Attempting to lower the relative humidity within the space by heating the air is not an option due to Part L Building Regulations. In any event, heating would not be an option during the warmer months when moisture levels are much higher. 

Well sealed structures however can highly benefit from the use of desiccant dehumidification systems. Our systems will maintain the ideal relative humidity against prevailing weather conditions in your space all year round.

Products in storage such as wood, paper and cardboard will rapidly degrade above 55%RH. Unless treated steel products will usually corrode above 45%RH.
