Technical Paper 20

Historic Scotland Technical Paper 20 presents the results from thermal in-situ testing of slim-profile double glazing. During the winter 2009/2010, Changeworks led a pilot project, Double Glazing in Listed Buildings, installing a range of slim-profile double-glazing systems into category ‘B’ listed, Georgian tenement buildings in Edinburgh’s Old Town. As part of that project, published as Historic Scotland Technical Paper 9, the thermal performance of all glazing units was measured and the embodied energy associated with them was investigated. That project answered most of the questions surrounding double-glazing in listed buildings, except for the longevity of the glazing units. In 2011, it was, therefore, decided to re-measure in situ the thermal performance of the units, which by then would have been in place for two years. This report, Historic Scotland Technical Paper 20, presents, and draws conclusions from, the comparison of the U-value results measured in the winters of 2009/10 and 2011/12.
