Q1: Are there any issues with the glass inside your doors? For instance, do they develop steam or become foggy over time?
A: Typically, we use 5mm+12A+5mm double-glazed glass. Rest assured, our double-glazed glass is crafted with professional precision, ensuring no steam or fogging between the doubleglasspanes.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, indeed. All our doors and windows include frames, making installation on walls straightforward and hassle-free.
Q3: If one piece of glass breaks without any apparent reason, should I be concerned about the rest?A: Glass typically only breaks due to external impact. It won't break on its own without a cause.
Q4: Can I opt for 6mm single glass instead of 5mm double-glazed glass?
A: It's highly recommended to use 5mm double-glazed glass. Here's why:
Sliding doors look unappealing with single glass, which leaves a wide space needing excessive silicone.
5mm double-glazed glass offers superior safety over 6mm single glass.
5mm double-glazed glass provides better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicone?
A: While it's possible to use rubber on one side, the other side must be glass silicone. Double rubber lacks the strength and durability of glass silicone, making it more prone to falling off.
