Commercial buildings require high-performance products due to the fact that they often contain a large amount of open-door space at entry points and within warehouses, conference rooms, and more. Each of these access points must be carefully assessed for the safety, security, and efficiency of any commercial building. Whether your project is a new construction build or an upgrade to an existing space, Cornell offers a variety of solutions through Alder’s.

As the leading manufacturer of custom closures for commercial applications, Cornell offers custom doors that combine durability with compact design and affordability through various styles and designs. Their overhead rolling door solutions and other product lines are used worldwide in retail spaces, commercial warehouses, apartment garages, and anywhere security, protection, and ready access are a priority.

Cornell rolling steel doors can even be incorporated into LEED projects and built to suit a variety of codes and requirements.

A complete line of rolling service doors and closure
products is available to suit your space:

Security Grilles offer the ultimate protection with a wide range of customization options for security doors, including logo etching. These roll-up doors prevent break-ins and protect your investment while needing little ongoing maintenance.

Fire Rated Products meet all national fire codes and are UL-rated to provide peace of mind for your building’s inhabitants. Cornell offers fire-rated doors, counter shutters, curtains for sealing elevator shafts, and more.

Insulated Garage Doors prevent heat transfer and improve the energy efficiency of your HVAC system. These insulated doors reduce utility costs and minimize noise, making them perfect closure solutions for high-traffic areas.

High-Performance Roll-Up Garage Doors operate quickly and at high speeds (at rates of 24 inches per second), while grilles open three times faster than traditional commercial door products, keeping your business secure and increasing the efficiency of your warehouse or loading dock. These rolling grilles are also optimal for parking garages because of their speed and high-security features.

Rolling Counter Doors are optimal for securing compact areas above a counter space, either indoors or outdoors. These high-performance rolling doors are made to last and offer a wide variety of finishes and customization options.

Side-Folding Closures operate best where space is at a premium, and function like an accordion with slats that collapse to create division and partition for interior rooms and hallways, as well as retail spaces, airports, and more.
