Designed with a lower pulley featuring ball bearings and a stainless steel slide rail, our doors effectively prevent wind, dust, and rainwater from seeping into the room.

Engineered to prevent accidental hand pinching.

Unlike conventional sliding doors that restrict your view by only allowing half the area to be opened, our folding doors revolutionize your space with their ability to fully open, creating expansive, panoramic vistas of your garden or yard. Seamlessly blending the interior with the exterior, bifold doors are composed of two or more interconnected panels that fold away neatly to one side in a concertina manner. These folding patio doors are the optimal solution for maximizing natural light and providing the most extensive, uninterrupted views. At ZIIISUN, we offer an extensive selection of RAL color options, diverse finishes, various frame styles, and customizable sizes, allowing you to tailor a bespoke solution perfectly suited to your project.

Q1: Are there any issues with the glass, such as steam or fogging?
A: Generally, we use 5mm+12A+5mm double glass. Rest assured, our double glass is crafted professionally to prevent steam or fogging between the doubleble glass.
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 happens if the glass breaks without any apparent reason? I'm concerned the rest might break too.
A: The glass will only break if subjected to impact force; it won't break by itself.'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 less attractive with single glass. The space for glass is wider, requiring excessive silicon if single glass is used.
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 use glass silicon because double rubber isn't strong enough and is more likely to fall off.
