Premium performance insulation from Kingspan Insulation has been used in the £3.5m refurbishment of the four 10-storey tower blocks in Dundee known as Dryburgh Gardens.
Each block comprises 30 flats, 81 of which are owned by Abertay Housing Association whilst the remaining 39 are privately owned.
The tower blocks were originally built in the 1950s using a solid concrete no fines wall construction. Following a Green Deal Advice Report (GDAR) undertaken by Sustainable Energy Scotland, the recommended measure for improving the energy efficiency of the buildings was the installation of internal wall insulation systems to the stringent requirements of PAS 2030.
Local contractor, McGill, was appointed as the main contractor for the project by Abertay Housing Association, whilst FBN (Glasgow) provided all the architectural services.
All residents were moved to temporary accommodation within the blocks for the duration of the upgrade works, which required each property to be completely stripped out, including the kitchens and bathrooms. Tenants should expect to see a reduction in their heating bills whilst also feeling much more comfortable in their homes.
The Kingspan Kooltherm Internal Wall Insulation System that was selected for the job, required 82.5mm and 32.5mm Kingspan Kooltherm K18 Insulated Plasterboard to be installed on a new timber batten frame to the inside of all external walls, whilst all internal partition walls were lined with 32.5mm Kingspan Kooltherm K18 Insulated Plasterboard. 25mm Kingspan Kooltherm K10 Soffit Board was also applied to the ceiling to provide the maximum insulation values to each individual room.
Bob Sander, Operations Director for Abertay Housing Association commented “We were delighted to secure substantial eco funding for this project; the largest Abertay Housing Association has ever delivered, so that our tenants benefit from homes that meet SHQS Scottish Housing Quality Standard 2015 and importantly, are easy and affordable to keep warm.”
Richard Hands of FBN commented “The retrofit met the original feasibility design targets we set of raising the EPC ratings for all flats from an F rating up to a B. This should dramatically reduce the tenant’s energy bills and meet the recommendations of the Energy Saving Trust for all homes to reach a B standard by 2050.”
Both Kingspan Kooltherm K18 Insulated Plasterboard and Kingspan Kooltherm K10 Soffit Board offer outstanding performance with thermal conductivities as low as 0.020 W/m.K. The products feature a fibre-free core and are manufactured with a blowing agent, which has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
Both these products are certified ‘Very Good’ under the demanding BES 6001: Responsible Sourcing of Construction Products standard and have a Green Guide rating of A+.
