This projects seeks to improve the thermal and airtightness performance of the suspended timber floor of a ground floor interwar flat, owned by Govanhill Housing Asscociation. Identifying heat loss and draughts through the floors was one of the main findings of the preliminary on-site measurements. Having effective tactics to reduce heat loss and draughts through ground floors, whilst avoiding decanting of tenants, would be of significant benefit to the Housing Association’s maintenance upgrade programme. Potential benefits to other partners would also be huge and may include compliance with EESSH regulations on ground floor flats which otherwise require decanting and/or significant work costs. We are currently monitoring the results of this work.
