Here are some key factors to consider:
1. For energy-saving windows choose vinyl, wood or fiberglass insulation, preference for double/triple glass, Low-E coating, argon filling for better temperature control. Check the U value and SHGC rating, and consider the style of window or awning for better sealing.
2. Choose a window style that matches your home design, such as a sash in a traditional or minimalist modern aesthetic frame, and the color of the frame can be mixed or contrasted.
3.Choose materials that are not only visually appealing, but also durable and low maintenance. For example, aluminum frames are more resistant to weathering than wood, making them a wise choice for longevity.
