Buying Guide
What to consider when choosing a cornice box or valance panel:
- Coverage and size: Match the product length to your window width. For very wide windows, consider longer panels or multiple sections.
- Mounting style: Wall or ceiling mounting options affect installation and durability. Ensure your wall structure can support the unit.
- Material and finish: Aluminum alloy offers durability and a clean look. A white finish blends with neutral decors, while black options pair with modern aesthetics.
- Blackout performance: If you need darkness, verify that the pelmet covers tracks and blocks light leaks effectively.
- Hardware and installation: Look for included brackets, end caps, screws, and connectors. Power drill installation is common, but access to tools matters.
- Maintenance: Smooth, non-porous surfaces are easier to clean and resist staining over time.
- Flexibility for existing hardware: Some products are designed to fit without removing current curtain rods, which can simplify upgrades.
How to measure for a cornice box
Measure the window width, then choose a cornice box that fully covers the glass with some overhang on each side. For a seamless look, aim for less than 2 inches of visible track beyond the box edges. If you have ornate frames or corner walls, plan for consistent alignment across multiple sections.
Installation tips
- Mark stud locations or use appropriate wall anchors for secure mounting.
- Use a level during installation to ensure a straight, even finish.
- Follow the hardware kit instructions for bracket spacing and end-cap placement.
- Test the system after mounting to confirm stability before hanging curtains.
Maintenance and care
- Wipe with a soft, damp cloth to remove dust and fingerprints.
- Avoid abrasive cleaners that could scratch the surface.
- Check screws and brackets periodically to maintain secure installation.
