Ventilation can be incorporated in various ways; at eaves, with over fascia vents, or soffit vents, ridge and within the roof covering via in-line tile or slate ventilators.
Ventilating felt can also be used to assist air-flow through the roof space and in some cases provides adequate air flow without the need for additional provision at ridge and eaves.
The basic requirements for ventilating a traditional cold loft space are that air should enter the roof void at the lowest point on one side of the roof and exit on the opposite side of the roof and / or ridge. Water vapour rises up through quilt or fibrous insulation, and meets the air in the loft, where some of the moisture is absorbed – the quantity depends on the air temperature.
