The Atrium 8700 series window and Atrium 8900 series window are both product lines offered by Atrium Windows and Doors, but there are several differences between the two:
1. Design and Style: The Atrium 8700 series window tends to have a more traditional design, while the Atrium 8900 series window offers a more contemporary and modern style.
2. Frame Material: The Atrium 8700 series window is made of vinyl, which provides good insulation and durability. The Atrium 8900 series window, on the other hand, typically features a combination of Exclusive InsulKor™ polyurethane fiberglass and vinyl, offering enhanced strength and stability.
3. Energy Efficiency: Both series offer energy-efficient options, but the Atrium 8900 series window generally has more advanced energy-saving features, such as Low-E glass and multiple panes for better insulation.
4. Customization Options: The Atrium 8900 series window often provides more customization options, allowing for a higher level of personalization with various grid patterns, hardware finishes, and glass options.
5. Price: Due to the differences in design, materials, and features, the Atrium 8900 series windows are typically priced higher than the Atrium 8700 series windows.
