Technical Paper 23

Overview

This report examines two inexpensive methods for improving the thermal performance of single glazed sash and case windows; the use of insulated shutters, and a window film applied to the existing panes. Both techniques were trialled at Wee Causeway, a detached 18th century cottage in Culross, with the success of each approach analysed in relation to thermal transmittance measurements taken in-situ, together with those calculated using proprietary software programmes.
