Airtightness is the key to lifelong protection of timber components. Being organic material, timber frames can be the perfect food source for the growth of mould when moisture, oxygen and warm temperatures are present together. It is important to let the timber frames dry and block any water vapour transfer from the inner room to the construction.

In timber walls, the insulation is filled between the timber studs, or between studs and counter battens. Apart from the insulated load bearing construction, the outside insulation layer can be produced by either a compound insulation system or a rear ventilated façade insulation. It is relevant and essential that the airtight layer be fixed on the heated side of the construction.
