Don’t Let Damp


Your Leisure Vehicle

During winter storage, damp and humidity is one of the biggest risks to caravans, motorhomes and boats. Causing mould, mildew, rot to timber framework and rust to metal parts, damp caused by temperature changes and humidity during the colder months of the year is a major risk to your leisure home.

But there is a solution, with BirchSorb, our market-leading moisture control solution specifically designed to eliminate damp and humidity.
