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 walls is perfectly fine.
Q3: If the glass breaks without reason, should I worry about the rest?'m afraid the rest will be broken
The glass would only break due to a significant 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:
Sliding doors look unattractive with single glass as there is a wide space for glass. If you use single glass, we will need to fill it with excessive silicon.
5mm double glass is safer than 6mm single glass.
5mm double glass is more soundproof than single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but it can only be on one side. The other side must use glass silicon because double rubber is not strong enough and is more prone to falling off compared to glass silicon.
