Smooth weld flush and sculptured sash uPVC window frames

uPVC standard and smooth weld difference

Standard vs smooth

The corner joints of our high quality uPVC window frames are manufacturered to look like traditional wood window frames.

This is achieved by pushing the leftover plastic into the profile creating a smooth joint rather than the wider corner welds typically seen on standard uPVC window frames.

Smooth weld joints are perfect for woodgrain or colour finished window frames

Our premium window frames are available in 26 different colourways from stock. Don't worry if you’re looking for a specific colour - There’s also practically hundreds of Renolit colour finishes you can choose from.
