Q1: Are there any issues with the glass inside, such as steam or fogging?
A: Typically, we use 5mm + 12mm + 5mm double glass.12Our double glass is crafted professionally, ensuring no steam or fogging occurs between the panes.
Q2: Do all these doors and windows come with frames for wall mounting?
A:Yes, all the doors and windows include frames, making wall installation straightforward.
Q3: What if the glass breaks without any apparent reason? I'm concerned the rest might break too.A: The glass will only break due to a substantial impact force; it won't break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is highly recommended to use 5mm double glass.
Using a single 6mm glass will make the sliding door look unappealing, as it requires a significant amount of silicon to fill the space. Moreover, 5mm double glass is safer and more soundproof.
Q5: Can you use rubber instead of silicon for glass?
A: Yes, but only on one side. The other side must use glass silicon. Double rubber isn't strong enough and is more prone to falling off compared to glass silicon.
