How important is ventilation?
SIP buildings are extremely airtight and require mechanical ventilation. Ventilation systems bring fresh air into the building in controlled amounts and exhaust moisture laden and stale air to the outside. By limiting air exchange to controlled ventilation systems, SIP homes allow for all incoming air to be filtered for allergens and dehumidified, amounting to better indoor air quality. Proper ventilation is important in all homes to preserve indoor air quality.
Attic ventilation serves several purposes during all four seasons of the year, among them being added comfort, protection against damage to materials and structure, and reduced energy consumption. But the most important function is to provide a uniform flow of cool air along the underside of the roof sheathing which in turn carries the heat out of the attic. Proper ventilation is also required in order to validate the manufacturer’s warranty for your roofing system.
