This is a key part of your camper design and if carried out correctly it will provide your camper with a comfortable living environment for you to enjoy year after year.
A stuffy van with condensate on windows and lingering cooking smells is not something that you would want in your house let alone in your prized campervan! Thus you must consider all the components of this subject very carefully and the result will be very much worthwhile.
Warmer air is able to hold onto more water vapour then cooler air. When warm air comes into contact with cooler air, or a cool surface then the air temperature drops and the vapour condenses and forms water droplets. Not good in any campervan
Reduces heat loss and keeps the interior of the camper cool when the temperature is hot outside
Removes excess water vapour (leading to condensation) and also removes pollutants, cooking odour and exhaled C02 from your campervan
A vapour barrier installed over the insulation is a good design feature to stop vapour-laden air seeping through interior panelling and onto cold metal surfaces where condensation is likely to form and possibly create rust or saturate insulation materials
Is the process whereby the colder outside temperature is conducted to the interior via an unbroken structure or component. A thermal break or other measures are required to prevent heat loss and cold spots
