Also, please note those well and truly air-tight stormglazing panels affixed to the lights of the windows! The National Heritage Council produced a book on conservation of stained glass recently – by David Lawrence – and this process is regarded as “discredited”. So much for conservation…..

I haven’t seen or have access to that book by David Lawrence, does he condemn all types of storm glazing for leaded – stained glass windows? even the type we see on most churches that have air-vents (spider heaven) or just these ‘air tight panels’ that have no adequate form of ventilation?
I’m presuming that a build up of condensation is the main problem with any sort of ‘air tight’ storm glazing.
