The colour of a camper van can have a significant impact on its internal temperature. Dark colours absorb more heat, which can make the van uncomfortably warm during hot sunny days. On the other hand, lighter colours like white or yellow reflect more sunlight, keeping the interior cooler. This is due to how different shades reflect or absorb sunlight—darker shades absorb a broader spectrum of light rays, while lighter shades reflect most of the sunlight rays.
The impact of a dark-coloured camper van depends on efforts to mitigate the effects, such as good insulation, window coverings, and proper ventilation. Additionally, the location of the van matters—parking in direct sunlight will result in a hotter interior compared to parking in the shade.

What You'll Learn
Dark colours absorb heat, making the camper van hotter in summer
Dark colours absorb heat, making a camper van hotter in summer. This is because darker shades, especially those close to black, absorb a broader spectrum of light rays, converting more of this light into heat. The darker surface will generally be warmer to the touch than a lighter one, even when both are exposed to the same amount of sunlight.
The colour of your camper does more than just give an aesthetic appeal. It can also affect how much summer heat is absorbed and retained. The result is more or less comfort and energy efficiency depending on the time of year. Dark colours absorb heat, making the camper van hotter in summer.
The science of heat absorption as it relates to colour is rooted in how different shades of colour will reflect or absorb sunlight. Each beam of sunlight contains ultraviolet (UV) rays, visible light, and infrared light. When these beams strike a surface, they either get reflected away or absorbed.
Dark colours absorb a broader spectrum of light rays, converting more of this light into heat. The darker surface will generally be warmer to the touch than a lighter one, even when both are exposed to the same amount of sunlight. This is why many vehicles are white. Dark colours are more susceptible to sun damage, and owners will see fading, oxidation, or even material degradation sooner than with light-coloured vehicles.
However, there are ways to mitigate the effects of a dark-coloured camper van. Good insulation, for example, will prevent heat from transferring to the interior. Proper ventilation can also help disperse accumulated heat, maintaining a more comfortable internal temperature.

Lighter colours reflect heat, keeping the van cooler in summer
This principle applies to vehicles, including camper vans. A black car, for instance, will be much hotter to the touch than a white car, even when both are exposed to the same amount of sunlight. In one experiment, a black car and a white car were left in the sun for an hour. The black car's interior temperature was 10 degrees higher than the white car. In another experiment, the skin temperature of a dark blue trailer was 20 degrees hotter than a white trailer.
The colour of a camper van will therefore have a significant impact on its internal temperature. A dark-coloured camper van will absorb more heat on its outer surface, and the inside living space will also grow uncomfortably warm during hot, sunny days. A light-coloured camper van, on the other hand, will reflect more sunlight and keep the internal temperature cooler.
The impact of a dark-coloured camper van on its interior temperature can be mitigated to some extent by efficient insulation, ventilation, and window coverings. However, the colour of a camper van will still make a notable difference to its internal temperature, and a light-coloured van will be far cooler in the summer months.

Dark colours can make a vehicle's interior 10-20°F hotter
Dark colours can indeed make a vehicle's interior hotter. The impact of a dark-coloured vehicle in the sun can be significant, with some sources claiming that dark colours can make a vehicle's interior 10-20°F hotter. One source claims that a dark-coloured vehicle can make the interior 20°F hotter after sitting in the sun for hours. Another source states that a black vehicle's interior was 17°F hotter than a white vehicle's interior after a few hours in the Georgia sun.
The science behind this is that darker shades absorb a broader spectrum of light rays, converting more of this light into heat. Lighter shades, on the other hand, reflect a bigger amount of the sun's rays, keeping the underlying surface cooler.
Therefore, if you are considering a dark-coloured camper van, it is important to plan carefully. You may want to limit your camping trips to winter or opt for camping destinations with cooler climates. Additionally, you will need to stay mindful of maintenance as dark colours are more susceptible to sun damage. It is also a good idea to carry auxiliary cooling systems, such as extra fans, reflective insulation, and heat-reflective blinds and curtains.
However, it is important to note that other factors also impact the temperature inside a camper van, such as insulation, windows, and ventilation. Proper insulation and ventilation can help keep the interior cool, while large or numerous windows can let in a lot of heat. Additionally, parking your camper van in direct sunlight will naturally make it hotter inside than if you park in the shade.

