FAQs

Are these caps sold as a set?

Yes, this set includes a pair of caps suitable for the left and right ends of the window cill.

Can I use these on timber cills?

These are designed specifically for PVC cill profiles and may not provide a secure fit or proper seal on timber.

Do I need special tools to install them?

No special tools are required, though a small amount of plastic adhesive is recommended for a secure fix.

Are these caps weather-resistant?

Yes, they are manufactured from durable PVC designed to handle external environmental conditions.

Can the caps be painted?

While they come in a clean white finish, painting is generally not recommended as the surface is designed to be weather-resistant and may not hold paint well.

Troubleshooting

Cap feels loose or falls off

Ensure the cill surface was cleaned of dust before application; re-apply using a stronger, exterior-grade PVC adhesive.

Cap does not fit over the cill

Verify that your cill is exactly 150mm wide; if the cill is too thick or has a reinforced profile, the cap may need slight modification or may be incompatible.

Pros and Cons

Pros

  • Provides a clean, professional exterior finish
  • Protects against moisture ingress at the cill ends
  • Durable and weather-resistant material
  • Easy to install for DIY projects

Cons

  • Limited to 150mm cill profiles
  • Requires proper adhesion to remain secure long-term
  • Not compatible with non-standard cill shapes

Setup, Compatibility & Care

To install, ensure the cut end of the window cill is clean, dry, and free from sawdust or grease. Use a high-quality PVC adhesive or superglue suitable for plastics to bond the cap to the cill surface for a permanent hold. Ensure the caps are firmly pressed against the profile until the adhesive sets. For maintenance, these caps require minimal care; simply wipe them down with a damp cloth and mild detergent during routine window cleaning to remove dirt and maintain their crisp, white finish.
