While you can open up casement windows to the outside world, you can also count on our casement windows to fully seal the inside of your home from the elements outside when closed. These windows include a Weather-Tite compression seal and multipoint locking system to seal as tightly as possible. Our windows keep water and cold air out. 

Please call us today to install casement windows in your Hamburg, Orchard Park, or Lancaster, NY home.
