Living the vanlife is an exciting adventure, but dealing with cold weather requires preparation and smart strategies. Staying warm is crucial for comfort and safety. Here are essential tips for van dwellers on keeping the chill out.

Insulation is Key

The most important step in combating the cold is proper insulation. Think of your van as a thermos—you want to keep the heat in and the cold out.

• Insulate Walls, Floor, and Ceiling: Use high-quality insulation materials like polyiso foam board, rockwool, or even sheep's wool. Ensure there are no gaps for thermal bridging (direct contact between the van's metal frame and the interior).
• Insulated Window Covers: Windows are major heat sinks. Custom-made, multi-layered window covers (often utilizing reflective material like Reflectix sandwiched between fabric) are a game-changer.
• Address the Cab: The van's front cab area is poorly insulated. Use a heavy curtain or thermal barrier to separate the cab from the living space at night.

Heating Options

A good heater can transform your cold van into a cozy cabin.

Heater Type	Fuel/Power	Pros	Cons
Diesel/Gas Heater	Vehicle fuel tank	Very efficient, dry heat, reliable	High initial cost, professional installation recommended
Propane Heater	Propane tank	Good heat output, portable	Requires ventilation (creates moisture), needs fuel refills
Electric Heater	Shore power/battery	Quiet, easy to use	High power draw, only useful with external power source

If you plan to install a heater, ensure you follow all safety guidelines.

Ventilation and Moisture Control

It seems counterintuitive, but you need to ventilate even in the cold. When you breathe, cook, or dry clothes inside, you create moisture, and moist air feels much colder than dry air.

• Rooftop Fan: A quality fan is essential for regulating temperature and removing moisture. 
• Crack a Window: Even a small crack in a window is necessary, especially if using an unvented propane heater. This promotes air exchange and reduces condensation.
• Dehumidifier: For serious moisture issues, a small 12V dehumidifier or chemical moisture absorbers can help dry the air.

Personal Comfort

Layering isn't just for fashion; it's vital for staying warm in a small space.

• Warm Bedding: Invest in a high R-value sleeping pad and a winter-rated sleeping bag or a thick, down comforter.
• Wear Layers: Thermal underwear, wool socks, and hats are must-haves, even when inside the van.
• Hot Water Bottle: A simple, non-electric way to warm up your bed before climbing in.
