Frequently Asked Questions (FAQ)
Q1: What makes this sliding door thermal break effective for energy savings?
A1: The PA66 nylon insulation strip is integrated into the aluminum profile, creating a thermal barrier that significantly reduces heat conduction between interior and exterior. This minimizes energy loss, keeping your space cooler in summer and warmer in winter, leading to lower heating and cooling costs.
Q2: Can you customize the glass thickness or type for this door system?
A2: Yes, as a manufacturer, we offer flexibility. The standard is 5+20A+5 (30mm) double tempered glass, but we can accommodate an optional 35mm thickness. For specialized requirements like laminated or low-E glass, please contact us for custom solutions.
Q3: How does the double track system improve functionality compared to single track doors?
A3: The double track design allows for two sliding panels to operate independently on separate tracks, offering a wider opening area and more versatile configuration options. This is ideal for large openings, providing better ventilation and a seamless indoor-outdoor transition without compromising on structural integrity or thermal performance.
