As well, the follow of using ‘slit bricks’ (bricks on their sides with a spot between them) rather than the builder installing correct air vents isn't really helpful as a result of the small opening between the bricks blocks up. This state of affairs can easily be fastened by knocking out the bricks and installing Aleta high-move vents.

All followers are rated for 50,000 hrs. Exopest can simply set up Eco-friendly, solar-powered or low-voltage 12v subfloor ventilation methods. The difference is instant, the vitality working the system is free from the sun (for solar-powered techniques) and leads to a humid-free surroundings with no carbon emissions.


In order to counteract foraging worker termites, that are attracted by moisture, Exopest makes use of solar-powered or low-voltage 12v electrical fans and air vents to maximize subfloor air flow. Subfloor followers and vents additionally reduce mould and fungi growth (see the photos beneath) under the ground and discourage foraging termites and borer assault.


If the void has internal sleeper partitions, provision should be made for ventilation to pass through these barriers and give protection, so as no a part of the floor void is left to stagnate and become prone to moisture. As all manufacturers’ underfloor ventilators have different airflows, an open specification may lead to using products which give a lower rate of ventilation than originally intended leaving the sub-ground beneath ventilated. The Building Regulations Approved Document C states suspended timber floors and suspended concrete flooring (together with block and beam) have a provision for ventilation on two opposing external walls of not lower than 1500mm² per metre run of external wall or 500mm² per metre² of flooring space, whichever works out to give the greater quantity of air flow.
