Keswick Convention Centre, Keswick Ministries organization

An historic landmark in the Lake District has been given a new lease of life with the installation of StoTherm Mineral K external wall insulation and StoSilco finishing render. Built in 1937, the building in Keswick originally housed the UK’s first pencil factory, and now provides new headquarters and site for the Keswick Convention for the Keswick Ministries organization.

After being used by the Cumberland Pencil Company the building had fallen into disrepair. Set at the entrance to Keswick, this important local landmark has now embarked on a £10.5m redevelopment project, split into four phases. The Sto materials have been used on the first phase which has seen the building’s front elevation fully restored, and they have also been specified for the remaining three stages of the work.

The BBA-certified StoTherm Mineral K system combines impressive insulation with unrivalled fire protection characteristics. It features Sto-Mineral Fibre thermal insulation boards, which in this case were fixed to the substrate using StoLevell Duo Plus mineral bonding and reinforcing mortar.

“This allows any unevenness in the surface of the substrate to be accommodated and makes installation a fast and easy process,” comments Alan Rees of Eco Rend North East who installed the Sto system. This efficient single-leaf construction allows for excellent thermal performance without reducing the interior space, and as it requires no additional expansion joints, a smooth and unbroken exterior surface can be created.

An additional mineralic reinforcing coat was applied and the exterior surface was finished with StoSilco silicone resin render.  With high CO² and water-vapour permeability, StoSilco render allows a weather- and water-repellant outer surface to be created in any of the 1,000+ colours available in the StoColor System.
