Luxury living with Kingspan OPTIM-R Rainscreen System


The Kingspan OPTIM-R Rainscreen System has provided an ultra-slim solution for Taylor Wimpey Central London’s development in the historic London borough of Westminster.

73 Great Peter Street features twenty-two luxury apartments and a further two penthouse suites, offering stunning views out across central London. White Ink Architects’ intricate brickwork design takes inspiration from the surrounding architecture whilst remaining thoroughly modern. Winter gardens are used to add depth and definition to the design and the external facade of these recessed areas have been finished with bronze coloured metal cladding.

McAleer & Rushe have completed the building with a meticulous attention to detail, both inside and out. When it came to insulating the rainscreen at the rear of the winter gardens, they required a solution which would allow them to meet the energy performance requirements within the London Plan, without reducing internal living space. To achieve this, they specified the Kingspan Insulation OPTIM-R Rainscreen System.

Kingspan OPTIM-R vacuum insulation panels (VIPs) feature a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. This design allows them to achieve optimum levels of insulation performance with an aged design value thermal conductivity 0.007 W/m.K. The OPTIM-R VIPs are accompanied within the Kingspan OPTIM-R Rainscreen System with OPTIM-R flex infill panels, which can be cut to fit around penetrations.

For the cladded sections at the rear of the winter gardens, 40 mm thick Kingspan Insulation OPTIM-R Rainscreen System was used. Kingspan Insulation’s expert technical team provide detailed System layouts to help streamline the installation whilst keeping the construction thickness to a minimum.

The Kingspan Rainscreen System is manufactured under a management system certified to ISO 14001: 2004. Kingspan OPTIM-R Systems are certified by LABC Registered Details, when installed to Kingspan Insulation’s recommendations. In addition, 20 mm – 40 mm Kingspan OPTIM-R panels are also certified by BDA Agrément, offering a fast-track route through the checking and approvals process.
