Heritage windows and doors for listed and period buildings offer modern day performance without compromising the timeless looks of older buildings.
At Gowercroft our double glazed wooden Heritage Windows and Doors are made with ultra thin double glazed units and are hand build to exacting standards in our Workshop in Alfreton. All our products come with a minimum 10 year guarantee and meet the highest levels of style and performance to give you years of maintenance free service.

What are Heritage Windows and Doors?

Heritage windows are windows and doors designed and built to fit seamlessly into listed buildings. Many older buildings that were built when window technology was less advanced than it is today feature much smaller windows. Most old-fashioned windows were built up from many smaller panes held together with criss-crossing wooden frames. This is because glass manufacture at the time could only produce tall, thin panes without them breaking during the production process as all glass at the time was blown by hand. Interesting note – glass panes were made by shearing blown glass. This left a piece of glass with a bulge, the bottom of the ‘bottle’ the pane was cut from. This was known as the ‘bullseye’ and they were sold as cheaper panes. Of course, bullseyes are now synonymous with Olde England and the traditional English pub.

Older windows are much thinner than modern windows. This makes it difficult to make more efficient windows as double glazing. Fortunately new techniques in double glazing manufacture have given us vacuum cavity units that offer greater efficiency in a much slimmer unit. This means that historic buildings can now enjoy better heat retention and noise reduction without compromising their timeless looks. We have more information on the problems associated with slim double glazing units in heritage windows .

Gowercroft exclusively use Pilkington Spacia glass in our heritage windows for improved performance and length of service life. You can read more about Pilkington Spacia Glass here or visit the Pilkington site for more .
