A few practical questions usually tell you more than a long product pitch:

• Is the glass package low-E and filled with insulating gas?
• Does the frame design reduce air leakage at the sash and corners?
• Are the performance numbers suited to a climate that needs both winter and summer protection?
• Will the window fit the home’s style and local requirements?
