Windermere Jetty - Museum of Boats, Steam and Stories

This multi award-winning museum has taken form with a copper clad envelope featuring high quality rainscreen insulation and pitched roof insulation.

The Project

The Windermere Jetty – Museum of Boats, Steam and Stories offers a unique visitor experience, combining a diverse collection of historic boats, live conservation workshops and high-quality architecture. The building has been constructed by Thomas Armstrong and was named Design of the Year and Cultural Project of the Year at the 2019 AJ Architecture Awards. In developing the design, the architects were keen to do justice to the rich social history contained within the museum and its stunning lakeside location. Following an extensive study of cladding materials and how they would respond to the challenging Lake District climate, they selected a corrugated oxidised copper cladding for the rainscreen façade and roof. 

The sustainability of the museum was a priority throughout with the buildings carefully oriented to ensure high levels of natural light. The buildings were also designed to be highly energy efficient and as part of this approach Kingspan Kooltherm K15 was specified for the walls of the main museum building with Kingspan Thermapitch TP10 chosen for its pitched roof.

Kingspan Kooltherm K15 is the first insulation board for rainscreen cladding applications to achieve LABC Registered Detail status. With a thermal conductivity as low as 0.020 W/mK, the boards allowed the design team to achieve excellent fabric performance for the walls of the museum. Its lightweight design also streamlined the installation process in the challenging lakeside setting. The outer copper cladding will gently patina over time, adding green hues to the dark brown cladding. 

The museum’s pitched roof has been created to echo the form of many of the local boat houses. Kingspan Thermapitch TP10 was a natural choice for this element. Its fibre-free insulation core has a thermal conductivity of 0.022 W/mK and has been specifically developed for use within a variety of pitched warm roof constructions. 

In addition to their excellent thermal performance, the Kingspan Insulation boards also contributed to the wider sustainable goals of the project. Both products have been assigned the highest possible summary rating of A+ under the BRE Green Guide and the boards produced at Kingspan Insulation’s Pembridge site are certified ‘Excellent’ under the demanding BES 6001 responsible sourcing standard.