Dark colours can cause accelerated exterior sun damage
The colour of your camper van can have a significant impact on its exterior temperature and, consequently, its internal climate. Dark colours, such as black, absorb a broader spectrum of light rays, including ultraviolet (UV) rays, visible light, and infrared light. This results in higher temperatures on the surface of the van, which can lead to accelerated sun damage.
Multiple sources report that dark-coloured vehicles experience more rapid increases in temperature than their light-coloured counterparts. One individual compared the temperature inside their dark green car to that of their brother's white car, finding a difference of about 10 degrees. Similarly, another person compared the temperature of a light grey and a black motorcycle helmet, discovering a difference of up to 10 degrees. These differences in temperature can have a noticeable impact on comfort and energy efficiency.
The impact of dark colours on temperature is not limited to vehicles. A comparison between light grey and black roof shingles revealed that the black shingles were 20 degrees hotter. This finding underscores the role of colour in heat absorption and its potential consequences for structures.
The choice between a dark or light-coloured camper van extends beyond aesthetics. While dark colours can make a camper van stylish and stealthy for wild camping, they also contribute to higher external temperatures. This heat absorption can accelerate exterior sun damage, leading to issues such as fading, oxidation, and material degradation. Therefore, it is essential to consider the potential trade-offs when deciding on the colour of your camper van.

Insulation can help control the climate inside the van
Insulation is any material that prevents heat transfer, keeping the van cool in summer and warm in winter. It is one of the most important steps in a campervan conversion, dramatically affecting the internal temperature.
There are three types of heat transfer: radiation, conduction, and convection. Insulation materials are good at resisting heat flow, and their effectiveness is measured by their R-value. The higher the R-value, the greater the insulating power. Materials with lower K-values, or Lambda values, also allow less heat energy to pass through.
When insulating a campervan, it is important to consider the R-value and the thickness of the material. Some materials, like Polyisocyanurate (PIR) insulation board, have higher R-values per inch, meaning they provide greater insulation with less thickness. This is important in a van, where space is limited.
Other factors to consider when choosing insulation material include value for money, resistance to moisture, mould, and mildew, and non-toxicity. It is also important that the insulation can withstand vehicle motion and vibration.
There are several types of insulation that can be used in campervans, each with its own pros and cons:
- Reflective bubble foil is good at radiating heat but not so good at insulation. It should be installed with an air gap to be effective.
- Polyurethane spray foam has excellent thermal resistance but is expensive and requires careful installation to avoid health hazards.
- PIR insulation board is one of the most efficient insulation materials, with high R-values, and is easy to install. It is also non-toxic and environmentally friendly.
- XPS foam board is tough, moisture-resistant, and has a high R-value, but it is less environmentally friendly than PIR board.
- EPS foam board is similar to XPS but cheaper and less durable. It is also not as effective at preventing moisture ingress.
- Fibreglass wool is affordable, easy to install, and has good acoustic properties, but it has a low R-value and can deteriorate over time, releasing harmful particles.
- Rockwool has a higher R-value than fibreglass and is more durable, but it is more expensive and can also cause irritation.
- Sheep wool is a natural, sustainable, and non-toxic alternative, but it has a lower R-value than some other options.
When insulating a campervan, it is important to consider the entire vehicle, including the walls, ceiling, floor, windows, and doors. Different types of insulation may be more suitable for different areas. For example, XPS foam board can provide a solid and flat foundation for the floor, while reflective bubble foil can be effective for window coverings.
In addition to insulation, proper ventilation is key to controlling the climate inside the van. Electric vent fans can help expel warm air and draw in cool air, maintaining a comfortable temperature.
