Double hung windows are windows where both sashes move up and down within the frame, while a single hung window features a top sash that is fixed in place, with the bottom sash operable. Both of these feature sealing rubber strips for better sealing capabilities.

We offer a variety of single and double hung window hardware made of zinc alloy, aluminum alloy and copper materials at an affordable price, as well as offer customization services and different surface treatments to ensure all customer needs are met.
