LOOK FOR THE PATENTED TIMBERWELD® MARK

If you have chosen Bygone Symphony sash windows or Harmony windows with a Timberweld butt joint upgrade, you will now receive the Timberweld mark of authenticity on your windows.

This is an important symbol, confirming that the windows you have received come with patented Timberweld ® technology, exclusively licenced for sash window production to Masterframe, the award winning Bygone manufacturers.

The technology ensures that your new windows are perfectly sealed inside and out and aesthetically authentic enough to impress the planners in conservation areas.  The joints are completely sealed from the elements, with no open chambers to allow in water, draughts and flies – a sound investment!
