The Kimberley™ Solar Roof Ventilator is designed to take advantage of free and clean solar energy to cool down your home by drawing hot air out of your roof space and replacing it with cooler air from outside. Solar Roof Ventilators will also protect your home from airborne moisture related damage to building materials. In every home, moisture and humid air in a roof cavity condense into water droplets. Like external heat generated by the suns rays, other interior activities create moisture in the air. Activities such as showering, cooking and doing the laundry cause rising moisture which can lead to mildews that damage plasterboard, weaken building materials and lead to electrical and health problems.
