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.
Dual colouring lets you have both sides of your window frames coloured or have a clean white interior frame.
