System and method for attaching architectural moldings and insulation sheets to buildings

A method for attaching a unit of construction material adapted to engage a building, wherein the unit includes a body of light-weight plastic having a plurality of sides, a back wall, and a top wall, said method comprising:

• embedding an elongated strip of rigid material entirely in said body, mounting said unit on the building such that the back wall of the unit directly contacts an exterior or interior surface of the building, and applying fasteners having heads and shanks through the body and strip of rigid material and in engagement with the building and where the heads of the fasteners contact and bear against said strip and said shanks extend first through the body, then the strip and into the building thereby attaching the unit to the building.

A unit of construction material for attachment to a building, wherein said unit includes a body having a core of light-weight material having a plurality of sides, a back wall, and a top wall, means for mounting said unit onto said building with headed fasteners such that the back wall of the unit directly contacts an exterior or interior surface of the building, said mounting means including an elongated strip of substantially rigid material entirely embedded in said core against which a head of a fastener is adapted to contact when extending the fastener through the unit and strip of material and into the building for attaching the body to the building, said unit of construction material being a molding wherein the molding includes an elongated body having a decorative cross-sectional shape with a base wall and an outer formed face, a coating of substantially rigid material over said outer formed face adapted to be painted or otherwise further coated with a finish material, and said mounting means further including a channel extending in said core of said body substantially parallel to said base wall, whereby said channel receives said strip of substantially rigid material.

A unit of construction material for attachment to a building, wherein said unit includes a body having a core of light-weight material having a plurality of sides, a back wall, and a top wall, means for mounting said unit onto said building with headed fasteners such that the back wall of the unit directly contacts an exterior or interior surface of the building, said mounting means including an elongated strip of substantially rigid material entirely embedded in said core against which a head of a fastener is adapted to contact when extending the fastener through the unit and strip of material and into the building for attaching the body to the building, said unit of construction material comprising an insulation sheet being formed of light-weight plastic material and including a rectangularly shaped body, and means for mounting said sheet onto such building or structure with headed fasteners, said mounting means for said sheet including a strip of substantially rigid material embedded in said sheet against which a head of a fastener is adapted to contact and be supported when extending the fastener through the sheet and into said building, and said mounting means further including a channel extending in said body substantially parallel to said back wall, whereby said channel receives said strip of substantially rigid material.
