Alternatively, EWI is breathable or vapor open, absorbing and releasing moisture quickly, allowing vapor to pass through the walls and keep the structure dry. You won’t have to compromise on thermal and energy performance when your home is vapor open because it’s different from being leaky. The moisture balance of a solid wall home can be maintained by continuing the open vapor concept.
