The 20ft 2 bedrooms 1 bathroom expandable container house is our most popular entry-level residential model. Many overseas families pick this unit for its moderate footprint, complete functional zones, and outstanding waterproof & insulation performance. Unlike low-cost generic expandable houses with thin panels and leak-prone seams, every detail of this model is optimized through systematic engineering design at TYGB Factory.

Water leakage is the biggest hidden trouble for prefab houses, so waterproof processing is the top priority of our engineering service. The technical team of TYGB Factory adopts multi-layer waterproof construction for roof, wall joints, floor and bathroom area. We lay integrated waterproof coils on the roof slope, add sealed rubber strips on all expandable splicing gaps, and do special anti-seepage coating for the bathroom wet zone.This layered waterproof system avoids rain seepage in rainy coastal areas and melting water leakage in snowy cold regions. Our engineers adjust waterproof thickness and sealing standards according to local annual rainfall, eliminating hidden water leakage risks fundamentally.

High-Density Thermal Insulation for Constant Indoor Temperature

Matching the waterproof system, thickened thermal insulation is another core engineering highlight of this 2-bedroom model. TYGB Factory fills wall, roof and floor cavities with high-density fireproof insulation boards, which effectively block outdoor extreme heat and bitter cold. The multi-layer hollow thermal insulation windows further reduce indoor and outdoor heat exchange, cutting energy consumption of heating and cooling equipment.Whether placed in high-temperature tropical zones or freezing northern areas, the stable insulation structure keeps indoor temperature comfortable all year round. Our engineering team can also upgrade extra thick insulation layers for customers located in severe cold regions, fully adapting to local climate conditions.
