First question: which version did you order?

How a home copes with frost depends mainly on the insulation chosen at order. At MP Modular the standard is EPS 50 mm sandwich panels — a seasonal version. For winter use we quote thicker insulation, PU/PIR panels, rock wool or a winter package.

Scenario 1: home not used in winter

Drain the plumbing, water heater and traps; leave valves open.
Protect frost-sensitive appliances.
Keep ventilation — open trickle vents to avoid damp.
Clear heavy snow from the roof and terrace.
Check the home after cold spells or install a temperature and humidity sensor with phone alerts.

Scenario 2: home heated all winter

Winter-grade insulation — heating can't make up for thin walls.
Heat source — usually an air conditioner with heating mode or an air-to-air heat pump; keep a backup for severe frost.
Pipes — insulate the water connection between ground and home and use trace heating; shield the space under the home from wind.
Ventilation — continuous air exchange prevents condensation.
Minimum temperature — keep a few degrees above zero even when away.

Roof

38 m² and 74 m² homes have a pitched roof as standard. Roof load capacity for your snow zone is confirmed in the quote for your location. With a flat roof, leaks are not covered by the manufacturer's warranty.

Checklist before the first winter

I know which insulation my home has.
Pipes and water connection are insulated; the space under the home is shielded.
I've decided: heat all season or drain and winterise.
Ventilation works.
I have a sensor or someone to check the home after frost.
