Description
The Freefoam FWFXI 135 degree internal corner provides a neat, colour-matched finish where two square fascia runs meet at an internal 135-degree angle. The 300mm trim covers exposed board edges and is suitable for angled roofline sections where a standard 90-degree internal corner cannot be used.
Manufactured from durable, low-maintenance uPVC, the FWFXI is compatible with Freefoam FW 10mm capping fascia and FMS 18mm replacement fascia. It can be measured and cut down on site to match the depth of the adjoining fascia boards.

135 Degree Internal Corner Colours
The FWFXI 135 degree internal corner is stocked in White, Black Ash Woodgrain, Anthracite Grey Woodgrain and Agate Grey Woodgrain. Select the required finish from the colour menu before adding the product to your basket.
Match the corner to the adjoining fascia boards wherever possible. Compare components obtained at different times before installation because minor variations in shade or woodgrain texture can occur between manufacturing batches.
Compatible Square Fascia Boards
Use this internal corner with our 10mm capping fascia boards when covering an existing sound timber fascia or an appropriate backing board.
The FWFXI can also be used with our 18mm replacement fascia boards on full-replacement and new-build installations. Confirm the fascia profile, corner angle and selected colour before cutting.
Installing the 135 Degree Internal Corner
Measure the depth of both fascia boards and mark the required length on the corner trim. Cut the FWFXI using a suitable fine-toothed PVC saw, remove any cutting debris and test the trim against both board ends before completing the installation.
Leave the appropriate clearance between the adjoining fascia boards for normal uPVC expansion and contraction. The corner should conceal the joint without locking the boards together or preventing thermal movement.
Avoid rigidly securing both sides in a way that restricts movement. Follow the applicable Freefoam installation instructions and accepted trade practice for the fascia system being installed.
Completing an Angled Fascia Installation
Combine the FWFXI 135 degree internal corner with matching external corners, straight joiners, 90-degree corners and end caps. Colour-coordinated accessories help conceal exposed edges and create a consistent appearance across complex roofline shapes.
