| (54) | Insulated siding and method for its application |
| (57) An insulated siding comprises a panel (10) of hardboard attached by adhesive to a
polystyrene foam layer (11). The rear surface (18) of the foam layer is parallel to
the front face (14) of the hardboard panel. The upper and lower surfaces (19, 24)
of the foam have parallel V-shape with the upper surface having the V inward for collection
of moisture. The panels are installed by over-lapping the hardboard of two adjacent
panels to allow the foam layers to interlock leaving a space for a sponge layer (37).
Channels (27, 29) are formed in the foam downwardly between the hardboard and the
foam and across the bottom of the foam to provide an intercommunicating network to
transmit moisture vapor. The panels can be nailed to the front face of a building
using a spacer device (30) to set the distance of the upper edge of the panel from
the front face of the building to prevent compression of the foam. |
