Did you know that double hung sash windows (where you can open the top and also open the bottom half of the window) help you ventilate and cool rooms more effectively than other types of window?
If you have a double hung sash window then it means that you have more options than a normal type of window (which is either just open or shut!)
For example, if the upper sash is half open (partially down), and the lower sash is also half open (partially up) then the room will cool down much faster!
The cool air enters the room on the lower sash gap, and warm air exits the room via the upper sash gap.
On my site you can find the best sash window repair and maintenance guides, and a list of some of the sash window companies.
