Description
The Freefoam FWXI fascia internal corner provides a neat, colour-matched finish where two square fascia runs meet at an internal 90-degree angle. The 300mm trim covers the cut board edges and helps create a clean, consistent finish across the completed roofline.
Manufactured from durable, low-maintenance uPVC, the FWXI is compatible with Freefoam FW 10mm capping fascia and FMS 18mm replacement fascia. It can be measured and cut down on site to suit the width of the boards being installed.

Fascia Internal Corner Colour Options
The FWXI fascia internal corner is stocked in White, Black Ash Woodgrain, Anthracite Grey Woodgrain and Agate Grey Woodgrain. Choose 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 products obtained at different times before installation because minor colour or texture variations can occur between separate 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 FWXI is also suitable for our 18mm replacement fascia boards on full-replacement and new-build roofline installations. Confirm the profile and selected colour before cutting or fixing the trim.
Installing the Fascia Internal Corner
Measure the depth of the adjoining fascia boards and mark the required trim length. Cut the FWXI using a suitable fine-toothed PVC saw, remove any cutting debris and test the corner over both board ends before final installation.
Allow the appropriate expansion clearance between the fascia boards. The corner trim should conceal the joint without preventing the uPVC boards from expanding and contracting as temperatures change.
Avoid rigidly securing both sides in a way that restricts normal thermal movement. Follow the relevant Freefoam installation guidance and accepted trade practice for the fascia system being installed.
Completing a Square Fascia Installation
Combine the FWXI fascia internal corner with matching external corners, straight joiners, double-ended trims and end caps. Using purpose-made, colour-coordinated accessories helps protect exposed edges and gives the roofline a professional finished appearance.
