Expandable container houses are designed with multiple layers of moisture protection to prevent water damage and ensure a dry interior. The steel frame is usually coated with anti-corrosive paint or galvanized to resist rust and corrosion from rain or humidity.
The walls and roof feature a vapor barrier that prevents moisture from seeping into the insulation and interior spaces. High-quality models also include weatherstripping around doors and windows to seal out rain and drafts. Some manufacturers offer additional upgrades like sloped roofs with gutters and downspouts to direct water away from the foundation, and raised floors to prevent flooding in low-lying areas. Regular maintenance, such as checking seals and draining gutters, will help maintain the home’s moisture resistance over time.
