Description
Freefoam 5m uPVC J Trim / Soffit Starter & Edge Trim – 30mm x 10mm – All Colours
The Freefoam F107 uPVC J Trim is a 5 metre starter and edge trim used to create a clean finished edge around compatible Freefoam soffit installations. Rather than joining two boards together like the F106 H-section joint, this J-shaped profile receives the edge of a soffit board where the installation starts, finishes or terminates against another surface.
It is suitable for use with Freefoam General Purpose Soffit Board and Hollow Soffit, making it a useful finishing trim for new rooflines, replacement soffits, extensions and other eaves work.
Why Use the Freefoam F107 J Trim?
-
Finishes exposed soffit board edges

No painting, staining or timber treatment required.
What Is a J Trim Actually Used For?
The easiest way to think about the F107 is as an edge finishing channel. The soffit board slides into the J-shaped section, hiding the cut edge and giving the perimeter of the soffit a much tidier appearance.
Typical locations include the rear edge of the soffit near the external wall, the beginning or end of a soffit run, and other details where a board edge needs to be neatly enclosed.
J Trim vs Soffit Joint Trim
-
F107 J Trim
Used at the edge, start or termination of a soffit board. -
F106 Soffit Joint / H Joiner
Used where two soffit boards meet end-to-end along a straight run.
They perform different jobs, so a J trim should not be used as a substitute for a straight soffit joiner.
Installation Tips
- Measure and cut the J trim to the required roofline length.
- Fix the trim securely to the supporting structure before inserting the soffit board.
- Slide the edge of the soffit into the J-section for a neat concealed finish.
- Allow appropriate clearance for normal uPVC expansion and contraction.
- Keep the trim straight during fixing so the finished soffit edge remains consistent along the roof run.

Frequently Asked Questions
Is this used to join two soffit boards together?
No. For a straight board-to-board connection, use the Freefoam F106 soffit joint trim. The F107 is primarily a starter and edge finishing trim.
Can I use it with Hollow Soffit?
Yes. Freefoam specifies the F107 J-section trim for use with both General Purpose Board and Hollow Soffit.
Can the 5m trim be shortened?
Yes. It can be cut on site to suit the required roofline length or individual detail.
Is this only a soffit trim?
The F107 is a universal Freefoam J-section profile and can also be used in certain compatible cladding details, but for roofline work its main role is as a soffit starter and edge trim.
A Simple Trim That Makes the Soffit Look Finished
The Freefoam F107 5m J Trim is one of those small roofline components that makes a noticeable difference to the finished job. It neatly encloses soffit board edges, provides a proper starting or finishing channel and helps produce the clean, straight perimeter expected from a professional uPVC soffit installation.
