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. 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. 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.
