Q1: Are there any issues with the glass inside? Does it steam up or get foggy?
A: Usually, we use 5mm+12A+5mm double glass. Rest assured, our double glass is professionally manufactured, ensuring no steam or fogging between the double glass
Q2: Do all these doors and windows come with frames to mount on walls?
A: Yes, all the doors and windows include frames. Mounting them on walls is perfectly fine.
Q3: What if the glass breaks for no reason? I'm worried the rest will break too.'m afraid the rest will be broken
The glass would break only due to impact force, but it won't break by 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 glass requires a lot of silicone if single glass is used.
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 silicone?
A: Yes, but only on one side. The other side must be glass silicone because double rubber isn't strong enough and is more prone to falling off.
