Kingspan Kooltherm products specified for mixed-use development

A selection of products from the Kingspan Kooltherm range have been specified to improve thermal efficiency at the new Fitzroy Place development in London.

Erected on the former site of the old Middlesex Hospital, Fitzroy Place is a mixed-use estate comprising two office building, retail areas, a restaurant, and almost 300 residential spaces, including affordable homes and private apartments.

The estate was developed by Exemplar and Aviva Investors, designed by Sheppard Robson and Lifschutz Davidson Sandilands, and constructed by Sir Robert McAlpine.

Incorporating the original hospital’s chapel and sections of its Victorian façade, the estate has been designed with an emphasis on energy efficiency. To ensure the development obtained an ‘Excellent’ BREEAM rating, the team adopted a fabric-first approach to construction, specifying Kingspan Kooltherm products for use throughout the site.

Improving thermal efficiency with Kingspan Kooltherm

Kingspan Kooltherm K15 Rainscreen Board was used to insulate the rainscreen elements of the new buildings’ façade, which combines concrete, glass, and traditional red-brick. Kingspan Kooltherm K12 Framing Board was fitted between  the timber battens on the masonry sections of the buildings’ external walls. 

Manufactured at Kingspan’s dedicated Pembridge facility, both systems are certified to ‘Excellent’ under BES 600, and boast a BRE Green Guide rating of A+.

The use of these products enabled the project to achieve thermal conductivities as low as 0.020 W/m^.K, whilst contributing towards the award of credits within the BREEAM assessments for the office sections of the development. 

The existing façades, reminiscent of the former hospital, which are situated along Nassau Street and No. 10 Mortimer Street, have been sensitively restored. Kingspan Kooltherm K7 Pitched Roof Board was used as part of a new mansard roof, which has been constructed for the buildings located behind them. This addition enabled to project to obtain U-value 0.13 W/m^.²K with a minimal construction depth.
