When selecting a quality window, it is important to consider the number of hollow chambers, (or cavities) that a window contains.Why is a multiple chambered window a sign of quality and integrity?

A window that incorporates a multi-chambered system increases the total weld surface that is available at each corner of the window. The larger the weld surface, the stronger the corners, and hence the increase in the integrity of the total window fit.

Other benefits of a multi-chambered system include:

• less distortion in frame and sash materials
• increased useable living space in your home
• reduced noise levels from outside your home and the
• provision for steel reinforcing when necessary
