Our UPVC Frame Add-On is a versatile and practical solution for creating extra clearance on door and window frames. Available in 15mm or 20mm thickness and supplied in white only, this high-quality add-on is ideal for a range of applications across UPVC, aluminium, and timber systems.
Frame add-ons are most commonly used on the hinge side of doors to provide the necessary clearance to bypass plaster lines. They are also perfect for window installations, helping frames with trickle vents clear the plaster line, and can be used on conservatories as effective starter or in-fill sections.
Designed to fit multiple systems, this universal add-on is suitable for installers and fabricators working across different frame profiles. The add-ons can also be stacked to achieve greater widths (for example, two 15mm pieces stacked to create a 30mm add-on).
