Model ESD20

Thermiser® Insulated Rolling Service Doors are recommended for exterior openings where maintaining different temperatures on each side of the door is desirable.

Sizes: Standard construction for openings up to 30' wide x 30' high. Larger sizes available; consult factory.

Operation: Motors, chain, or hand-crank designs based on size, weight or frequency of operation.

Usage: Standard construction is up to 20 cycles per day with High Cycle Construction available for doors expected to be operated more than 20 cycles per day.

Thermiser Benefits: Energy Savings: Thermiser doors pay for themselves in 42 to 48 months, depending on the climatic zone.

  • Design Flexibility: Cornell doors are built to order to fit your opening size, operation and option preferences.
  • Insulation: Keeps buildings warm in winter, cool in summer. Closed cell urethane foam insulation provides the lowest thermal conductivity of any material commercially available.
  • Energy Savings: Upgrading to a Thermiser from a WeatherGard pays for itself in 42 to 48 months, depending on climatic zone.

Perimeter Weathering: Thermiser weatherproofing at bottom bar, guides, and lintel/door header cuts air infiltration rate by 90%. Urethane foam-filled bottom bar and compressible astragal provide seal at sill. Replaceable vinyl weather-stripping at guides forms weather seal along curtain exterior. Lintel mounted nylon brush impedes air flow around coil.

Materials and Finishes: Exterior and interior slats are ASTM A 653 galvanized steel with exclusive GalvaNex™ finish in light gray, SpectraShield® powder coating finish optional. Exterior skin is available in 24, 22, 20 & 18 gauge with combination exterior and interior slats being - 24/24, 22/24, 20/24, 18/24 and 22/22. Exterior and interior skins are also available in 24 gauge 300 series stainless steel with #4 finish and #18 B&S gauge aluminum with mill, clear or color anodized finish. For more information on materials and finishes.

Special Design Applications: Thermiser doors muffle unwanted sound in hospitals, schools, universities, and other institutional, commercial, and industrial buildings. The Thermiser's urethane foam-filled slats and perimeter seals tested at a 26 STC rating compared to a STC 19 for non-insulated doors.
