Thermiser Max® Insulated Rolling Door
Thermal efficiency for demanding commercial spaces.
The collection
Commercial insulated rolling doors can help businesses control temperature at large exterior openings. Cornell manufactures Thermiser Max®, Model ESD30, for commercial applications where energy performance matters.
Its double-wall steel curtain contains 7/8-inch closed-cell polyurethane insulation with an R-value of 8. A patented perimeter seal and thermally broken guides work together to reduce heat transfer and air infiltration.
For warehouses, distribution facilities, manufacturing plants, and climate-controlled spaces, commercial insulated rolling doors can help protect conditioned interiors.
Commercial Insulated Rolling Doors for Thermal Efficiency
Keep conditioned areas better separated.
Commercial insulated rolling doors are engineered to limit unwanted air movement and heat transfer.
- 0.82 U-factor: Tested complete-assembly thermal performance.
- 94% less air infiltration: Compared with standard non-insulated rolling doors.
- R-value 8: Insulated curtain construction adds thermal resistance.
- Perimeter sealing: Helps tighten the opening.
- Thermal breaks: Guides reduce conductive heat transfer.
- LEED contribution: Can contribute across five LEED credit categories.
Commercial insulated rolling doors can support efficient building performance.

Construction Features for Commercial Insulated Rolling Doors
Built around the curtain.
Commercial insulated rolling doors use double-skin interlocking steel slats with insulation foamed into the curtain. The 7/8-inch urethane insulation has a Flame Spread Index of 0 and Smoke Developed Index of 10 under ASTM E84.
- Galvanized steel: Multiple gauges and finishes are available.
- Stainless steel: 300 and 316 series options are offered.
- Aluminum: Mill, clear, and color-anodized finishes are available.
- Mounting: Face-of-wall and between-jamb installations are available.
- Weather protection: A hood shields the curtain and operating components.
Commercial insulated rolling doors can be tailored to environmental and performance requirements.

Operational Choices for Commercial Facilities
Match the door to daily use.
Commercial insulated rolling doors are designed for up to 20 cycles per day and 50,000 lifetime cycles. High-cycle construction is available when greater frequency is required.
Operator choices include motor, chain, hand-crank, and push-up operation based on size, weight, and usage. Model MG is intended for medium-duty applications, while Model SG provides super-duty operation for larger doors or doors that may periodically exceed 20 cycles per day.
Cornell manufactures Thermiser Max® for commercial properties needing insulation, security, and dependable access.
