This three-hour webinar explores the history, design and conservation of historic Irish windows, with an emphasis on the timber sash tradition, with two expert speakers from academic/technical and joinery trade perspectives.

Dr Nessa Roche leads attendees through the history and evolution of Irish windows, provincial and vernacular design details. She explores influences on design and glazing, and discuss approaches to best practice conservation and opportunities for thermal upgrading. Joiner Gary Beirne develops these themes with a focus on common defects, repair techniques, ‘combination’ windows that utilise multiple materials, painting and decorating, site logistics and glazing. Both lectures include documentary sources, regional variations, guidance references and case studies.
