What is a recommended gap for effective moisture management in construction?

The recommended gap of 10mm for effective moisture management in construction is based on industry standards aimed at preventing moisture accumulation, which can lead to serious issues such as mold growth, wood rot, and degradation of building materials. This gap provides an adequate space for ventilation, allowing air to circulate and moisture to evaporate, particularly in areas where materials are susceptible to absorbing water, such as in walls or between roofing systems.

A gap that is too small may not facilitate sufficient airflow and moisture dissipation, while a gap that is too large could compromise structural integrity and insulation effectiveness. The 10mm gap strikes a balance, ensuring that moisture can escape while still maintaining adequate barrier protection. This standard is supported by best practices in building science, which emphasize the importance of ventilation and moisture control in maintaining the longevity and safety of a building.
