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)
