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

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.
 

• 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. The slat has an R-value of 8.0 (U-factor of 0.125) as calculated using the ASHRAE Handbook of Fundamentals.

• 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 22 gauge 300 series stainless steel with #4 finish and #18 B&S gauge aluminum with mill, clear or color anodized finish.

• 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.
