Examples

These are example constructions which can be loaded directly in the U and R value calculator. If you would like to include other examples, please email us or leave a message in our blog and we will try to incorporate them.

Example 1. Timber framed wall example

The construction consists of the following layers:

    - 102 mm brick outer leaf (thermal conductivity 0.77 W/mK)

    - 50 mm air cavity (resistance 0.18 m2K/W)

    - 9 mm timber-based sheathing (thermal conductivity 0.13 W/mK)

    - mineral wool quilt (thermal conductivity 0.04 W/mK) between 38 x 140 mm timber studs (thermal conductivity 0.12 W/mK)

      at 600 mm centres

    - 12.5 mm plasterboard (thermal conductivity 0.21 W/mK)
