Project Headline: Project involved installing EWI to 23 Swedish Timber and Scan system houses which are of single skin timber frame construction and classed as hard to treat properties

Project Description:

The properties selected under this project already had ASHPs installed as part of previous works funded by other project partners. The ASHPs were installed first to avoid damaging the new EWI system.

By installing EWI alongside the ASHPs, the insulation will help maximise the benefits of the upgraded clean heating systems, already installed. Alongside this, the upgraded fabric improvements will bring a new clean finish to the façade of the properties. This has not only greatly improved the u-values but the visual aspect of the properties. The installation of these measures will guarantee lower emissions and lower energy costs for tenants.

There are many similar timber frame houses throughout Scotland which are classed as hard to treat. This project aimed to create an exemplar project that could be replicated across the housing archetype.
