Blackout material: Cellular blind is made of 0.55" single cell blackout honeycomb fabrics with aluminum foil, which can 100% block sunlight. All honeycomb fabrics have a white backing to reflect even more daylight and provides a uniform appearance from the outside. Both sides can be installed. Energy saving: Unique honeycomb construction offers sound absorption, while also reducing the harmful effects of ultraviolet rays and providing ideal insulation for energy efficiency. These cell shades feature air-trapping honeycomb cells that repel summer heat and winter cold alike for year-round comfort and style. Made to order: The blind is custom made. You can find the feasible size range in the "Customize Now" button on the top right. It's typically installed inside the skylight frame (minimum 2" depth required). Special L-shape bracket is also available for over-the-frame mounting. Please make sure the net size measurement as precise as possible. To avoid any installation interference, the size will be 0.1" smaller in both width and length. Package: Customer self-installs, all the mounting kits, instructions are included in the package.
