Sash & Window Manufacturing

Preservation Windows offer a broad range of sash & case window styles, including Georgian and Victorian.  We are committed to not only providing top quality sash & case windows to our customers, both residential and commercial, but also approach the process in a sound, responsible and sustainable manner by sourcing materials that are approved by the Forest Stewardship Council (FSC). This ensures that not only is the beauty of the sash & case windows attained, but also that a minimised impact on the environment and our precious forestry resources are sustainably managed.  We believe that the maintenance and preservation of original historic exterior materials should be encouraged.   Replacement windows are not a recommended treatment for historic buildings. The replacement of windows frequently compromises the aesthetic integrity of a building through the removal of original architectural details and the alteration of the building’s historic character and visual identification with a particular period or style.  Our company’s window preservation policy was developed to encourage preservation and to aid our customers in selecting appropriate treatment for their proposed option.

Wooden and Timber Windows

Within the manufacture of wooden windows, timber windows and frames, our tradesmen use only the highest quality materials throughout the manufacturing process. We also manufacture bespoke, casement, curved, arched head and stained glass windows along with hardwood conservatories. All materials are carefully sourced from the FSC, this includes hardwood known as Meranti, an extremely versatile and long lasting wood for use in a variety of applications.  Sash & case windows are a prominent feature in many of our buildings, homes and offices in central Scotland.  Our tradesmen use traditional joinery techniques to manufacture our windows.  This ensures that our windows will outlast their modern equivalents. Our use of specialised FSC approved timber adds longevity to our window products and provides lasting quality for every client who uses our service.
