An extra layer of air keeps your building cooler. In most homes, the sun hits your cladding and the heat from the sun is transferred directly from the cladding into your walls. This makes your building warmer than necessary. The air vents provides better ventilation and keep your home cooler. Flat roof top air vents bring daylight and fresh air into your flat roof home. Most houses have air vents in the roof of buildings to vent the humidity and hot air and those openings can be the major entry point for mosquitoes and insects. Why not prevent the problem before it occurs?
