To ensure proper system expansion and contraction across varying temperatures, one side of the joint or corner in any PVC fascia installation must be glued to the board, while the other side should be sealed with low modulus silicon to facilitate movement. The double ended joints can be easily cut to size using a standard hacksaw or a fine toothed saw.

The Freefoam Fascia Double End Joint Trim is designed for professional roofline installers and DIY enthusiasts who need a clean, aesthetic finish for anthracite grey fascia board installations. This component is essential for concealing the 10mm expansion gaps necessary for structural integrity; however, users must strictly adhere to specific bonding techniques on only one side of the joint to prevent warping caused by thermal expansion.

FAQs
Why is it important to glue only one side of the joint?
Plastic fascia boards expand and contract with temperature changes. Gluing both sides prevents this movement, which can cause the boards to buckle or the joints to snap.
Can I use standard superglue to fix the trim?
No. Use a professional-grade PVC adhesive on the fixed side and a low-modulus silicone on the sliding side to ensure proper structural movement.
What tools do I need to cut the trim?
A standard hacksaw or a fine-toothed hand saw is sufficient for cutting the PVC material accurately.
Is this trim suitable for all fascia types?
It is designed for standard PVC fascia boards. Ensure your installation allows for the required 10mm expansion gap.
How do I clean the anthracite grey finish?
Use a soft cloth and mild soapy water. Avoid abrasive sponges or harsh chemicals that could scratch or fade the colored surface.
Troubleshooting
Joint is buckling or popping off the boards
Check if both sides were glued. Only one side should be glued; the other must allow for thermal movement.
Water is leaking behind the fascia
Ensure the low-modulus silicone sealant is correctly applied to the sliding side of the joint and that there are no gaps.
Trim does not match the fascia board depth
Verify that your board height is compatible with the 47mm trim profile before installation.

Setup, Compatibility & Care
Measuring: Measure the height of your existing fascia boards to ensure the 47mm profile provides adequate coverage.
Cutting: Use a fine-toothed saw for a clean edge. If necessary, sand the cut edge lightly with fine-grit sandpaper to remove burrs.
Application: Clean the surface of the fascia boards to remove dust or grease before applying bonding agents.
Fixing: Always remember the golden rule: glue one side only. Use low-modulus silicone on the other side to allow for movement.
Maintenance: Periodically inspect the joints to ensure that the silicone seal remains intact. Clean with a damp, soft cloth using mild soapy water; avoid abrasive cleaners or solvent-based chemicals that could damage the Anthracite Grey finish.
