At Alcor, we understand that renovating or building your home can be difficult and full of time-consuming choices. With 60+ years in the business, we’ve come to understand what styles and options work best for our clients and we can answer any questions you might have. Since there are a huge variety of window styles available, we took the time to lay out the features and benefits of each style and define some standard industry terms. 

 


 

Industry Term: Sash 

A window “sash” is the unified framed part of the window that contains the glass, frame, gaskets and other hardware of the window. Many windows have more than one sash. 

Industry Term: Mullion

A mullion is a vertical or horizontal connecting unit between two or more windows, mulling is a way of connecting windows to allow light and to create visual interest.
