All About The Insulation

The best way to achieve appropriate ventilation and good airflow is through proper insulation. To protect a house from heat gain or loss, it’s ideal to include a gap-free layer of insulation on the attic floor and a vapor retarder under the insulation next to the ceiling to stop moisture from rising into the attic. Having open, vented spaces that allow air to pass freely with at least one inch between the insulation and roof sheathing is also ideal.
