Benefits > Healthy building
Breathability is at the core of what makes a building healthy.
Often referred to as ‘permeability’ or ‘vapour open construction’, this core functionality of the building fabric is its ability to deal with the negative effects of moisture in a natural way.
Fabric first approach
Buildings with a ‘fabric first ’approach’ are not afraid of moisture. They understand
how it works and deal with it in a natural way.
The internal side of a wall or roof incorporates a vapour control layer which limits
the amount of moisture that can enter the structure.
The external side is vapour open and ensures any moisture that does enter the
structure can naturally migrate to the outside and evaporate away.
In addition to this fabric balance, the use of wood fibre ensures that any moisture in the structure can be stored at source and then migrated to the outside through natural processes.
