Fiberglass entry door systems, sold through dealers

Standard features, not upgrades

Many of the features below are upgrade options on other doors. On a Signamark door they come standard: high-definition panel embossments and a woodgrain that resembles real wood, a 16" wood lock block with a jamb security plate, composite on all six sides of the door slab (except fire-rated doors), a PVC jamb designed to resist rot, ball bearing hinges, an injected polyurethane foam core, and triple-pane decorative glass.
