Description
The Freefoam FWJJ fascia double joiner provides a clean, colour-matched cover where two square fascia boards meet. Its 600mm double-ended design can be cut down on site, making it suitable for joining fascia across deeper roofline sections and box-end details.
Manufactured from durable, low-maintenance uPVC, the FWJJ is compatible with Freefoam FW 10mm capping fascia and FMS 18mm replacement fascia. It covers the expansion gap between adjoining boards while maintaining a neat and consistent roofline finish.

Fascia Double Joiner Colour Options
The FWJJ fascia double joiner 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 joiner to the adjoining fascia boards wherever possible. Check products obtained at different times before installation because minor variations can occur between separate manufacturing batches.
Compatible Square Fascia Boards
Use this fascia double joiner with our 10mm capping fascia boards when covering an existing sound timber fascia or an appropriate backing board.
The FWJJ can also be used with our 18mm replacement fascia boards on full-replacement and new-build roofline installations.
Installing the Fascia Double Joiner
Measure the fascia depth and mark the required joiner length before cutting. Use a suitable fine-toothed PVC saw to obtain a clean edge, remove cutting debris and test the trim over the joint before completing the installation.
Leave the appropriate expansion gap between adjoining fascia boards. The joiner should conceal this gap without preventing the boards from expanding and contracting as temperatures change.
A common installation method is to secure one side of the joint while allowing controlled movement on the other. Follow the applicable Freefoam installation guidance and good trade practice for the selected fascia system.
Completing the Fascia Installation
Combine the FWJJ fascia double joiner with matching external corners, internal corners and end caps from the Freefoam square fascia accessory range. Using colour-coordinated accessories helps protect exposed edges and provides a consistent finished appearance across the roofline.
