Description
The Freefoam 300mm 135° Square uPVC Fascia Internal Corner Trim is designed to finish inward-facing angled roofline corners where two compatible square fascia runs meet at 135 degrees. It covers the meeting point between the boards, concealing cut edges and creating a neat, colour-matched transition through the angled section of the roofline.
This is the internal version of the 135° fascia corner. It is used on recessed or inward-facing angles and should not be confused with the separate 135° external corner trim used around projecting outside corners.
What Is This 135° Internal Corner Used For?
-
135° internal roofline junctions
Purpose-made for fascia runs that meet inside a shallow, angled corner rather than a standard square 90° corner. -
Splayed and angled building details
Useful on properties with non-square extensions, bay-style roof details and other angled rooflines. -
Covers fascia board ends
Hides the cut edges where the two boards meet and gives the junction a much cleaner finished appearance. -
Matches compatible Freefoam square fascia
Available in coordinating finishes so the corner blends naturally with the surrounding roofline.
135° Internal vs 135° External Corner
-
135° Internal Corner
Used where two fascia runs meet inside an inward-facing or recessed angled corner. -
135° External Corner
Used where fascia wraps around a projecting outward-facing angled corner. -
90° Internal Corner
Used where the recessed corner is a conventional square angle rather than 135°.
The internal and external trims can look very similar in product images, but their profiles are formed in opposite directions and they are not interchangeable.
Why Use the Correct Angled Fascia Trim?
-
Purpose-made 135° profile
Fits the angle properly rather than trying to adapt a standard 90° corner. -
Cleaner finished roofline
Conceals board joints and exposed cuts around an awkward change in direction. -
300mm length
Provides useful coverage across standard fascia depths and can be trimmed on site where required. -
Low-maintenance uPVC
No painting or staining is required. -
Colour-matched finish
Helps keep the roofline visually consistent through the angled corner.
Available Colours
- White
- Anthracite Grey Foil
- Black Ash
- Light Oak

Where Would You Typically Need One?
Most straightforward rooflines use 90° corners, but not every property is built on square lines. Where an extension, bay or other part of the building creates a shallower internal angle, this 135° trim allows the fascia to follow that shape neatly.
Using the correct pre-formed corner is much easier than trying to fabricate the detail from straight fascia trims, and gives the finished installation a more professional appearance.
Frequently Asked Questions
Is this the same as the 135° external fascia corner?
No. This is shaped for an inward-facing angled corner. The external version is designed for a projecting outside corner.
Is this for a standard 90° internal corner?
No. Freefoam offers a separate 90° internal corner trim. This product is specifically formed for 135° roofline angles.
What does the 300mm measurement refer to?
It is the length of the fascia corner trim. It can be cut down where required to suit the fascia depth.
Can I use it with coloured fascia?
Yes. Choose the corresponding finish to match compatible Freefoam square fascia boards.
The Correct Finish for Angled Internal Corners
The Freefoam 300mm 135° Square uPVC Fascia Internal Corner Trim is a small but important accessory where a roofline turns through a non-standard inward angle. It follows the 135° junction correctly, covers the fascia board ends and keeps the finished roofline neat and consistent.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
