Kooltherm wall insulation installed in Dundee residential towers

The tower blocks, originally constructed in the 1950s using a solid concrete no fines wall construction, each comprise of 30 flats.

Following a Green Deal Advice Report (GDAR) undertaken by Sustainable Energy Scotland, it was recommended that an internal wall insulation system was installed to the requirements of PAS 2030 to improve the buildings’ energy efficiency.

Kooltherm Wall Insulation System

All residents were temporarily moved within the blocks for the duration of the upgrades, which were carried out by Abertay Housing Association and local contractor McGill.

The Kingspan Kooltherm Internal Wall Insulation System was specified for the project, requiring 82.5mm and 32.5mm of Kingspan Kooltherm K18 Insulated Plasterboard to be installed on a new timber batten frame inside of the external walls.

All internal partition walls were also lined with 32.5mm of the insulated plasterboard.

In addition to this, Kinspan Kooltherm K10 Soffit Board was applied to the ceiling to provide the maximum insulation values to each individual room.

Both boards offer thermal conductivities as low as 0.020 W/m.K, featuring a fibre-free core and manufactured with a blowing agent, which has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

They are certified ‘Very Good’ under the demanding BES 6001: Responsible Sourcing of Construction Products standard and have a Green Guide rating of A .

Eco friendly housing

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 added: “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.”
