Control of heat, air, and moisture by the Ecocor PassivWall™ make our houses last.
Water, in all its forms, is the enemy of a building. Moisture will cause a building to rot, cause doors and windows to fail, and create a habitat for mold inside walls that make a house
unhealthy to live in.
Science teaches us some important things about moisture, air, and heat:
Air carries a surprising amount of water vapor through extremely small holes in the walls and floors and ceilings of a home. In the course of 24 hours, 12.7 oz. of vapor can accumulate in a
wall through a 1mm x 1mm hole. As much as 28 oz. of vapor can be transported through the same hole at 20 Pascals of pressure.
So, to build a durable building, you need to regulate heat, air, and moisture in all its forms, and each needs to stay in its place. An Ecocor PassivWall™ has dedicated control layers to do
exactly that. In the illustration to the left, you can see the dedicated layers that control air infiltration, heat flow, and vapor. The Weather-Resistant Barrier (WRB) is a Thermoplastic
Elastomer Ether Ester (TEEE) fabric. It is completely waterproof and extremely robust and allows vapor to escape to the exterior. This fabric is meticulously flashed and taped so that liquid
water has no entry point. Likewise, the airtight layer that controls the movement of air and moisture is carefully taped and sealed at every joint and penetration. There are no cracks through
which air can move and carry water into wall cavities. Importantly, that airtight layer is located well inside the wall, where it is unlikely to be damaged by the activities of building and
living in the house.
18 inches of Continuous Insulation is installed both in the factory and in the field creating a Thermal bridge free wall that keeps the heating and cooling inside the home and the elements on
the outside. Because the wall is so well insulated, it is impossible for condensation to occur on the structural components of the walls and roof. This ensures the structure remains dry and
durable for generations.
