What is a Multi-Chambered Vinyl frame?
Multi-chambered refers to the honeycombing or air spaces within a window frame. As a general rule, the more air spaces a frame has, the more efficient and stronger it is. All vinyl windows are multi-chambered, however, the more chambers a frame contains has a significant impact on its strength and efficiency. While most companies focus on the efficiency of the glass, it is important to also consider the efficiency of the frame.
