Case Study:

The LNER Stadium - York


The LNER Stadium is home to York Football Club and York Knights Rugby League team.

The 8,500 capacity stadium was developed by main contractor, Buckingham Group in what was a £40 Million project and completed in 2020. The extensive stadium is now home to leisure and corporate meeting facilities as well as an NHS outpatient centre, library and a plethora of retail outlets in what is a massive boost to the local community. With the four year project now complete, the stadium should help bring elite sport to the York community and allow the football and rugby league teams to progress up the league tables and into the big time!

The Project


The Buckingham Group called us to enquire about alternatives to using Rockwool Insulation for thermal line of the East Stand. Left exposed to the public, the underside of the stand stepped down and represented a zone where the cold external air could combine with the warmer interior to create condensation and heat loss points. As a habitable space, the fire performance of any insulation solution was vital and the finished, exposed appearance needed to look presentable for the passing public. Not ones for passing up an opportunity to find new solutions for spray foam insulation, ThermoFoam happily obliged with an acceptable specification!


Spray Foam Insulation is applied as a liquid and rapidly expands to its finished state, therefore, it’s very hard to achieve a flat and smooth finished appearance. As this project would have areas visible to the general public, we opted for a high density, class 1 fire-rated Nexseal Closed Cell Foam. To achieve a Class 0 surface spread of flame, we then coated the closed cell foam with a fibrous cement-based, spray-applied coating with an average thickness of 25mm. We utilised some of the very best spray foam installers in the UK for this project so that we could achieve a good finished appearance and the overall system complied with the required u-value target of 0.18 w/m2k.
