Home Insulation Services - Do I have enough Attic Ventilation?

Attic Ventilation is important to make sure the heat can escape. Without the proper amount of ventilation in the attic heat and moisture will build. With to much attic ventilation or improper ventilation the same issues will occur. Before adding additional ventilation proper air sealing should be done. During the Energy Audit the attic insulation will be measured and the net free ventilation will be calculated. The blower door will be used to determine the house leakage. After all the measurements are taken the proper recommendations can be made. Without following the proper diagnostic steps contractors are performing malpractice.
