Dear Ian

Over the years there has been much debate about best practice when it comes to heritage glazing and by that I mean windows that are specified with a narrow cavity or reduced sightline IGU. These are often a requirement for the replacement and refurbishment of windows in conservation areas, listed buildings and in Article 4 areas of designation.

At Hodgson Sealants it has long been understood that our obligations as a manufacturer extend well beyond the provision of high quality products. In this instance our main aim is to give guidance to anyone involved in the selection and provision of glazed timber windows. This is with particular emphasis on the selection of suitable glazing systems for use with all glass types and the workmanship standards needed to maximise their performance and extend their service life.

Due to our unique position in the timber glazing market, we are often asked for advice on how to best glaze these into timber frames, especially when glazing in conservation areas where the appearance of a traditional putty finish is required. Our response in line with that of the GGF is that the ‘glazing method employed should be based on the IGU manufacturers recommendations.’ Although it is noted that with reduced sightline IGU’s, it may not be possible to meet all of the requirements of the GGF Datasheet 4.2.

By working closely with IGU manufacturers and their component suppliers, including edge sealant suppliers, we have helped with the provision of glazing methods which give the manufacturer confidence that compatible materials and sound methods are being employed to install their product.

Our customers, installers and also our partners endorse our glazing method, but ultimately, we’re here to fully support companies in the sector who need this expert assistance for heritage glazing.

Yours sincerely
