Full Mechanical Joints
The fully mechanical joints take authenticity to another level because the 45° uPVC welds on the sash are replaced with 90° mechanical joints as found on traditional timber windows.
Standard 45° Welded Sash
The standard design features a mechanical outer frame paired with 45° welded sash corners, offering a seamless, durable joint that mimics the look of timber while ensuring lasting strength.
