Q1: Are there any issues with the glass inside, such as it having steam or becoming foggy?
A: Typically, we use 5mm+12A + 5mm double glass. Rest assured, our double glass is crafted professionally, ensuring no steam or fogging issues between the double glass.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows include frames. Installing them on the wall is perfectly fine.
Q3: What if the glass breaks without any apparent reason? I'm worried the rest might also break.'m afraid the rest will be broken
The glass would only break due to an impact force; it won't break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is advisable to use 5mm double glass because
a sliding door looks unattractive with single glass. There is a wide space for glass, and if you use single glass, we would need to fill it with a significant amount of silicon.
5mm double glass is safer and more secure than 6mm single glass.
5mm double glass provides better soundproofing compared to single glass.
Q5: Can rubber be used instead of glass silicon?
A: Yes, but it can only be used on one side. The other side must still use glass silicon. Double rubber is not strong enough and is more prone to falling off compared to glass silicon.
