FAQs about YG expanding container homes
Q1: How to set up the kitchen, bathroom, water, and electrical pipes inside?
Answers: Water & electrical systems: Wires and pipes that meet international standards, including CE/SAA/UL, are pre-installed on the top and bottom frames during factory production. On-site assembly is as easy as plugging in a connector.
Kitchen & bathroom customization: You can choose integrated bathroom and full kitchen modules when placing orders. All sanitary ware and cabinets will be delivered together with the unit and assembled on site.
Q2: Will it be extremely hot in summer and freezing cold in winter? How about sound insulation?
Answers: Definitely not. It all depends on your choice of wall materials. The walls use Rockwool or PU sandwich panels.
Heat insulation: The sandwich panels deliver great thermal insulation. Paired with broken bridge aluminum doors and windows, it keeps warmth just as well as light steel villas.
Sound insulation: Rockwool naturally absorbs sound. It blocks most high-frequency noise from outside and ensures a comfortable living environment.
Q3: Will expanding container homes leak water after repeated folding and use?
Answers: No leaks will occur under normal use. When designing expandable prefab houses, we focused heavily on waterproofing for folding joints, relying on three key designs below:
Drainage structure system: The roof has a gentle slope, and hidden drainage channels are built inside the main beams. Rainwater flows down the slope into the channels and drains out through pipes inside four corner posts, leaving no standing water at joints.
Automotive-grade sealing strips: Flexible and anti-aging EPDM rubber strips (same as car door seals) are fitted at movable hinges and seams. The joints stay fully sealed even after hundreds of folding cycles.
Interlocking groove anti-leak design: Wall panels adopt male and female interlocking grooves. Rainwater only flows down along the exterior wall and cannot seep indoors across the grooves.
Q4: Can multiple flat pack container homes be connected or stacked?
Answers: Yes, absolutely. You can connect units side by side endlessly to enlarge living rooms or bedrooms, or stack them vertically. YG flat pack container homes can be safely stacked for 2 to 3 floors. They are ideal for combined apartments, office buildings, and layered homestays for tourism.
