Product Information

Full details

The Freefoam 175mm Fascia Capping Board (FW175) is designed for contractors and DIY homeowners seeking a low-maintenance, durable solution for exterior roofline finishing or covering aged timber window boards. Its primary benefit lies in its ability to provide a clean, long-lasting aesthetic without the recurring need for painting or rot repair; however, users should note that in new build scenarios, this 10mm board requires a secondary timber backing to ensure sufficient structural rigidity.

Extended Product Information

FAQs

Can I use this board without timber backing?

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

What is the recommended nail spacing?

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

Is this product suitable for window sills?

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

Does the UPVC material fade over time?

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.

Can I paint these boards?

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.

Are the nails included?

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

Troubleshooting

Board appearing wavy or bowed

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

Visible gaps between board joints

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

Nail heads rusting or visible

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

Pros and Cons

Pros

  • Significantly reduces maintenance compared to timber
  • Easy to install over existing structures
  • Provides a clean, professional finish
  • Highly resistant to moisture and rot
  • Standardized size fits common architectural requirements

Cons

  • Requires timber backing for structural support in new builds
  • Not intended for load-bearing applications
  • UPVC may expand or contract with extreme temperature shifts

Setup, Compatibility & Care

Installation should be executed with precision to maintain the longevity of the product. When fastening the boards, use 2 x 50mm Polytop Nails at every fixing point. It is critical to space these nails no more than 600mm apart to prevent sagging or oil-canning of the plastic surface. When working with UPVC, remember that it reacts to thermal expansion; leave slight gaps at joints if required by local building practices. For cleaning, simply wipe the surface with a soft cloth and mild soapy water periodically to remove debris and maintain its appearance. Avoid abrasive cleaners or solvents that may damage the smooth exterior finish.
