Protection from mould and heat loss

The air­proof­ing lay­er pro­tects the in­su­la­tion from mois­ture and con­dens­a­tion from the in­side, en­sures that the in­su­la­tion works ef­fect­ively and provides a healthy in­door liv­ing en­vir­on­ment.

The thermal insulation separates the indoor from the outdoor climate. The temperature difference between the two climates attempts to become equalised through the flow of air. This means in winter the warm air from the building transfers through the structural elements to the outside. The airproofing layer prevents this air flow, the so-called convection, and therefore the loss of hot air to the outside.

If indoor air were to flow unrestricted through the thermal insulation, it would increasingly become cooler the farther it penetrates towards the outside until it finally emerges as condensation. Condensation may cause considerable damage to the building and its components. Load-bearing structural elements may rot and lose their strength.

Similarly, moisture also promotes the development of harmful mildew and mould.

A vapour retarding and airproofing layer on the inside of the thermal insulation helps to avoid such structural damage.

Saving energy

Air­tight struc­tures are en­ergy ef­fi­cient. They en­sure that heat in­su­la­tion func­tions op­tim­ally. This re­duces heat­ing costs and CO2 emis­sions, pro­tect­ing the cli­mate and your wal­let alike.

Bauschaden vermeiden

Prevent structural damage

There is a risk of damage to structures as a result of mould and rot if moist indoor air in winter penetrates the thermal insulation structure and large amounts of condensation are produced. Airtight structures help prevent this.

Healthy living spaces

Air sealing protects against mould, helps prevent dry air in the winter and keeps living spaces cool longer in the summer.
