Sheathing and moisture

Many of you know, Landus is involved in the development of systems and products for the building industry – predominantly focused on keeping building materials structurally sound. In most cases, this means keeping the wood dry or make sure it has drying potential if it does get wet.

A building envelope is defined as the physical separator between the conditioned and unconditioned environment of a building including the resistance to air, water, heat, light, and noise transfer.

The product we have chosen to use on our new house is one made by Georgia Pacific called Forcefield. This product allows the seams of the wood panels to be taped creating an air and water barrier for the house. A sheathing with taped seams is a great improvement to the heavily stapled house wrap that has been the standard for several decades now.

Another strategy Landus has employed to help keep water out of our new house, is the use of vertical seams. Because of the tall ceilings and the overhang of the roof, placing the panels vertically keeps the number of horizontal seems down. By using 10′ panels, some walls won’t require any horizontal seams and above 10′ the horizontal seems we do have are under the overhang.
