Timberweld® is a patented method of welding PVC-U frames which creates an authentic timber butt-joint effect – on both sides of the window, inside and out. Alan Burgess (who designed the UK’s first dedicated PVC-U box sash in 1984 and is credited with creating the PVC-U sliding sash market) and Masterframe Technical Director Ray Rabett, are the innovators behind the Timberweld technology.
