Historic Scotland Refurbishment Case Studies: Sword Street, Glasgow – Internal wall insulation to six tenement flats

This report is the fourth in a series of Refurbishment Case Studies that describe site trials carried out by Historic Scotland. As with the others produced to date, the aim of the project described here was to examine methods and materials that could be used to improve the thermal performance of traditionally constructed buildings. There was a desire, where possible, to use materials which were natural and vapour permeable to help maintain the performance of mass masonry walls. In this trial, work was carried out only to the walls, as the principal aim was to demonstrate that the thermal performance of mass masonry walls could be upgraded whilst still retaining water vapour movement through the building fabric. This case study therefore examines two measures of performance - the improvement in thermal properties and the assessment moisture levels within the walls following the installation of the insulation measures. Five different insulation materials were used in the trial in order to provide comparative data to compare relative improvements in thermal performance. Published in 2012

As a clear comparison between wall insulation products that do not require the use of a vapour barrier this is an excellent resource. The range of insulation products tested illustrate the most cost effective option, the most space-saving and the best U-value improver. The only information missing is pre-intervention moisture levels within the existing masonry for comparison.
