About relative humidity and rising damp
Ideally, relative humidity sits between 40 and 60%. High-humidity homes — where humidity levels exceed 60% — are a recent phenomenon. In older homes, natural ventilation is more common, as they not as airtight and often have single glazing. During renovation work, however, crevices and gaps are sealed, and single glazing is replaced by double glazing. The most common result? Rising damp, making relative humidity levels increase dramatically.
Some rooms are more humid than others — think of bathrooms, kitchens and laundries. In high-humidity homes, however, you need to consider the humidity level in other rooms as well. So, what type of flooring to pick?
