The exterior wall system typically ranges from 120 mm to 200 mm in thickness. Due to the slim profile of the walls, light-gauge steel structures offer approximately 10%–15% more usable floor area than traditional homes, with interior usable space exceeding 90% of the total footprint; internal spaces can also be flexibly partitioned. Utility lines can be routed through pre-formed openings in wall, floor, and roof components, ensuring a neat, concealed appearance.
① Wall cavities are filled with glass fiber insulation, providing excellent thermal insulation and soundproofing performance;
② Breathable, waterproof membranes effectively regulate indoor humidity for greater living comfort while preventing mold growth within the walls;
③ Utility lines are concealed within the walls, saving interior space.
