Ventilation Systems

There are several kinds of ventilation systems on the market. The most popular systems that DampShield installs are the Brass Mesh Wire Sub-floor Vents, internal plaster/external terracotta louvre vents and the mechanical Ecofan. When the sub-floor and internal air flow is increased you are protecting your house from the growth of mould and mildew, timber decay, floor board cupping due to varying humidity levels in the sub-floor, lifting of lino and vinyl floor tiles, pest invasion such as termites, cockroaches and flees, musty odours, bad smells and a general accumulation of damp levels under and within your home. But please keep in mind, that the installation of vents will not treat or cure a rising damp or lateral damp problem as mentioned by some other so called professionals on their websites and brochures.

 

Types of Vents

  • Sub-floor vents

    Buildings with timber floors, built up on piers suffer from a lack of ventilation due to a bad cross flow of air. Installation of brass mesh wire sub-floor vents allow a natural cross flow of air under your home. These vents come in an array of sizes and colours to match the existing brickwork. Plain coloured vents can also be installed and painted later to match any coloured desired. Each vent is constructed from pre-coloured concrete with corrosion resistant brass mesh wire to ensure durability. Sub-floor vents provide a natural air flow throughout the property which minimises condensation, inhibits the growth of mould and maximises the sub-floor air flow.

    A good cross flow of air is achieved when air travels through a vent on one side of the building, through the sub floor area, and out the other opposing side through another vent. Sub-floor vents must not be below the soil level, and must not be covered by gardens or landscaping. The sub-floor area must not have hinderance from rubble or any other form of obstruction. The vents should be regularly checked and cleaned of grass clippings, leaves, etc, to ensure maximum air flow is achieved.

  • External louvre vents

    Louvre terracotta vents are also known as clay brick vents. Made from natural clay they blend easily into existings walls due to their subtle earth tones.

    The louvre vent, when teamed with an internal plaster vent, will also act as an upper wall ventilator. External louvre/interior plaster vents are installed up the higher part of the the wall, closer to the ceiling height. These vents allow stale, musty air to expell from the internal living areas of a dwelling, replacing it with clean fresh air. The louvre design of the vent stops any rain from entering.

    When brickwork is not present, an alternative Aluminium non corrosive vent would be installed into walls that consist of fibro, timber and other masonry. These vents have a brushed matt silver/shiny silver look and are asthetically pleasing to any existing wall.
    Internal ventilation systems
  • Internal Plaster Vents

    As mentioned the internal plaster vents are installed to the interior upper wall, closer to the ceiling height. There are many designs to choose from plain to Heritage looking patterns. Allowing stale air to pass into the plaster vent and expelling it through the adjacent external louvre vent enables a healthier living environment.

  • Ecofan - Mechanical ventilation

    Homes that are terrace houses with common walls, duplexes, have mounds of earth, rubble or stored goods in the sub-floor area, errected on sloping blocks or poor access to the sub-floor area do not achieve a consistent cross flow of air. In these cases it may be necessary to install a fan to extract and replace the air mechanically.The Ecofan is a form of mechanical ventilation

    Ecofans are installed to improve sub-floor air quality and reduce humidity levels beneath the floor. This 23cm diameter fan consists of five blades and an electronic brushless D.C motor. The fan is installed in an aluminium powdercoated frame.

    The Ecofan extracts 4,000 litres per minute of damp sub-floor air. This air is then replaced at the same time with external fresh air. The air is sucked in through the wall grills placed opposite the fan. The Ecofan is fully controlled by power . If the fan was to run continuously, it would cost less than an extra $6 (Aud) per year in energy.

    The Ecofan Is installed in the sub-floor brickwork by removing one brick and part removal of adjacent bricks above and below. No electrician is required. The 12v adaptor is supplied for connection to a standard power point.
