Polyurethane Core No voids, no hollow spots. R-15 insulating value-five times better than wood doors; nearly twice that of polystyrene doors! Saves energy, winter and summer.

True Thermal Break Not all steel entry doors have one! Vinyl thermal break locks skins together, while separating exterior and interior steel surfaces, to provide a thermal break that minimizes heat loss, condensation and ice buildup on inner skin regardless of outside temperature.

Triple Contact Bottom Sweep Twin compression tubes and extruded vinyl sweep-blade mate with threshold to seal door bottom and prevent major energy loss. No leaks, drafts, ice buildup.

Rigid Steel Skin Strong and secure. Won't warp, sag, shrink or swell like wood doors. Rust-free service provided by 24-gauge galvanized steel.

Reinforced Lock Preparation Provides rigid base for locksets. Discourage intruders. For use with all frames and most types of security hardware.

12-Gauge Hinge Reinforcement Plate riveted within door, which eliminates sag.
