Roof and Floor Ventilation
Insulation and Ventilation go hand in hand…
While insulation is the most efficient means to keep your energy bills low it can still not be enough, on it’s own, to allow hot air to leave your home during the hottest periods of the year. During these extreme hot periods the temperature in your roof can climb to over 70°C. In these conditions even the best insulation needs the help of ventilation to cool your home quicker.
This is where ventilation comes in. Effective ventilation in Summer, expels hot air from your roof by replacing it with cooler air from outside, allowing your insulation to work more efficiently. In Winter it will continue to remove any moist air that may lead to mould problems within the building.
Increased ventilation throughout sub-floors is another way of reducing the another contributor to mould and musky odours.
|Roof ventilation improves the performance of ceiling insulation by drawing cooler outside air through the roof space and helps reduce the temperatures that can build up on hot days. Ducted air-conditioning benefits from the ducting not being exposed to the extreme temperatures that can build up in Summer. Also as evening falls, the cooler night air gets pulled through the roof space, cooling the insulation down, ready to start again next morning. In Winter, attic ventilation is good to remove any excess moisture that might build up in a ceiling from the situation where warm, moist air might be meeting colder outside temperatures with the risk of Condensation occurring leading to mould problems.|
|Many sub floor spaces suffer from poor outside air flow and can give rise to musky odours, mould and damaging pests such as termites when moisture content builds up in timber floors. An inexpensive solution is to ensure that proper drainage has been utilised and then install a mechanical ventilator to force a constant air flow over the sub floor areas.The purpose of sub floor ventilation is to replace highly humid sub floor air with a less humid and cleaner external air flow.|
|In addition to providing ventilation solutions to domestic houses we also have experience dealing with ventilation for large scale structures such as sheds, warehouses and factories.Our experience helps us calculate the volume of the premises and match it to the appropriate industrial ventilator to ensure a nominated number of air-changes per hour.|
