Alumasc’s Swistherm External Wall Insulation (EWI) system and ST Silkolitt silicone render have been used for one of Glasgow’s largest ever residential regeneration projects – the refurbishment of 196 homes across five blocks of flats at St Vincent Terrace, Glasgow.
Swistherm was specified for its ability to meet the considerable challenges presented by the properties which are constructed from ‘hard to treat’ Bison Concrete Panels. The Swistherm system has achieved a significant improvement in thermal performance of the project with U-Values across the site being reduced to 0.28W/m2K.
The project was the largest external fabric upgrade ever undertaken by Alumasc approved installers, CCG (Scotland) Ltd, who installed a total of 20,000m2 of Swistherm with 100mm and 60mm mineral wool insulation to the facades and stairwells of five tower blocks ranging from 9 to 13 storeys high.
The sheer scale of the site and its location in the heart of a busy urban area presented major challenges with regard to health and safety, access and logistics.
At the time of refurbishment, St Vincent Terrace was managed by Glasgow Housing Association, who were keen to find an insulated render system that provided an appropriate contemporary finish for such a prominent landmark, whilst also meeting local planning regulations. Tenants were closely involved in the selection of Alumasc’s ST Silkolitt silicone render, which was specified in cream and a variety of blue shades.
Swistherm is a thin-coat insulated render system available for use with a choice of insulation materials including Mineral Wool, EPS and Cork. The system is BBA accredited, fully warranted and ideally suited to properties that require thermal upgrading and aesthetic improvement.
It is manufactured under ISO 9001:2008 and ISO 14001: 2004 Quality and Environmental Management Systems, is fully weather resistant, and can be faced with Alumasc’s range of Silicone or Mineral renders which are available in a choice of textures and colours.

Alumasc’s Swisslab External Wall Insulation (EWI) system has been used as part of the major refurbishment of Quinton’s Court in Needham Market, a mixed use development comprising commercial premises and social housing managed by Suffolk Housing Society.
Converted some years ago from a Victorian warehouse, Quinton’s Court is surrounded by buildings of varying ages and due to its location within the town’s conservation area, the refurbished facade had to replicate the original as closely as possible in order to comply with planning regulations.
Alumasc’s Swisslab system is ideally suited to overcladding existing properties and was recommended for the project as the optimum method of upgrading the façade within the planning guidelines.
The project presented a number of challenges to Alumasc’s Approved Installer Aran Services Ltd, who installed 370m2 of Swisslab with 60mm phenolic insulation onto the solid brick substrate. The building’s use and positioning on a main thoroughfare presented logistical difficulties and works also had to be programmed around window and roofing contractors. The application of the system involved detailing around several difficult-to-access areas above the slate roofs to the rear elevations which were also being re-roofed as part of the refurbishment.
The facade was finished with Alumasc’s M.R. S4 polymer plain render and M.R. S6 masonry paint to match the original look of the building, providing a durable finish less susceptible to cracking and crazing than traditional sand and cement renders.
The completed installation significantly improved the building’s thermal performance from 2.1 w/m2k to a U value of 0.3 w/m2k, whilst upgrading the existing facade in an authentic style in keeping with the surrounding locality.
Swisslab is a BBA Approved and fully warranted system offering a life expectancy in excess of 30 years. It is weather resistant yet vapour permeable and can be faced with Alumasc’s range of Polymer modified renders for a traditional appearance, or Silicone or Mineral renders for a more contemporary look.
