Insufficient ventilation can lead to elevated levels of moisture levels within the unguarded flooring underside, dampness inside the home, along with other structural problems. Sub-floor is the crawl-space existing in-between the ground and lowest floor of the building. Exposing it to high levels of moisture levels promotes fungal decay together with possible attack by timber pests such as termites that thrive in moist and damp areas. Specialists in Sub Floor Ventilation in Sydney has now can come in and advise homeowners on proper installation of sub-floor ventilation systems.
Maintenance of Proper Sub-Floor Ventilation
Sub-floors generally remain drier if built and maintained according to several rules as follows:
Roof Drainage – All water emanating from the roof and gutters needs to be diverted. Drainage water from the roof should not be allowed to saturate the soils present around the house foundation. The gutter system requires routine cleaning and maintenance to ensure it works properly.
Yard Drainage – The soils surrounding a house need to be sloped in a way that diverts water away from it.
Tree limbs overhanging the roof and gutters make their maintenance and cleaning a more challenging matter and could contribute to drainage problems in a great way.
When constructing a new house, it is critical to seal the exterior part of its foundation with care. In addition, one needs to install a house perimeter drain system of high quality. It is commendable as well that one puts in place separate drainage for gutters and downpipes. Professionals in Sub Floor Ventilation Sydney has now are capable of helping out homeowners to attain this goal.
The entire sub-floor area needs to accord ample ventilation to avert possible deterioration of timber floor construction. Moisture originating from the ground should be kept from occasioning unnecessary dampness or contributing to deterioration of building elements. The Building Code of Australia (BCA), in its second volume, stipulates that minimum clearance in-between the lowest frame of a building and its ground surface should not fall below 150mm. In addition, such clearance should comply with any requirements prescribed by the manufacturers of the flooring-materials.
Precautions for Effective Sub-Floor Ventilation
Sub-floors stay drier if one observes a couple of precautions as indicated below:
Storage – Most subfloors or crawl spaces are too small to be used for meaningful storage. Moreover, storing materials and stuff in there oftentimes act as a contributing factor to vital reduction of the required air circulation. This might create an atmosphere conducive for infestation by rodents and other pests.
Head room – Crawl spaces of larger nature have a tendency of keeping drier. As well, they end up allowing circulation of more air, apart from easing up repair and maintenance work.
Venting – The benefits of venting crawl spaces within a building remain debatable. However, most building codes advocate for a certain form of crawl space vents. A study whose results got published on the 1998 Building and Environment Journal demonstrated that the concentration of air strongly depends upon velocity of wind velocity within a given space. The study peered into impacts of subfloor ventilation along with protective measures that can be conducted against toxic soil vapors.
All sub-floors and crawl spaces should ideally be viewed as having potential problems of water and moisture.
