WEIKA Customized Interior Residential Vinyl Double Hung Window UPVC

☆Product Description

What's the difference between American UPVC double-hung windows and UPVC

sliding windows?

Opening method: American UPVC double-hung windows use a vertical opening up

and down, while UPVC sliding windows have a left and right sliding opening. Lift-and-pull

windows can provide a larger opening area, usually up to 1/2 or even more opening,

resulting in better ventilation and views. In contrast, sliding windows usually open no more

than half the area.

Ventilation: Because the opening height of a UPVC double-hung window can be designed

to be close to human height, ventilation and comfort are greatly enhanced. The ventilation

effect of sliding windows is limited by the opening area.

Security: American UPVC double-hung windows have a structure that is difficult to intrude

from the outside, and therefore excel in crime prevention.

Cleaning and Maintenance: Sliding windows are relatively easy to clean, but due to the

sliding of the window, dust may accumulate in the track and need to be cleaned regularly.

When choosing a window, the most appropriate type of window should be determined by

the specific living environment, security needs, aesthetic preferences and usage habits.
