If the fireplace has been panelled over, it is completely crucial that the air inside the chimney breast can proceed to maneuver so that it does not turn out to be stagnant and trigger condensation after which damp. Where the outside floor stage is too high to carry air to the sub-ground void in a straight line, a telescopic underfloor vent must be connected to the back of the air brick to conduct and defend the airflow throughout up to 5 brick programs. In a cavity wall, the airbrick must be inserted into the outside leaf of the wall as for a stable wall, however you will want further long drill bits (300mm, 12in) to chop by way of the inside leaf of the wall as nicely and thereby keep the via move of air to the sub-ground void.

They can be used on a range of radon ranges, even over 1000 Bqm -three .


At an air velocity of 5m/s, the air circulate is 200m3/h for the 204x60mm size duct and 100m3/h for the 110x54m duct dimension. When the air velocity is reduced to 3.5m/s, the air flow for the final ducts rises to 150m3/h and 75m3/h respectively. These specs are probably the most commonly used for residential ventilation.
