The outstanding features and benefits of the Haas Door 800 Series have made them the door of choice among commercial and industrial architects. The 800 series insulated sectional steel doors feature a full 3″ pressure-injected core of high-density CFC-free polyurethane foam insulation, with an R-Value of 25.8 – the highest in the commercial door industry. Therma-Pro™ is exceptionally strong. All Therma-Pro™ doors are reinforced with roll-formed galvanized steel struts and double-end hinges as required to meet or exceed local wind load specifications. Haas Door’s Therma-Pro™ is the ideal door for applications that require both maximum energy efficiency and strength


1 Maximum Energy Efficiency

A 3″ pressure-injected core of high-density CFC-free polyurethane foam insulation is bonded to the inner surfaces of the exterior and interior face sheets or panels. To ensure maximum energy efficiency and strength, the foam is pressure-injected into each section of the door at approximately 2.5 pounds per cubic foot and is carefully cured in a temperature-controlled environment

2 All-Steel Construction

Face sheets are heavy-duty, roll-formed, galvanized steel. Model CHT-816 features a 26-gauge, wood-grain texture with horizontal V-grooves every 3″ on both the exterior and interior face sheets. Model CHT-832 has a 20-gauge flush-smooth surface on the exterior face sheet and a 26-gauge wood-grain texture with V-grooves on the interior.

3 Tongue & Groove Section Joints

Tight sealing tongue-and-groove section joints add wind resistance and strength, prevent air and water infiltration, and provide a full 1-3/4” thermal break to prevent temperature transmission.

4 Bottom Weatherseal

Full-length vinyl astragal retainer and flexible U-shaped bottom weatherseal provide a tight seal at the floor to resist rain and snow and absorb the shock of repeated closing.

5 Steel End Stiles

End stiles are formed from 16-gauge galvanized steel and feature vinyl end caps to create a thermal break

6 Smooth Operation

Full-floating ten ball bearing rollers in case-hardened steel races, mounted to fit the slope of the track, assure smooth, easy, and reliable operation.

7 Intermediate Reinforcing

Full-length 16-gauge steel back-up plates, inserted prior to foaming, ensure solid attachment of all hardware; also, pre-drilling assures proper positioning.

8 Heavy-Duty Hinges

14-gauge, hot-dipped galvanized steel hinges provide added strength,
durability, and reliable performance.



Tongue-and-groove construction With full-length vinyl top and bottom caps eliminate metal-to-metal Contact and provide energy efficient thermal breaks that limit transfer of heat and cold – a major advantage where conditioned air or controlled temperatures are important.


A full-length, one-piece vinyl U-shaped weather strip seals to irregular or unlevel floors, prevents infiltration of air, rain, or snow, and reduces impact shock when the door is closed against concrete flooring.


Flexible flap seals the top of the door against the header to seal out air filtration. Seal extends a full 2″ past the front of the door for maximum efficiency.


Interior and exterior steel is rust-proofed with hot-dipped galvanizing and pre-painted inside and out with an epoxy primer and an enamel top coat of white, brown, almond, sandstone, hunter green, grey, and bronze. (The interior side is available in white only.)


Attractive and practical, the 25″ X 12″ insulated 1/2″ tempered glass window inserts provide superior double-glazed insulation. Seal-tight frames and a new anti-condensation system ensure effective sealing and a bright, clear view. Windows are attached from the inside for easy installation and maximum security.
