Each of the web trusses comprises at least one top cord, a bottom cord and a plurality of webs joining the cords together. A vapor barrier is sandwiched between the bottom cords of the web trusses and the inner sheathing. A layer of insulation extends upwardly from the vapor barrier a height less than the height of the insulated roof panel in order to allow air to flow over the insulation. Sleeves built in to the web trusses allow fasteners of a length less than the height of the panel to secure the roof panel to timber frame members.

  • Patent number: 5953883
    Abstract: An insulated wall panel comprising a bottom, a plurality of inner members, a plurality of outer members, spacers between the inner members and the outer members, an insulation layer, an exterior sheathing, a vapor barrier, a top member and a planar interior wall. The insulated wall panel has a dead air space located just inside of a cavity filled with insulation. The wall panel is adapted to be secured to the frame of a timber frame home without fasteners passing through the entire depth of the panel. Fasteners secure the inner members of the panel only to the frame without destroying the integrity of the insulated wall panel.
