Dryburgh Gardens, Dundee

Internal Wall Insulation

Dryburgh Gardens

Dryburgh Gardens is a sheltered housing scheme in Dundee, with 81 properties owned by Abertay Housing Association and 39 owned privately. GoSustainable were able to secure 3x the level of funding thought achievable to support the energy efficiency upgrade to all properties with internal wall insulation.

Assessment & Recommendation

GoSustainable carried out a Green Deal Advice Report (GDAR) to assess the viability of energy efficiency measures. The report is in two parts:

1. Technical Survey

We completed a chartered surveyor’s report and a full technical survey of the property and produced an Energy Performance Certificate (EPC) identifying the current and potential energy efficiency of the property. We then identified a range of measures that could be introduced to improve the energy efficiency of the property and the associated costs to implement these.

Recommended measures:

2. ECO Report

This report helps to identify the annual cost savings to the home depending on the energy efficiency measures introduced. This determines the level of financial support available through the Energy Company Obligation (ECO), part of the government’s commitment to reduce carbon emissions.

The Internal wall insulation measure forecast the following savings per flat:

Annual x36 years
product lifetime
Carbon Saving (tonnes) 2.814 75.978
Cost Saving £394.94 £14.218
Insulation - Internal Wall Insulation - Fitting


The residents are provided with temporary accommodation while the complete refit project takes place.

Each property is completely stripped out including kitchens and bathrooms. The GoSustainable team then take out all existing external wall linings back to the ‘No Fines’ substrate of the building in preparation for the new insulation system installation. All ceilings and floors are cut back 600mm around the perimeter to allow for new insulation measures to prevent any cold bridging.

Kingspan K18 (102.5mm) is installed on new timber batten frame to all external walls. 600mm perimeter of a ceiling is insulated with 25mm Kingspan K10 board then the plasterboard is reinstated. 600mm perimeter of floors is insulated with 50mm Knauf DriTherm, sealed with VCL then the floorboards are reinstated.

Internal partition walls are lined with Kingspan K18 (32.5mm) to provide maximum insulation values to each individual room.

The main contractor then fits a new kitchen and bathroom, double glazing and a dual immersion water tank before fitting carpets and redecorating ready for the tenant to move back in.


This large-scale project is work in progress. Substantial ECO funding was secured for the client. So far we have completed 40 properties. Tenant feedback has been very positive in both the new environment they are in and the noticeable improved thermal comfort.

Resident Mrs Peters commented:

“It is so much warmer and I am really pleased with my new home”.

Resident Mrs Zanre commented:

“My flat is so much cosier and a lot brighter than before”.

We are delighted to have secured substantial eco funding for this project; the largest Abertay Housing Association has ever delivered, so that our tenants benefit from homes that meet the Scottish Quality Homes Standard (SQHS), and importantly, are easy and affordable to keep warm.
