What is Attic Ventilation?
dafa888,dafa888大发平台 "Ventilate" comes from the Latin word for "to fan." Simply put, it's the action of moving air. Out with the hot. In with the cool. And that's exactly how ventilation works. It provides conditions that allow air to flow. Every time stale, overheated air in your home or attic is vented out and fresh air is pulled in to replace it, you have what is known as an "air exchange.".....
Evaluate your Ventilation needs
dafa888,dafa888大发平台There are a number of variables to consider when selecting the most effective ventilation system for your home. Before you make any decisions, go up into your attic and take a look around. A sure sign of poor ventilation is an unbearably hot attic in the summer. Another thing to check is evidence of moisture, such as mold, mildew, rusted nail heads, damp or compressed insulation or wood rot.
