Sub Floor Ventilation Kits

Importance Of Under Floor Ventilation

Some buildings have very little subfloor ventilation. Inadequate underfloor ventilation can lead to an accumulation of moisture in the sub floor meaning mould, rotting and structural weakness. This in turn can cause structural and health problems for the home and it’s occupants. The most common reason for inadequate under floor ventilation is that there are not enough vents, or they are too small for the size and layout of building. Building extensions, building location and soil type can all contribute to problems in the subfloor.

exhaust fan calculatorHow do I calculate which exhaust fan I need?

Fan suitability is usually determined by your room size and application. Generally we recommend aiming to achieve 15 air changes per hour for a bathroom, maybe 10 for a toilet. This is easily calculated, simply work out the size of your room in m3 (length x width x height in meters). You can then multiply this figure by 15 to give you an approximate capacity rating required for the fan. For your convenience all fans are measured in m3/hr. Please note 15 is our general recommendation, rooms prone to condensation may require 20-30 air changes.
