This report describes the work conducted by the Scottish Energy Centre (SEC) at Edinburgh Napier University for the National Trust of Scotland, measuring the thermal transmittance (U-value), for two types of glazing insulation: shutters and film. The objective was to determine the thermal insulation benefit of these measures when applied to an existing single glazed sash and case window.
