Thermiser Max® Insulated Rolling Door

Model Number: ESD30

Our Thermiser Max® Insulated Rolling Door is the most energy-efficient insulated rolling 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 Thermiser Max Insulated Rolling Doors meet ASHRAE ®90.1 and IECC®(International Energy Conservation Code) 2012 Section C402.4.3 Air Infiltration requirements with an independently tested value of less than .3 CFM/FT2.

The doors provide all the benefits of our standard rolling door offering, plus:

  • Climate Control: Our exclusive patent-pending sealing system, (with thermally broken guide assemblies and a lintel seal), together with the insulated curtain, provides impressive reductions in air infiltration and thermal transference
  • Security: Our insulated curtain design features two layers of metal with foam in between, making the door stronger and more secure
  • Sound Reduction: The Sound Transmission Class (STC) rating is up to 32 for the entire assembly, as tested per ASTM E90 (with a complete, operable assembly)

These doors are constructed for daily use and can withstand operation of up to 20 cycles per day - that’s 50,000 cycles for the lifetime of the door.

Materials and Finishes

Double skin interlocking roll formed interior and exterior metal slats :

  • R-value of 8.0 as calculated using the ASHRAE Handbook of Fundamentals

Slats are filled with 7/8" thick closed cell pressure foamed in place urethane insulation:

  • Flame Spread Index of 0
  • Smoke Developed Index of 10 as tested per ASTM E84
  • CFC-free process with an Ozone Depletion Potential rating of 0
  • Meets foam plastic insulation requirements of the 2012 IBC®, section 2603

Slats available in:

Available Operators

Our doors can open by motor, chain, hand-crank, or push-up operation, depending on size, weight and/or frequency of operation.

Model MG - A medium duty operator for doors that will cycle less than 20 times per day

Model SG - A super duty, full logic operator for larger doors or doors that may periodically cycle more than 20 times per day


Chain Diverter for MGH Operators

This option moves the auxiliary chain out of the clear opening and to the side of the door - enabling free movement through the door and making a chain bag unnecessary.

Hood and Operator Covers

Metal cover to protect the coil or operator from exterior weather, debris or to meet OSHA or UL 325 safety requirements.

Powder Coated Graphics

Permanent, durable faux finishes are available for rolling door curtains. There are six wood grain options as well as the ability to use custom graphics, photos or logos. Powder coated graphics give your doors a seamless, upscale look - either blending into the existing building architecture or transforming a building necessity into a work of art.

We can apply powder coated graphics to rolling doors 12’ wide and under, on standard, insulated or perforated slats.

SpectraShield™ Powder Coating

Polyester finish in more than 180 colors for durability, aesthetics, superior finish life and cost effectiveness.

Trim Package
In applications where exterior aesthetics are important, such as hotels, condominiums, convention centers and parking garages, the addition of a trim package can cover unsightly hardware and contribute to the building's architecture.

Vinyl Graphics

Add durable, full-color images to your curtains and hoods. Great for school logos and turning unused door space into profitable sponsorship opportunities in stadiums, amusement parks and retail stores.

Vision Windows
Improve aesthetics and visibility with one- or two-way windows incorporated in the curtain.

Performance Upgrades

High Cycle Springs
Heavy duty springs manufactured to withstand cycles of 100,000.

Seismic Performance Validation

We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall or Between Jambs to steel or masonry. Seismic performance validation is per ASCE 7-05.

Safety and Protection

Entrapment Protection Devices

Entrapment protection devices ensure that a motorized door or grille will not close on an object. If an object enters path of closure, the entrapment protection device will stop the door or grille from closing and return it to the fully open position.

Guide-Mounted Interlocks
An electrical cutout switch to prevent motor operation if locking device is not first disengaged.

HDBB (Heavy Duty Bottom Bar)

The HDBB is 350% stronger than traditional bottom bars, preventing forklift damage to your Service or Insulated Door. The HDBB can pay for itself after the first impact and significantly reduce future maintenance costs.


A wide variety of locking options are available to meet your security needs.

Motor Mounted Interlock

An overload sensing device that prevents damage if motor operation is attempted when the door or grille is locked. Field wired guide mounted interlocks are no longer necessary.


RapidResponse doors are provided with 3' or 6' of extra curtain, an impactable bottom bar and removable lower guide sections. These features allow for faster repair of slat damage, reducing downtime and maximizing the lifetime value of your door.

Rolling Door Protector (RDP)

The RDP eliminates costly fork truck damage to coiling doors by creating a physical barrier at the top of the door that absorbs impacts.

Wind Load
Can be configured to withstand the full range of specific wind load requirements including missile impact ratings.

Unique Design Solutions

Sloping or Irregular Openings
Our special bottom bar designs can address these conditions.

Superimposed Doors
Combine two different curtains on the same opening. Typically, an insulated door is used in conjunction with an open design rolling grille to provide ventilation. When extreme weather or sound resistance is desired, we can provide superimposed/double insulated curtain assemblies.
