Side and sill channels are essential for achieving maximum light control and eliminating edge light gaps. To ensure these components blend perfectly with your window mullions or interior trim, Soleffect offers our light-blocking hardware in five distinct architectural finishes.
Standard Finish Options
Our side and sill channels are extruded from high-quality aluminum and finished to withstand daily operation while maintaining a premium aesthetic. The following colors are available for all standard channel profiles:
- White: A bright, clean finish that matches most standard commercial window pockets and residential trim.
- Black: A deep, matte-style finish perfect for high-contrast designs or theater-style blackout requirements.
- Bronze: A rich, dark architectural tone commonly used in high-end office and hospitality projects.
- Alabaster: A warm, off-white selection that bridges the gap between white and beige for softer interior palettes.
- Anodized: A clear, satin-metallic finish designed to match natural aluminum storefronts and curtain wall systems.
Complete Light Blockage
When paired with our blackout fabrics, these color-matched channels provide a comprehensive light-seal solution. By matching the channel color to your window frame, the hardware becomes a permanent, unobtrusive part of the architectural envelope.
