Do window PE sunshades need to be slightly larger than the window frame?

It is generally recommended to install window PE sunshades slightly larger than the window frame size, in order to achieve better shading effect and visual aesthetics. The specific reasons are as follows:

■Enhance shading effect:
A sunshade slightly larger than the window frame can effectively cover the gaps at the edges of the window, prevent sunlight from leaking in from all sides, and improve the overall sunshade performance, especially when the side light is strong in the morning or dusk.

■Enhance privacy protection:
Large size sunshades can fully cover windows, avoiding gaps on the sides or up and down from being peeped by people, and better protecting the privacy of residents.

■Visual coordination is more aesthetically pleasing:
The sunshade is slightly larger than the window frame, which can create a more complete visual wrapping and make the space look more organized and unified, especially suitable for modern minimalist or neat style interior design.

■Adapt to slightly irregular window frames:
Some window edges may not be completely straight or have small errors, and a slightly larger size can serve to accommodate and avoid uneven or exposed sunshades and window frames.

■Prevent curling or wind leakage:
Larger sunshades are less likely to leak light from the edges when exposed to wind or slightly moved, improving their stability of use.

■Differences in adaptation and installation methods:
Different installation methods (such as exterior, interior, and ceiling) have different size requirements. If exterior installation is used (with the curtain installed outside the window frame), the sunshade usually needs to be 5-10 centimeters wider than the window frame to achieve the desired shading effect.
