Q1: Are there any issues with the glass inside? Does it get steamy or foggy?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is professionally crafted, ensuring no steam or fog between the double glass.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows include frames, making it easy to install them on walls.
Q3: What if the glass breaks for no reason? Will the rest follow?'m afraid the rest will be broken.
The glass would only break due to impact force, otherwise, 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 better to use 5mm double glass because
Sliding doors look unattractive with single glass. The wide space for the glass would require a lot of silicon if you opt for single glass.
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 isn't strong enough and is more prone to falling off compared to glass silicon.
