Are SIP homes too tight for good indoor health?
A.) No. Research indicates that the best way to provide a building (such as a home or office) with good indoor air quality requires two essential steps. 1.) The building has to be built as tightly as practical; it is easier to control air movements in a tight home than in a leaky one. 2.) The building must have modern, upgraded mechanical ventilation features in the HVAC system so that it provides an appropriate and steady flow of fresh air. These modern HVAC features also add energy-efficiency.
