Building they completed a complex, multi-roof installation that was Highly Commended at the Single Ply Roofing Association (SPRA) Awards.
The National Memorial Arboretum is the UK’s year-round centre of Remembrance for those who served and continue to serve in the Armed Forces, it opened to the public in 2001 and contains more than 300 dedicated memorials.
In December 2015, Maincare Roofing and Building was selected to supply 14 roofing systems of differing size and complexity to the Arboretum’s new £15.7 million Remembrance Centre.
The roof systems not only had to provide the highest level of waterproof protection, each had to offer a crisp, uniform look in order to maintain the centre’s aesthetic properties.
Ideal for mechanically-fastened roofs in new build and refurbishment applications where quality and speed of installation is a priority, the Sika-Trocal Type S system was selected for the high-profile project.
Sika-Trocal Type S, does not require a separate fastening system for the thermal insulation as it utilises the same disc and fastener for securing the insulation and the waterproofing membrane, thus improving speed of install.
A total of 3,500m2, 2mm Type S was applied during the Remembrance Centre project.
Upstands, such as kitchen extractor fans were prominent throughout the installation, adding to its complexity. To ensure the symmetrical appearance of each installation, roofing laps had to be perfectly aligned and metal-affixed butt straps required ‘marrying’ with all corners.
Thanks to the flexibility of the Type S system, these additional features were accommodated with ease without compromise to its watertightness.
To provide stronger support in areas such as roof balconies and terracing where foot traffic was potentially high, a total of 300m2 Sika-Trocal SGmA was installed.
The multi-layer, synthetic roof waterproofing sheet is based on premium quality polyvinyl chloride (PVC) and contains an inlay of non-woven glass fibres. As well as offering quality, long-term SGmA is deemed to achieve an FAA fire rating.
Carl Pryce, Contractors Director at Maincare Roofing and Building, said: “For such a high-profile and potentially challenging project, we needed a roof system that excelled in terms of ease and speed of application, as well as long-term performance and aesthetic qualities. The specification of Sika Trocal Type S, coupled with the skill and dedication of our installation teams, was absolutely crucial to the roofing programme’s success.”
