The infill panels
The infill panels transform the lattice into a closed structure. The type of infill material used is determined by the purpose of the wall and by the choice of locally available materials.
Choosing the right infill panel. The characteristics of the infill material will depend on the specific building requirements including:
- Thermal insulation
- Acoustic insulation
- Fire resistance
- Ability to accommodate conduits
Options for infill panels:
- Mineral wool
- Cellular glass
- Fibre cement board
The most commonly used material for the infill panels is polystyrene. Polystyrene offers significant advantages in terms of design, production and on-site handling.
These advantages are:
- No cold bridges because the polystyrene acts as the shuttering
- Maximum flexibility for design purposes
- Extremely light and easy to handle on site
- Easy accommodation of plumbing and electrical conduits
Depending on the type of material used, infill panels can have straight edges or edges with tongue and groove for better interlocking.
