Worcestershire based ESP supply hygiene products to industrial customers, so a fast-track transition into a new custom designed building was key to this project. The design proposal incorporated an expansive flowing roof that would harmonise with the ten mile spine of rolling hilltops famously known as ‘the Malverns’; and the landscape that inspired Elgar’s ‘Land of Hope and Glory’!
With build time at a premium, the specification team opted for Kingspan’s membrane faced Topdek insulated panel, normally specified as a fast and reliable new-build solution for flat roofing. In this instance 100mm panels faced with Sika Trocal membrane were chosen. Given the sheer size of the new ESP building, the dynamics meant that not only was the roof required to seamlessly curve but practically, it needed to cover an area of 15,500 square metres – a virtually unheard innovation for the Topdek system.
Whilst Kingspan conducted testing scenarios to ascertain radius performance, the main contractor turned to Leicestershire based Spectrum Building Envelopes & Facades to install the roof.Contracts Manager for SBEF Adrian Bidwell explained: “Spectrum has built a strong reputation with established contractors who rely on the quality of our installations, and the 'can do' attitude of our management team. We know the Topdek panels very well which in turn means we know EJOT’s Opticore system equally well”.
Right first time installation
Opticore is EJOT's unique integral nylon fastener head manufactured with precision cutting fins that core through membrane faced insulated panels, whilst the fastener self-drills the substrate in one simple operation. Installation is via a bi-hex and torx dual driving system. The Opticore range includes stitchers and provides a reliable solution for hot and cold rolled steel as well as timber substrates. Spectrum specified predominantly EJOT Opticore LS 5.5 x 25 and SF 6.3 x 25. Adrian continued: “With such a critical specification over a relatively short window, obviously the chosen fixings play a major part in getting such an innovative project right first time.”
