The complex, heavily engineered design for Glasgow’s Riverside Museum of Transport is the first major UK project for Zaha Hadid Architects.
The museum provides a new home for Glasgow’s transport collection. The development has a riverside location on a site where the River Clyde meets Glasgow’s other main river, the Kelvin, and is adjacent to Glasgow Harbour. The museum displays Glasgow’s rich industrial heritage, which stems from the River Clyde, with the Tall Ship berthed alongside.
The brief for design and build roofing specialist Varla (UK) Ltd was to find a flexible insulation that could meet the demanding U value of 0.20 W/m2K. This was required continuously over both the walls and the complex 18,000m2 roof.
Rigid foam boards were ruled out early on, as they could not be fitted to the building’s complex curves. There was also a limited cladding zone that could not be altered.
Varla started the search for a suitable material by contacting many insulation suppliers and holding supplier seminars at Varla’s Chester offices, challenging them to propose a solution to meet the demanding specification.
Varla chose to use Knauf Insulation’s FactoryClad 32, a flexible product that could provide a U-value of 0.20 W/m2K across both the roof and walls.
Knauf Insulation provided technical support to produce a solution that met all of Varla’s insulation requirements, by using a double layer of 100mm FactoryClad 32. This is a flexible, lightweight roll of resilient glass mineral wool with very high tear strength and a thermal conductivity of 0.032 W/mK.
Once Varla (UK) Limited had decided on Knauf Insulation, it leaned on them heavily for technical support, utilising the unique 3D heat loss calculation support service, which ensured the correct product thickness was specified to meet the demanding project requirements.
Many types of insulation were considered, but glass mineral wool roll provided the best thermal efficiency.
The key to Knauf Insulation’s products being specified on this project was its ability to provide in-depth technical support, including complex three-dimensional heat flow modelling calculations.
For public buildings such as this, superior fire performance is very important and FactoryClad meets this requirement. It limits the spread of fire, since it holds a Euroclass classification A1 for non-combustibility and will not burn. It also does not give off toxic smoke or suddenly ignite in a fire due to ‘flashover’.
