Recommendations by NLA

1. Humidity
Generally, it is recommended that relative humidity remain at 50% with a maximum change of plus or minus 5% per month.
2. Temperature
Most moulds thrive at warmer temperatures. Temperatures below freezing will not kill mould, but they do make it dormant.
For patron comfort, temperatures of 21 Celsius plus or minus 2 are acceptable in libraries, provided relative humidity is kept at 50%
