Furniture
Moisture in the air can cause damage to furniture as the
wood expands or contracts with an increase or decrease
in the relative humidity. A relative humidity of between
40% -60% is tolerable. If values are maintained outside
this range for a sustained period damage to the furniture
may occur.
To prevent damage, assure relative humidity
of air is not too high.
The damages can be visible if the relative humidity is
higher than 80% for a long time. To prevent damage,
ventilate the van, using dehumidiers or water adsorbent
substances.
When wood is wet, wipe it dry. Do not just wait for the
sun to dry it. The longer the water stays on the surface,
the more damage it can do.
Defects caused by swelling, bowing, twisting or
delaminating generated by high temperature or high
relative humidity of air) will not be accepted as warranty
Humidity
Air contains moisture – this is called humidity. The
higher the temperature of the air the more water it is
able to hold. Air at 20°C can hold a lot more moisture
than air at 10°C. The term ‘relative humidity’ describes
how much moisture air contains at a given temperature.
100% relative humidity means the air is holding as much
moisture as it can at that temperature.
The more humid the air is in your caravan, the more
energy it takes to warm your van because it is also
warming the water in the air. This means it will be more
expensive to heat!
A good range of indoor humidity for comfort and health
is between 30-60% during cooler months of the year.
Mould is likely to occur if the relative humidity indoors is
70% or more for long periods of time. Keeping humidity
levels under 50% also helps to minimise or control dust
mites.
About Condensation
When the humidity is high inside a van and it is cold
outside the water vapour condenses on cold surfaces.
What can causes dampness and condensation in your
van?
• Lack of adequate ventilation and/or heating.
• Water coming in from the outside through leakage,
seepage or open windows
• High levels of moisture/water vapour being produced
inside the caravan
Humid air and condensation can also be generated by
things people do on a daily basis.
• Cooking Up to 3 litres per day
• Showers and baths 1.5 litres per person
• Washing dishes Up to 1 litres per day
• Breathing, active adult 0.2 litres an hour per person
• Breathing, adult asleep 0.02 litres an hour per
person
