While it can be fitted over existing sound timber, new installations require a timber backing board to provide the necessary support.

Nails should be spaced no more than 600mm apart to ensure the board remains secure and flat.

Yes, this 175mm board is effective for covering existing window boards to provide a durable, wipe-clean finish.

The board is designed to be color-stable, but like all external UPVC, it may show slight weathering after many years of direct UV exposure.

These boards are intended to be maintenance-free and are finished with a smooth surface; painting is generally not recommended as it may void the intended low-maintenance benefits.

No, fixings such as 50mm Polytop nails must be purchased separately.

Check if fixing centers exceed the 600mm limit; add additional Polytop nails to secure the board closer to the timber backing.

Ensure that the board was installed at the correct temperature or use appropriate joint covers to conceal expansion gaps.

Ensure you are using high-quality Polytop nails specifically designed for UPVC, which feature plastic heads to match the board color and prevent corrosion.
