The Off Cut Shades Chainless Blackout Roller Shade features 100% polyester fabric in an open roll design. The plain hem design features a sewn pocket with a weighted insert creating a beautiful and clean finish to the shades. The headrail is made from sturdy white aluminum increasing durability for heavy use applications. The fabric blocks 100% of light and is ideal for bedrooms or where limiting a glare is required. Even though the fabric blocks 100% of the light, there is some light seepage that occurs around the perimeter of the window. The fabric comes in great interior colour options to match your style and with a white exterior back. This white backing provides a consistent exterior look to your home and meets the strictest condo or apartment requirements.
