Exterior UPVC Window Sill Accessories

 

Types of Exterior UPVC Window Sill Accessories

uPVC exterior window sills are popular due to their durability, low maintenance, and ease of installation. To enhance their functionality and aesthetic appeal, various accessories can be used in conjunction with these sills. Here are some common types of exterior uPVC window sill accessories:

  1. End Caps: These provide a neat finish to the exposed ends of the window sill. They protect the inner core of the sill from moisture and give a polished look to the installation.

  2. Joint Covers or Connectors: In cases where the sill extends beyond a single length and requires joining, these connectors or joint covers can seamlessly connect two pieces, ensuring a consistent appearance.

  3. Sill Nosing or Upstands: These are additional trims or lips that can be added to the back edge of the sill to ensure a neat finish against the window frame or to provide additional protection against water ingress.

  4. Sealants: Essential for preventing water ingress, sealants are used around the edges of the sill, especially where it meets the window frame and the facade of the building.

  5. Drip Grooves: While many uPVC sills come with pre-formed drip grooves, additional drip groove accessories can be attached if required, helping direct water away from the building.

  6. Fixing Clips or Brackets: These can be used to secure the window sill firmly in place, especially if there's a need for additional support or to prevent movement.

  7. Corner Pieces or Joint Trims: For window setups at the corner of a building, these specialized pieces ensure a snug fit and a neat appearance where two sills meet.

  8. Protective Films: Some uPVC sills come with a protective film that can be peeled off after installation. This film protects the sill from scratches or dirt during the installation process.

  9. Expansion Joint Covers: Due to temperature fluctuations, materials can expand and contract. Expansion joint covers are used to bridge gaps intentionally left to accommodate this movement, ensuring that the aesthetics are not compromised.

  10. Fixing Screws and Plugs: These are essential for affixing the sill to the underlying structure. The screws are often made of corrosion-resistant materials, and the plugs ensure a snug fit in the drilled holes.

When selecting accessories for a uPVC exterior window sill, it's essential to ensure compatibility with the specific sill brand or type. Using components designed for the same system or range ensures a good fit, consistent appearance, and optimal functionality.

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work”
