Swisspan External Wall Insulation (EWI) from Alumasc has been used in a major social housing refurbishment project that is already changing the lives of its tenants.
Managed by Merseyside-based housing association Helena Partnerships, the scheme, in the Moss Bank area of St Helens, comprises 107 British Iron and Steel Federation (BISF) homes, well known for their poor thermal insulation and environmental performance. EWI makes a significant contribution to thermal efficiency and aesthetics, and as such, was a key element in Helena’s proposed programme of works, which also included new windows, doors and solar panels.
Following intensive research into the choice of systems and manufacturers available, Helena’s design team specified Alumasc’s Swisspan EWI system incorporating 100mm of Kingspan Kooltherm® K5 External Wall Board insulation, which was installed to the ground and first floor walls by Alumasc’s Approved Installer Forrest of Preston.
The Swisspan system is used regularly for upgrading social housing to meet the Decent Homes Standard and non-traditional, “hard to treat” properties such as BISF, Cornish, Crudens, Unity and Airey. When used with Kingspan Kooltherm® K5, the result is a high performance, fully weather resistant and energy efficient façade. Since the refurbishment, the U-value of the properties has reduced from 2.09W/m2.K to 0.257W/m2.K, significantly reducing the cost of fuel bills.The existing cladding systems at Moss Bank were non-structural; therefore the load of the new EWI system had to be directed to the structural stanchions of the properties. By design, Alumasc’s BBA Approved Swisspan EWI system is ideally suited to this type of application due to a horizontal galvanized steel rail system that can be mechanically fixed to the structural elements of the building, providing support for the insulation panels. Swisspan is also fully warranted, weather resistant and vapour permeable, offering a range of attractive render finishes including aggregate dashed, textured and coloured coatings.
