uPVC Vertical Slider Sash Windows Installation Options.
Customisation and Finishing.
You can replace the existing frame architrave with your choice of hardwood, softwood, MDF, PVC-U, or a combination, reflecting your preference. The finished installation may require plaster repairs due to removing the old box sashes, significantly if the original plaster has degraded over time. We ensure the area is ready for you to decorate after installation, as shown by the dark patch.

All uPVC Vertical Slider Sash Windows come with white furniture as standard, which can be changed to Brass, Chrome, or Black.
A child safety lock can be installed for security and child safety devices, as the sash will only open to 100mm.
