How to Prevent Damp Sub-floors with Sub Floor Ventilation

The most efficient way to ventilate the sub floor area is to replace the moist air with fresh, dry air. The Solar Whiz Sub-Floor Extractor Fans ensure an efficient, cost effective and sustainable under floor ventilation solution without any running costs.

The main benefit of using solar powered fans for under floor ventilation is that the fan only runs when the sun is out. This means that the majority of the replacement air coming into the sub-floor will have a relatively low moisture content. This makes solar sub floor ventilation far more effective than timer operated extractor fans which may increase humidity under the floor by introducing air with high moisture content during wet weather. states that under floor ventilation “minimises sub floor moisture which helps to prevent timber decay and creates an environment that discourages termite attacks” This sub floor ventilation requirements page can help you decide what kind of subfloor ventilation would suit your area and home.

Sub Floor Ventilation – The Best Place To Start
