Q1: Are there any issues with the glass inside, such as steam or fogging?
A: Typically, we use 5mm +12A + 5mm double glass. Rest assured, our double glass is professionally made, ensuring no steam or fogging occurs between the doubleglass.
Q2: Do all these doors and windows come with frames to mount on walls?
A: Yes, all the doors and windows include frames, making it easy to install them on walls.
Q3: The glass broke for no apparent reason. I'm concerned the rest will break too.’m
The glass would only break due to a significant impact force. It wouldn't break on its own.’t
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is better to use 5mm double glass because
a sliding door with single glass looks unattractive. If you use single glass, a wide space would be filled with excessive silicon.
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 be glass silicon, as double rubber isn't strong enough and is more prone to falling off compared to glass silicon.
