Tips to Mitigate Condensation:

  1. Maintain Good Ventilation: Ensure that the loft space is well-ventilated. Avoid blocking eaves and roof vents, and consider adding additional ventilation if necessary. This promotes airflow and helps prevent the buildup of moisture.
  2. Use Breathable Materials: When installing loft boarding, consider using breathable materials that allow air to circulate. This can help prevent the buildup of moisture between the boarding and insulation.
  3. Install Vapor Barriers: Consider installing vapour barriers between the loft boarding and insulation. Vapor barriers can help control the movement of moisture and prevent it from reaching cold surfaces.
  4. Check and Improve Insulation: Verify that your loft insulation is sufficient and properly installed. Upgrading insulation can enhance the thermal performance of the loft space, reducing the risk of condensation.
  5. Regular Maintenance: Conduct regular checks for any signs of condensation, water damage, or mould. Promptly address any issues to prevent them from escalating.


In conclusion, loft boarding itself does not cause condensation, but certain associated factors can contribute to moisture-related problems if not addressed. By ensuring proper ventilation, using breathable materials, installing vapour barriers, and maintaining adequate insulation, you can enjoy the benefits of loft boarding without compromising the overall moisture balance in your home. As with any home improvement project, careful planning and attention to key factors are essential to a successful outcome.
