The Kingspan OPTIM-R flooring system has been installed as part of the £1bn refurbishment of London Bridge Station. The system was specified in two retail units due to its optimal thermal performance. This allowed the floor construction depth to be minimised, providing an even transition for shoppers entering from the concourse.
Some of the retail units constructed on the lower concourse were situated directly above uninsulated platform space. As such, specifiers required an insulation solution which could provide the required thermal performance in a slim thickness — avoiding the need for a step-up from the outer concourse. With an insulation performance up to five times that of commonly used insulation materials, Kingspan OPTIM-R vacuum insulation panels (VIPs) provided a clear solution.
The Kingspan OPTIM-R Flooring System was specified in a 25 mm thickness which was fitted above a 3 mm rubber crumb layer. Despite the slim build-up, the outstanding thermal performance of the OPTIM-R Panels ensured the units met their U-value target.
Kingspan OPTIM-R panels have a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. With this design, the panels achieve a declared thermal conductivity of 0.007 W/m.K. The VIPs were installed as part of the Kingspan OPTIM-R Flooring System. OPTIM-R flex infill strips of the same thickness are also supplied with each system to fill awkward gaps and to allow penetrations in the insulation layer.
20mm – 40 mm thick Kingspan OPTIM-R panels are certified under BDA Agrément scheme.
