U-value calculation examples

Example construction build-ups that can also be found in the U-value calculator.

Below example constructions can be seen which can also be found in the U-value calculator.
Example 1

Timber frame wall with brick cladding

The wall consists of the following layers

    - 120 mm brick cladding (thermal conductivity 0,77 W/mK)
    - 50 mm ventilated cavity (thermal conductivity 0,18 m2K/W)
    - 12,5 mm OSB board (thermal conductivity 0,13 W/mK)
    - mineral wool thermal insulation (thermal conductivity 0,037 W/mK)
      between 38 x 140 mm timber studs with a spacing of 600 mm
      (thermal conductivity 0,12 W/mK)
    - 12,5 mm gypsum plasterboard (thermal conductivity 0,21 W/mK)     
Example construction
