Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows come with frames and are ready for wall installation.
Q3: What if the glass breaks unexpectedly? I'm concerned about the rest breaking.'m afraid the rest will be broken
The glass only breaks due to an impact force. Rest assured, it won't break on its own.'t break itself.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is highly recommended to use 5mm double glass because
a sliding door with single glass looks unappealing. The wide space for single glass requires excessive silicon filling.
5mm double glass is safer than 6mm single glass.
5mm double glass provides better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but only on one side. The other side must use glass silicon because double rubber isn't strong enough and is more prone to falling off.
