Vinyl windows is a desirable material for homeowners, builders and sub-contractors because of their outstanding thermal performance. Window Mart pays a lot of attention to energy-efficiency in vinyl windows. We use Low-E glass, warm-edge spacers and window frame with unique air multi-chamber system to improve energy-efficiency of our windows.
Unlike aluminum windows – which conducts heat rapidly – vinyl windows do a better job at reducing heat loss and maintaining a comfortable environment inside a house all year round.
The quality and energy-efficiency of vinyl windows can vary. It depends on various factors, such as manufacturing, glazing, frame material, insulation, and many others. Always look for the ENERGY STAR symbol to make sure that you’re getting energy-efficient windows. You can also compare key metrics, such as U-factor, solar heat gain coefficient (SHGC) and energy rating.
Professional installation is a major factor in determining the performance and ROI of the vinyl windows. If air is allowed to pass around the frame, then even the most energy-efficient and high-quality vinyl windows will lead to problems.
