Alumasc’s External Wall Insulation (EWI) systems have been specified on the historic Textile Building on Chatham Place in Hackney, resulting in a weather-proof, energy efficient and attractive building exterior being achieved.
This urban warehouse redevelopment, offers both residential and commercial space on the site of the former Burberry fashion factory. The refurbishment of the original Victorian building includes a new build section to the top, providing luxury penthouse living space.
Specified by architects Buckley Gray Yeoman and installed by CNJ Plastering, Alumasc’s Swistherm EWI system was installed around all existing elevations of the Textile Building, including the stairwells and courtyard garden areas. The original late 19th century building was of solid brick construction and in very poor condition.
Swistherm was selected for these areas as it could be directly fixed to what was a poor quality substrate. CNJ Plastering and the Alumasc Technical Team worked closely together to ensure the EPS insulation within the system was fixed in a variety of thicknesses to level the variations in the surface and provide the solid and even base required for the application of the final render finish.
A further challenge of the scheme related to the high tech new build sections that were being constructed. The aim was to replicate and blend in the rib-type detail on the existing building with the new build element, creating a seamless transition between both parts.
Alumasc’s Swisrail EWI system met the design brief on the new build upper levels of the building, as it is ideal for use on framed buildings, complying with NHBC guidelines. Swisrail comprises a series of steel rails and channels, which were used to create a 25mm drained cavity between the insulation and the framed building.
The final contemporary finish on both the refurbished and new sections of the building was achieved with Alumasc’s silicone and mineral renders, coloured white and shades of grey to meet the architect’s specification.
John Douglas, director at CNJ Plastering, comments:
“The building was in a really sorry state to begin with but, by working with the Alumasc team, we were able to overcome its many problems and create a strong and flat working surface on which to apply the EWI system.
We’ve worked with Alumasc for many years on various projects, and it’s this positive history which made us confident that the Alumasc EWI system specified would cope with the challenges of the scheme. We are delighted to have been involved and are extremely proud of the final result, as are the architect and the client.”
