Why Dealers Tie-in With Plen-Wood

The Plen-Wood system is a heating and cooling alternative, employing standard construction methods and materials to provide significant economies in construction and energy.

As simple as it is effective, the structure is built with a tightly sealed underfloor space. The entire underfloor area is used as a sealed plenum chamber, where conditioned air is kept under slight pressure. A conventional downflow HVAC unit warms or cools the air, which is directed to the plenum and distributed through floor registers to the living space above.

Various foundation systems, such as the Permanent Wood Foundation (formerly the All-Weather Wood Foundation), poured concrete or concrete block may be used. Regardless of the foundation choice, standard construction methods are used except that foundation vents are omitted.

After the foundation is completed, a vapor barrier is laid over the ground and draped down the inside of the foundation wall. The film is secured over the sills and later attached to the rim joists. After the floor joists are installed, blanket insulation is applied to the inside perimeter of the foundation wall and rim joists. A strip of batt insulation is also laid flat on the ground over the vapor barrier inside the foundation perimeter. American Plywood Association (APA) rated sheathing or Sturd-I-Floor is glued and nailed to joists.

Once the building is closed in, a conventional downflow heating and air conditioning unit is installed. Vents and/or louvered doors are installed in the HVAC area for return air. If the unit is located at the far end of the building, or if the building has an H-, T- or Lshape, stub ducts may be needed. Otherwise, air circulation is accomplished simply by cutting holes in the floor between joists for installation of standard, adjustable floor registers. Metal pan receptacles are suspended below each opening to prevent debris from collecting in the plenum.

Finally, a hatch is provided for access to the plenum. There are no foundation vents or exterior access to the underfloor space.
