Remote Wall System Monitoring

The main office walls are constructed using the Exterior Membrane Outside-insulation Technique (REMOTE ). This system is a modification of a Canadianvapproach that sealed the entire building envelope with a self-adhering membrane and layers of rigid insulation.

In REMOTE, just the exterior walls are built in this manner; ceilings and roofs are constructed with more conventional cold climate building techniques. The REMOTE wall is constructed with the vapor and weather barrier membrane on the outside of the structural wall members. On top of this membrane and to the exterior, layers of rigid insulation are applied.

Typical construction in cold climates places the vapor barrier on the inside of the wall with insulation filling the wall cavity. There is a tendency for vapor to condense inside this kind of wall and for the wall cavity to have difficulty drying. This condition can result in a number of problems including mold growth and rot. The REMOTE wall eliminates trapped moisture and condensing of vapor in the wall. The wall also has the ability to dry in the event of moisture intrusion or condensing.

We are studying the use of two different types of interior fiberglass batt insulation by Johns Manville are being compared. The goal is to study the wall moisture content and temperature over time to see how each performs. Moisture and temperature sensors have been placed in a line through the wall at each change in material to monitor the movement of heat and vapor.
