Do Caravan Covers Cause Damp?

Looking after your caravan or motorhome properly will help to ensure that you do not have to pay for unnecessary repairs, and you will keep it in the best possible condition for longer, ready for decades of travel adventures.

The bad weather in winter causes numerous problems for vehicles, both internally and externally, which is why careful storage is required. When you put your caravan or motorhome into storage out of season, the best way to keep it protected is to use a cover, to shelter it from wind, rain, snow and hail.

However, some covers can cause problems such as external damp, so you should consider this when you are buying your cover. Plastic covers will cause external damp on caravans and motorhomes, which is a big concern that can be very costly to fix, so you should avoid using covers that are made from hard plastic.

How do plastic covers cause damp?

When using hard plastic covers, when it rains or snows, the water sits on top of the cover causing the vehicle to ‘sweat’ which creates external damp to the vehicle. As the water is not able to naturally pass through the cover, the water will gather on top of it and that moisture can quickly turn into a damp problem. So, while these types of covers provide a waterproof cover to stop water from getting in, when there is sitting water on the roof, your vehicle is likely to be getting damaged by ‘sweating’.

Plastic covers are also renowned for causing scratches to paintwork because they are made from hard plastic that can cause abrasions when pulling over the paintwork. So, if you want to protect your caravan from the elements but avoid the hazards associated with using plastic covers, there is another option.

Caravanners and motorhomers have faced the challenges of using plastic covers for years, which is why Pro-Tec knew a solution was required to prevent these problems. Pro-Tec is a company set up by caravan owners to put this long-time problem in the past.

The PROTEX003 fabric is exclusive to Pro-Tec and it is a 3-ply material that has a breathable membrane layer, which allows 1-metre of standing water but due to the breathable membrane, water can naturally pass through, avoiding the ‘sweating’ situation which causes external damp.
