Q1: Are there any issues with the glass inside, such as steam or fogging?

Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all our doors and windows include frames, making wall installation hassle-free.
Q3: What if the glass breaks for no reason? I'm concerned the rest will shatter.'m afraid the rest will be broken
A: The glass would only break due to an impact force; it won't break on its own.'
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is recommended to use 5mm double glass because
a sliding door with single glass looks unattractive. The space for glass is wider, and using single glass would require excessive silicone filling.
Moreover, 5mm double glass is safer and provides better soundproofing than 6mm single glass.
Q5: Can you use rubber instead of glass silicone?
A: Yes, but only on one side. The other side must use glass silicone because rubber alone isn't strong enough and is prone to falling off.
