How to Improve Insulation in Your Caravan or Motorhome for Cosier Travels

Better comfort, all year round

Whether you’re chasing summer sun or braving chilly nights on the road, good insulation is the key to comfortable travel in your caravan or motorhome. It’s not just about keeping warm in winter—proper insulation also helps keep interiors cooler during hot days and improves energy efficiency.

If your van feels too cold, too hot, or impossible to keep comfortable, it may be time for an upgrade.

Why Insulation Matters

In a caravan or motorhome, insulation plays a big role in regulating internal temperatures. Unlike traditional homes, these vehicles are often exposed to harsher conditions and have thinner walls, making them more vulnerable to heat and cold.

Without effective insulation, your heating or cooling systems must work harder, using more power and reducing battery life. It can also lead to condensation build-up, which encourages mould, dampness, and damage to your interior.

Whether you’re retrofitting an older model or improving a new one, there are practical ways to boost your insulation and create a more enjoyable living space.

Upgrade Window Coverings

Windows are one of the biggest sources of heat loss and gain. Using thermal blinds or insulated window covers can make a noticeable difference in keeping temperatures stable. Block-out curtains or reflective sunshades are also useful for reflecting heat away during the day and keeping warmth in overnight.

If you’re planning a longer trip, consider double-glazed window upgrades for even better thermal performance.

Seal the Gaps

Small drafts can make your van feel colder than it should. Common leak points include door seals, pop-top joins, floor corners, and skylights. Using rubber seals, weather stripping, or expanding foam in these areas can reduce air leaks and improve insulation immediately.

Don’t forget to check under seats, around wheel arches, and under cabinetry—these spots are often overlooked but can be major sources of cold air entry.

Walls and Ceilings

For those doing a more hands-on renovation or build, adding insulation behind the walls and in the roof cavity can dramatically improve thermal control. Rigid foam boards, foil-backed insulation, or lightweight batts are common choices.

Reflective insulation is particularly useful for reflecting radiant heat in warmer climates, while thicker materials help retain warmth in colder areas.

If pulling apart walls isn’t an option, insulated wall panels or stick-on thermal linings can be applied over existing surfaces as a more accessible upgrade.

Use Insulated Floor Mats or Carpets

The floor is often the coldest surface in a caravan or motorhome. Adding thick floor mats, carpets, or underlay can help trap heat and prevent cold from seeping up into your living space. Rubber flooring with an insulation layer is another good option if you’re renovating.

Ventilate Without Losing Heat

While sealing gaps is important, maintaining airflow is also essential to reduce condensation. Installing roof vents with built-in insulation or fans that help circulate air without letting heat escape is a smart way to balance warmth and ventilation.
