Is ventilation in my attic as important as the insulation?
Yes ventilation is as important as the insulation in a typical ventilated attic. Ventilation is important for a number of reasons;
- Ventilation will allow for fresh air to come in and help exhaust moisture
- Getting rid of excessive moisture reduces chances of mold growth and the cost associated
- Healthier home no mold growth and less airborne pollutants entering home
- As R-Value increases in the middle of your attic the heat loss at soffit area/roof wall junction increases and along with this comes moisture, ventilation stops moisture building up under the sheathing at the soffit area.
