The push to insulate our homes due to rising cost of energy, but also the challenge of climate change, is rightly pointing a spotlight on draughty sashes and casements.
This two-day conference and evening gathering, supported by SPAB, brings together experts in the history, repair and retrofit of historic windows, and the design and manufacture of new joinery. It will be of interest to anyone who would like to join the debate and understand more.
Understanding the history and significance of windows
Clues for dating windows based on physical evidence
Historic glass and modern glazing systems
Specifying repair, and paint finishes
The science of heat loss and retrofitting existing windows
Justifying the case for replacement, and looking at the options

A number of sponsors will also be exhibiting and demonstrating their services and products.
