Housing Scheme, Salford


Alumasc’s Swistherm External Wall Insulation (EWI) system has been used to transform the thermal performance and aesthetic appeal of a social housing scheme in Salford. Managed by multi-award-winning social housing company, Salix Homes, the 54 flats at Stoney Knoll and Gloverfield are No Fines Construction which is typically regarded as ‘hard to treat’.

The Swistherm EWI system was a key element in the programme of works to upgrade the flats to Decent Homes standards. BLD Construction installed 3,000m2 of Swistherm with 110mm EPS insulation to all the external walls, finished with ST Silkolitt silicone render in off-white with a rolled texture.

The installation has dramatically improved the thermal performance of the properties, with U-values improving from 2.0w/m2k to an impressive 0.30w/m2k.

Externally, the ST Silkolitt silicone render has helped to transform the buildings’ appearance, achieving a clean, contemporary finish to meet the client’s brief. The refurbishment of the scheme has helped to improve the residents’ living conditions whilst also contributing to the regeneration of the area.

Having worked extensively with Alumasc previously, BLD Construction had no hesitation in recommending Swistherm for this project. Director Bruce Day commented: “The No Fines surface of these properties was very uneven. Swistherm enabled us to get a true and even line so the facade was as smooth as possible – the refurbishment has given a real boost to residents. Alumasc’s systems are our preferred EWI solution, as the material is superior and we find Alumasc’s sales, service and technical support at every level, to be second to none.”

Swistherm is a BBA approved, fully warranted, thin coat insulated render system comprising insulation slabs which are mechanically fixed direct to a continuous substrate. The choice of insulation materials includes Mineral Wool, Expanded Polystyrene and Cork.

Swistherm can be faced with Alumasc’s range of Silicone or Mineral renders which create a rolled surface texture, in a wide range of colours.
