When you need an interior or exterior closure option that is secure, durable, customizable and compact - you need a Cornell Service Door. Our rolling steel Service Doors feature a rugged design manufactured with quality materials that lower the total cost of ownership. And, because we custom build each door to your exact aesthetic specifications, we can create a door that seamlessly fits into your existing designs.

Our Thermiser Max® Insulated Rolling Door is the most energy-efficient insulated door available today, with the certifications to prove it. IECC, ASHRAE, LEED -  this door has it all while decreasing air infiltration by 94% versus standard products. And, because we care about the environment as much as you do, the door can help you achieve up to 38 points in five LEED certification credit categories.

Our energy-efficient Thermiser® Insulated Rolling Doors combines the robustness of a rolling steel door with foamed in place insulation. This offers superior protection against the elements, improved security and reduced sound transmission - both outside your building, sealing the building envelope, and inside.

Fire and smoke must be stopped in their tracks to save property and, more importantly, protect lives. Our advanced fire door systems compartmentalize a fire event quickly allowing adequate time for egress from the building. They have become the clear and reliable choice for building owners and designers who demand the highest level of life safety and fire protection available with the lowest cost of ownership in a modern, easily integrated package.
