Simple door

Information

Overview

The Door model models

  • the conductive heat transfer through the door with a U-Value is set to 1.8 W/(m²K) (EnEV2009)
  • the radiative heat transfer on both sides

Assumptions

  • Constant U-value.

References/ U-values special doors

  • Doors of wood or plastic 40 mm: 2,2 W/(m²K)
  • Doors of wood 60 mm: 1,7 W/(m²K)
  • Doors of wood with glass:
  • 7 mm wired glass: 4,5 W/(m²K)
  • 20 mm insulated glass: 2,8 W/(m²K)

- Doors with a frame of light metal and with glass:

  • 7 mm wired glass: 5,5 W/(m²K)
  • 20 mm insulated glass: 3,5 W/(m²K)

- Doors of wood or plastic for new building (standard construction): 1,6 W/(m²K)

- insulated doors of wood or plastic with triplex glass: 0,7 W/(m²K)
