Insulation for Timber Frame Wall
For illustrative purposes only
U-value Calculator
Start your U-value calculation >An increasingly popular way of constructing new-build dwellings is to use a timber framed construction rather than traditional masonry cavity wall construction. Building with timber framed construction can offer a number of advantages and benefits over building with a more traditional form of construction, such as lighter weight and a higher speed of construction.
In a timber-framed wall, insulation is typically installed between the studs. This insulation can be glass mineral wool (Isover Timber Frame Roll or Batt can be considered) or PIR.
Depending on U-value requirements, there may be additional insulation required. This can be placed outside the sheathing board (i.e. within the external wall cavity); products such as Isover Polterm Max Plus can be considered.
