In order to ventilate more successfully, putting in sub ground followers will allow you to extract moisture and damp/stale air from the sub ground space and replace it with contemporary air drawn from the skin by a number of sub flooring fans. The purpose of sub flooring air flow is to replace the moist air with fresh dryer air. How much air flow is required will depend on the building and the specific location.

The minimal space for this free air space could be seen in determine three. There should be a minimum distance of 75mm to the dpc and 150mm to the underside of the timber joists. Ventilation in floors, especially suspended timber flooring is very important so as not to facilitate the build up of moisture inside the flooring structure.

If there’s no present power point (usually the case for sub floor techniques) an electrician can install the fan and anybody with a little bit of DIY know-how can do the remaining. For sub floor ventilation, we suggest aiming for between 6 and 10 air modifications an hour, nevertheless it is dependent upon the severity of the issue.

Ventilation could be improved by both passive or active air flow. Passive air flow utilises vents placed in the exterior wall of buildings. This can also require making openings in internal subfloor partitions to make sure that a crossflow of air is achieved. Active air flow entails becoming electrically powered followers and ducts that can be used to both push air into or, suck air from, a subfloor. These can then be connected to a timer so the hours of operation could be managed.
