Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows come with frames, making wall installation straightforward.
Q3: What if the glass breaks without any apparent reason? I'm worried the rest might break as well.
The glass would only break due to an impact force, but it't break on its own.
Q4: Can I opt for 6mm single glass instead of 5mm double glass?
A: It is advisable to use 5mm double glass because:
A sliding door looks unappealing with single glass as it requires excessive silicon filling in the wide spaces.
5mm double glass is safer than 6mm single glass.
5mm double glass offers better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicone?
A: Yes, but it can only be used on one side. The other side must have glass silicone because double rubber is not strong enough and is more prone to falling off.
