Home Remodeling Virginia – Does my house need proper ventilation as well as adequate insulation?
For best results you need to use the combined power of insulation and ventilation. Having good ventilation means a better air flow within the house, which prevents the forming of moisture.
The simplest way to improve ventilation in your home is to create two vent openings, one on the rooftop that will let fresh air into the home, and one in the gables to let the warm air from the house out.
Improving the ventilation in your home is especially important after you insulate your attic.
