Advanced Performance in an Insulated Rolling Door System

This door system presents the most advanced thermal performance values published by any major US manufacturer of insulated rolling steel doors, with an R-value* of 10.9, U-value** of 0.09 and a tested installed U-factor† of 0.84. When compared to the International Energy Conservation Code (IECC) 2012 requirements, the Stormtite™ AP Model 627 far surpasses these. The superior construction of this rolling service door and the advanced design of the perimeter seals offer superior door protection against air leakage. The innovative EPDM triple-finned guide brush weatherseals (located on interior and exterior of guide), work in tandem with the hood baffle and bottom bar weather seals to reduce air leakage through the entire door system perimeter.​​​​​

The sound performance of the Stormtite™ AP Model 627 furnishes a through curtain Sound Transmission Class (STC) rating of 28 and installed system rating of 21. The higher the STC rating the better the buffering is from the transmission of sound through and around the door. This insulated door system also includes a flame spread and smoke index of class A or 1, the highest rating possible and complies with National Fire Protection Association (NFPA), Underwriters Laboratories (UL) and International Building Code (IBC) requirements.

Stormtite™ Secures Against Elements and Forced Entry

The Stormtite™ AP Model 627 is constructed of interlocking slats with endlocks and/or windlocks. This design supplies resistance against forced exterior entry and several interior lock options can supply additional security. The 627 delivers 20 psf (design pressure) wind load protection, which is equivalent to approximately 90 to 110 mph wind speed (comparable to hurricane force wind category 1 to 2). This model can be built to accommodate higher wind loading upon request.

Flexibility in Operation

This Stormtite™ AP door system comes with chain hoist operation standard; crank and motor operation options are also available. The varied options of operation and mounting (left or right handed) afford flexibility to meet the needs of the facility and application.

Many Options, Customized Solutions

The Stormtite™ AP Model 627 is available with a number of options to meet individual application needs. The large insulated vision lite features thick dual-wall polycarbonate which affords advanced insulation properties as well as maximum visibility and light transmittance. Slat options include a choice of steel (standard), stainless steel or aluminum. Finish options include a choice of 4 standard colors as well as the PowderGuard® Premium powder coat finish in approximately 200 colors or color-matched to specification. The PowderGuard® Zinc and PowderGuard® Weathered finishes are also available for the door curtain as well as bottom bar angles and guides.

Special application options include oversized doors, combination doors (2 doors on a single head plate), and pass doors. Ask your Overhead Door™ Distributor for more information about the special application options.​

_{* R-value is a measure of thermal efficiency. The higher the R-value the greater the insulating properties of the door. Overhead Door Corporation uses a calculated door curtain R-value for our insulated doors.}

_{** U-value is a measure of the flow of heat through an insulating or building material: the lower the U-value, the better the insulating ability. U-value is the inverse of R-value.}

_{† Installed U-Factor – A tested value of actual energy loss – whether heat or cold – of an installed door, wall, or window assembly. The lower the number the lower the energy loss and therefore the better the thermal performance. U-factor will vary between 0.66 and 1.00 depending on finish and color selection. For best U-factor, choose finish and color with high solar reflectance (bright colors).​​​​​}
