The 4 1/2″ frame provides more strength and durability than the more common 3 1/4″ frame other window manufacturers would offer.
This frame which is larger enables the thermal pane to be installed closer to the inside of the house allowing a higher thermal protection as well as a stronger window.
Instead of being built in modules with each section glued or screwed to another like most multi-paneled windows sold, our windows come in one solid frame. That makes it stronger and more durable. It also provides better protection against air and water leakage as well as more glass area and less frame.
