Fitting and Usage

UPVC Laminated Window Internal Joint Diagram

If necessary cut your joint to the correct size, and superglue the inside and place firmly onto the board. Repeat on the other side.

If you need to retro-fit your joint, you may have to trim the underside for correct fitting.

Top Tip: When gluing, we recommend using an activator for a quick dry solution.
