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 2 Cavity wall with lightweight masonry leaf
