The Door House



Unequalled adhesion of the steel skins to the polyurethane core is backed by our 7 year warranty against de-lamination. This rugged door combined with its heavy duty hardware will allow this door to function smoothly for years and years to come.


The THERM-O-DOR offers excellent protection against break-ins. This security is provided by a tough section made up of a core of polyurethane covered with two steel skins. The door face is then combined with heavy duty hardware and interior side locks to ensure maximum security.

Energy Saving

Air infiltration and conductive energy loss is minimized with intermediate between section joint seals; top, bottom, and side weather seals and a thermal-break between the interior and exterior steel surfaces. These combined features provide a door that is totally energy efficient.

Advanced Construction

Many special features are built into the THERM-O-DOR, including between joint seals, ship-lap edge to provide a drip-free door opening and thermal-break. In addition, THERM-O-DOR features an exclusive mechanical interlock (Patent pending) providing a positive mechanical lock of the exterior and interior skins. These features combined with the superior quality adhesion of the urethane to the steel face, makes this door the strongest of its type in the world.

Virtually Maintenance Fee

The finish on this door is a pre-painted baked on two coat polyester finish on both sides - means years of maintenance free operation.
