Alumasc deliver thermal success in Goole

Posted by nicola perrins

The Kingsway refurbishment project in the Goole area of Yorkshire comprises a selection of social housing properties, owned and maintained by East Riding of Yorkshire Council.

Goole102 properties were selected by the Council for exterior refurbishment, to improve thermal performance and to visually regenerate the area and maximise the lifespan of the properties.

Alumasc’s Swisslab EWI system was specified for all property elevations, using 120mm Kooltherm phenolic insulation. This decision was based on the Council’s successful use of Swisslab on previous schemes and the ongoing technical support provided by Alumasc to meet the challenges of the project.

The ambitious energy efficiency improvements required, could only be achieved by using 120mm Kooltherm phenolic board. Other insulation options available for use with Swisslab would have been too thick. With the specification of this system, East Riding of Yorkshire Council has far exceeded the requirements of most local authorities, leading to ‘U’ values of around 0.15W/m2K – far lower than most results achieved using other insulation thicknesses.

The properties were a complex mix of ages, styles and sizes, including detached properties c1800, terraced homes c1900 and semi-detached houses constructed in the 1950s. The period properties presented the challenge of maintaining their features and character and some of the homes had been subject to multiple extensions over the years, meaning significant works were needed to ensure a fluid and seamless finish.

Goole3_Before&AfterA combination of Alumasc’s brick-effect render (M.R. Rendabrick) and Silkolitt silicone render was determined by the surrounding properties to ensure those being refurbished blended in.

Considerable attention was required at one particular property where differing land levels meant side streets sloped down past the house. Alumasc worked closely with Westdale to find a solution which involved a combination of Swisslab being installed to pavement level and Alumasc’s M.R. S2 used below the damp proof course level to avoid bridging the property’s dpc with a non-porous material.
