More about this product

Thermiser Max® Insulated Rolling 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. They 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 30 for the curtain and up to 22 for the entire assembly, as tested per ASTM E90 (with a complete, operable assembly)

Materials and Finishes

- Configuration:  Double skin interlocking roll formed interior and exterior metal slats (R-value of 8.0 as calculated using the ASHRAE Handbook of Fundamentals)

Vinyl Graphics
Vinyl Graphics

- 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.  
- 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.
