Yorks new rail operating and training centre needed an insulation solution that could meet their environmental requirements, as well as meet the rigorous demands of an inverted roof application. The outcome was a specification of 3,000m2 of Polyfoam ECO Roofboard Extra (XPS) insulation that has a BRE Certified Green Guide Rating of A.
Network Rails York Engineers Triangle is the largest rail operating centre in the country and will control signalling and rail operations on the east coast, from London Kings Cross to the Scottish borders, housing the latest technology to manage and control the rail network. The development centre also provides a leading training facility with learning spaces that can allow for up to 200 delegates to be trained at any one time.
Liam Murray, Estimating Manager for European Roofing Systems commented: This expansive project had many different specifications and sustainability was at the heart of the development. The roof areas created a challenge that was met by our experienced design and site teams. With the help from Knauf Insulation we were able to develop an inverted roof system to meet the rigorous brief of requiring a product that had impressive environmental credentials, an excellent thermal performance and most importantly could be installed above a hot melt waterproofing system.
Knauf Insulations Polyfoam ECO Roofboard Extra insulation has excellent structural strength and is less prone to site damage than other rigid foam insulation boards. The thermal performance is also unaffected by site conditions such as wide fluctuations in outside temperatures and repeated freeze thaw cycles, which is ideal for a project like the York Engineers Triangle - so we decided to install this product.
Liam continued: The Polyfoam ECO Roofboard Extra insulation is available in a wide variety of thicknesses from 70mm to 220mm - developed to meet key U-values from 0.25 to 0.15 W/m2K in a single board. With help from Knauf Insulations technical team, they were able to produce the exact size we needed excellent service!
Luan Anderson, Network Rails project manager commented: When we first started this project we knew we wanted it to be as sustainable as possible. With brown roof spaces and green walls to help promote biodiversity on the site, combined with the installation of Knauf Insulations Polyfoam ECO Roofboard Extra and cooling and heating systems, we believe that the sustainability will permeate further than the actual building and help us to save energy consumption and reduce our CO2 emissions.
