Q1: Are there any issues with the glass inside? Is there a risk of it steaming up or becoming foggy?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is crafted with professional precision, ensuring no steam or fogging occurs between the doublepanels.
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 seamless and straightforward.
Q3: If the glass breaks without an apparent reason, should I be concerned about the rest?'m worried the others might break too.
A: The glass will only break if it incurs significant impact force. It will not break on its own.'
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is highly recommended to use 5mm double glass because:
1. Sliding doors look less appealing with single glass due to the wide space for glass, resulting in the need to fill it with excessive silicon.
2. 5mm double glass is safer than 6mm single glass.
3. 5mm double glass offers better soundproofing compared to 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 is not strong enough and is more prone to falling off.
