At an air velocity of 5m/s, the air move is 200m3/h for the 204x60mm measurement duct and 100m3/h for the 110x54m duct measurement. When the air velocity is lowered to three.5m/s, the air move for the final ducts rises to 150m3/h and 75m3/h respectively. These specifications are probably the most generally used for residential air flow. When gluing the ducts together, the system is fully sealed.
Ventilation could be improved by either passive or active ventilation. Passive air flow utilises vents positioned in the external wall of buildings. This may require making openings in inside subfloor partitions to make sure that a crossflow of air is achieved. Active ventilation entails fitting electrically powered followers and ducts that can be utilized to either push air into or, suck air from, a subfloor. These can then be attached to a timer so the hours of operation could be controlled.
