Q1: Are there any issues with the glass inside? For instance, does it develop steam or become foggy?

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 straightforward and hassle-free.
Q3: If the glass breaks without any apparent reason, should I be concerned about the other panes breaking?'m afraid the rest will be broken
The glass would only break due to an impact force. It won't break spontaneously.'t break itself.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is recommended to use 5mm double glass because:
Sliding doors look unattractive with single glass. The wide space required for single glass would need excessive silicon filling.
5mm double glass offers enhanced safety compared to 6mm single glass.
5mm double glass provides superior soundproofing over 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 be glass silicon as double rubber lacks sufficient strength and is more prone to falling off.
