Ventilation plays a key role in keeping mould and mildew out of your home. Having adequate cross flow ventilation in your sub-floor helps prevent, cure or reduce timber decay, cupping of floor boards, and risk of termite attack. Aleta Vents also allow natural light into your sub-floor making it less desirable for termites and other nasties. Aleta's Brass Wire Mesh Vent (Hi flow static vents) give up to 23,800 Sq mm of ventilation per vent.
