Unlike traditional sliding doors, which limit you to opening only half the space, our folding doors provide a full, expansive opening, seamlessly connecting your indoor space with the great outdoors. The innovative bifold design features two or more interconnected panels that fold away concertina style, laying flat against one side for a clean, unobstructed view. These folding patio doors are the ultimate choice for maximizing natural light and creating sweeping, uninterrupted vistas of your garden or yard.

Q1: Are there any problems with the glass inside? Does it have steam or go foggy?
A: Usually, we use 5mm+12A+5mm double glass. Rest assured, our double glass is manufactured professionally to prevent steam or fogging between thepanels.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows include frames. Installing them on walls is perfectly fine.
Q3: What if the glass breaks for no reason? I'm afraid the rest will also break.
The glass will only break due to impact force. It won't break on its own.
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 looks less appealing with single glass. The wide space for single glass requires excessive silicon filling.
5mm double glass is safer than 6mm single glass.
5mm double glass offers 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 have glass silicon, as double rubber is not strong enough and is more prone to falling off.
