Trades Training Radon
Radon control is all about the creation of constant depressurisation.
Plumbing ventilation is all about the relief of short term depressurisation.
Mechanical ventilation is all about the volume and throw of air flow.
These three disciplines do not seek the same objectives and do not work with the same principles, which results in significant differences in the techniques required for system installations. These differences are the reason for the creation of these videos in the Learning Curve series.
Radon control at its best has a total gas barrier isolating the sub-slab zone from the household air and creates its constant depressurisation with a very low volume of gas movement.
The climate difference between the US and Canada also affects radon control techniques; from the need for indoor gas tight fans in the north to the increased effectiveness of passive stacks in colder climates.
