What is ventilation?
You’ve probably heard that ventilation is very important, but what exactly is ventilation?
Ventilation is simply the process of providing a continuous supply of outdoor air to the attic space of a home or building.
What is proper ventilation?
Simply having ventilation in an attic space, however, won’t properly ventilate a home. In order to have proper ventilation, ventilation needs must be specifically calculated based on attic space square footage and correctly installed. Calculators here on lomanco.com make it easy to calculate how much ventilation is needed.
Proper ventilation consists of 50% intake ventilation placed near the lower part of the attic space, and 50% exhaust ventilation placed near or at the roof peak. The exhaust ventilation should be at least 3 feet higher than the intake ventilation.
It is estimated that as many as 9 out of 10 US homes have some form of improper ventilation. Fortunately for homeowners, contractors, and roofers, Lomanco offers a full line of home ventilation products to supply the proper amount of ventilation to existing and new construction.
