Buying Guide
What window type do you have? Inside or outside mounting affects shade sizing and coverage. Outside mounts typically require a shade wider than the window by about 4 inches to fully cover the frame. Inside mounts should account for any deduction in width to fit snugly within the window opening.
Which safety features matter? Cordless designs reduce risk for homes with children and pets. Look for a robust spring-loaded mechanism and a defined stopping system to ensure consistent operation.
How important is energy efficiency? A thermal backing and UV protection help maintain interior temperatures and protect furnishings. If you live in a hot or cold climate, prioritize shades with insulating properties.
What about installation and durability? No-tools or no-drill options are ideal for renters. If you own the home, a standard install with brackets may offer more permanent stability and ease of maintenance. Consider fabric type and ease of cleaning for long-term use.
