Secondary Glazing for Listed, Residential and Commercial Properties


Our staff have installed secondary glazing frames in hundreds of  listed residential properties, commercial buildings and churches in Oxfordshire and surrounding counties for over 25 years.

Secondary glazing is an extremely cost-effective means of improving thermal insulation and reducing noise pollution in both listed residential; other residential and commercial properties with single-glazed windows.

Since mid 2021, there has been a substantial increase in demand for secondary glazing. Notable recent secondary glazing installations include The Oxford Playhouse theatre building; Green Templeton College Library and the Kelmscott Manor estate. We average 3 to 4 residential installations per month and hence our expertise is unrivalled.

The frame is fitted inside the window reveal and made to match the exterior frame, whether a single casement, fixed window, sash window etc. The whole point of correct installation is to make the secondary frame as invisible as possible within the window reveal. You will need a very careful look at the photographs to see them.

Secondary glazing is especially suitable for customers living in Listed Buildings where conventional double glazing is not permitted.

Glazing options include toughened low-e safety glass or noise reduction glass for customers living near busy roads to almost eliminate traffic noise.

Site visits and quotations are free-of charge. Please telephone for further technical information.

“We installed secondary glazing in a Grade 2 listed cottage we recently bought and we are delighted with the result. The building is over three hundred years old so the windows were difficult to fit, but Oxfordshire Glass have done a brilliant job.

My son remarked on the immediate improvement in temperature in a room that had been permanently cold. Furthermore the glazing is easy to remove for cleaning (imperative in spidery environments) and when you do notice it, it looks attractive. I am happy to recommend this company without hesitation to other customers."

“Secondary glazing to a listed cottage. Very pleased with the result. Very happy with the service and the fitters were polite, efficient and cleaned up afterwards. Would recommend."

“We had an excellent experience with Oxfordshire Glass. They installed several windows for us and did an excellent job. It was no trouble to them to come back afterwards and adjust a couple of things”.
