Protective glazing for historic stained glass

We are currently working with Historic England on a research project investigating the use of protective glazing as part of the approach to the conservation of historic stained glass. Topics under discussion are the current state of understanding of protective glazing (including an extensive literature review), the impact of microbiological growth on the deterioration of stained glass and the controlling influence of protective glazing, the effect on functionality of variation in design details, including interspace and vent geometry (for which an extensive CFD modelling study has been undertaken), as well as the aesthetic impact of different approaches to protective glazing. The aim is to provide information to assist with the evaluation of the risks and benefits of the use of protective glazing in specific cases. Project partners include Historic England, Element Energy and the Canterbury Cathedral Stained Glass Department. The work is expected to be published as an Historic England research transaction and as an Advisory Note later in 2017. The project included a translation of a key text on microbiological deterioration of stained glass, which is now available via the CVMA website

Practical Building Conservation, Building Environment

Building Environment, the sixth volume of the Historic England Practical Building Conservation series has now been published. Co-edited by Robyn Pender, Brian Ridout and Tobit Curteis the book covers topics from the basic physics of water behaviour in building materials to environmental investigations and monitoring and practical approaches to the repair of the building and rainwater disposal system. Aimed at the building professional and the interested client, the book draws together much of the research conducted in the field over recent decades into a single book, which is intended, as the series title indicates, to provide a tool for practical building conservation.

Heritage Lottery Fund environmental assessment

In 2015 we were commisioned by the Heritage Lottery Fund to develop advice for applicants on how to assess the effect of building performance and environment on projects involving the development of historic buildings. Many projects have an unintended effect on the building environment risking damage to the historic fabric, which can require modifications to the project design at a late stage. The advisory document provides applicants with the tools to assess the risk involved and allow mitigation measures to be built into the project at the earliest stage. The guidance document was published in 2017 alongside an introductory article which are both available on our Publications page.

Historic England environmental survey guidance

We are currently working with Historic England on the development of environmental survey and assessment guidelines for those involved in historic building conservation or development projects including professional adviors, conservators, owners and funding bodies, to provide guidance on best practice for assessment of environmental deterioration and developing practical and effective control measures. It is anticipated that this will be published in 2018.
