What is a blower door test?
A blower door test is a way to check how air-tight a structure is. It is designed to check for air leaks in walls, attics, and mechanical penetrations. While a blower door test does not evaluate how well a structure is insulated, it can reveal drafty walls and air-bypass situations that could undermine otherwise well insulated wall assemblies. A poorly sealed houses will have higher utility bills, issues with comfort, and potential mold an rot issues caused by moisture. Blower door testing can be carried out on residential homes, commercial structures, and industrial buildings. In some states they are required by code for residential areas. (Always check with your local building codes)
