Yes! For cold climates, units include high-performance insulation: closed-cell foam (R-value 6–8 per inch) in walls, ceilings, and floors, plus double-glazed windows with low-E coatings. Some models add thermal breaks in steel frames to prevent heat loss. In sub-zero temperatures (-20°F/-29°C), indoor temps stay comfortable with a small heater or mini-split system. Snow loads are also handled—roofs support 30–50 lbs per sq ft (meeting International Building Code standards). For extreme cold (e.g., Canada, Scandinavia), upgrade to spray foam insulation and underfloor heating for year-round livability.
