In­su­la­tion helps save en­ergy, avoid dam­age to build­ings and de­liv­ers a healthy in­door liv­ing en­vir­on­ment. To en­sure this works re­li­ably and ef­fi­ciently over the long run, one design as­pect is es­pe­cially crit­ic­al in terms of build­ing phys­ics: The thermal in­su­la­tion must be pro­tec­ted on both sides.

The ideal structure is 3-ply

  • An air­proof­ing lay­er such as a va­pour re­tarder is loc­ated on the side of the in­su­la­tion fa­cing the room
  • The thermal in­su­la­tion ma­ter­i­al is in the middle.
  • On the ex­ter­i­or side, a wind bar­ri­er such as an un­der­lay or wall lin­ing mem­brane cov­ers the in­su­la­tion

This design en­sures that weath­er, con­dens­a­tion, mould and air flow do not neg­at­ively af­fect the per­form­ance of the build­ing com­pon­ent or even cause struc­tur­al dam­age.



Why airtight?

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.

Intelligent air sealing

Struc­tur­al dam­age is caused by ex­cess­ive mois­ture. In­tel­li­gent air seal­ing mem­branes of­fer sig­ni­fic­antly high­er pro­tec­tion for struc­tur­al ele­ments than con­ven­tion­al mem­branes.

Why windproof?

The windproofing layer protects the thermal insulation from rain, snow and wind from the outside. It also ensures that the insulation will not be permeated by cold air and hence can fully unfold its effectiveness.




Moisture-activated windproofing

New, mois­ture-ac­tiv­ated mem­branes with a non-por­ous, mono­lith­ic func­tion film of­fer sig­ni­fic­antly high­er pro­tec­tion levels than con­ven­tion­al mi­cro­por­ous mem­branes.
