Why Wet Area Ventilation Is Beneficial For Your House

Copyright (c) 2015 Matt Reardon

Good house ventilation is always recommended for the health of your family and the house structure. However, it takes an even more critical significance when looked at from the perspective of wet areas in the house. A good example of a wet area in the house is the bathroom.

A good bathroom exhaust fan works to effectively reduce moisture, prevent mould, improve air quality, and protect house walls and fixtures. Other wet areas include the toilet and laundry rooms which, through constant use, may remain damp for most of the time. If not adequately taken care of, this could lead to serious health issues and complications for the entire family.

Good wet area ventilation helps you achieve a conducive indoor environment and its benefits include:

- Continuous Supply Of Fresh Air

A sufficient quantity of fresh air is needed to provide the required amount of oxygen, and control humidity and odours commonly found in wet areas. This is especially crucial during warmer periods of the year, particularly during the summer.

- Uniformly Distribute Air

Incoming fresh air is distributed to all areas using an exhaust fan, which reduces the risk of uncomfortable and unhealthy draft. A house with free flowing air is likely to be more comfortable and healthy, in accordance with the Australian Building Code on Home Ventilation and the Australian Standards (AS) 36662 on Home Dwellings and Ventilation.

- Regulate Room Temperature

Air temperatures above or below an acceptable temperature range will interfere with your ability to achieve and maintain a normal body temperature, as well as a good health status. Rapid and frequent temperature changes can cause drafty conditions, which may lead to stress and respiratory health issues.

- Exhausting Respired Moisture

Respiration is the main source of water vapour. In combination with other related factors, like evaporation derived from wet floors, your room is likely to get damp quite fast and attain temperature ranges that are uncomfortable. This can be easily and conveniently rectified by maintaining good and constant air exchange. Good ventilation aids in removing unwelcome odours, cutting down on the spread of disease-carrying organisms and decelerating building structure deterioration.

- Remove Gases And Odours

Carbon dioxide from respiration displaces vital oxygen. This may cause unpleasant conditions for those living in the house, posing serious health risks.

The HRV (Heat Recovery Ventilation) system would be a smart choice for your ventilation needs. It's a system that offers a perfect extractor-fan solution for wet areas. A good HRV exhaust systems would come with an advantageous warranty.

The best time to install a ventilation system is during construction. It's easier and more convenient to install the whole set as you are putting up your bathroom. Some of the key considerations when choosing your system are: size of the wet area to be ventilated, location of your building and your climatic zone.

It's important to engage professionals when installing the ventilation system. They are better placed to know what the national and local regulations require, such as the National Construction Code Series on Damp and Weatherproofing.
