Increasing energy efficiency through interior insulation systems

Written by esba

As an alternative to the conventionally used interior insulation with a vapour barrier, diffusion-open, capillary-active insulation is becoming increasingly popular on the market. Such materials transport moisture back capillary and thus contribute to regulating the moisture balance of a construction. They reduce the risk of moisture-related damage.

To supplement the existing material parameters, a new laboratory test was developed that can be used to analyse the moisture behaviour of capillary-active interior insulation materials more reliably than with the usual measurement methods.

About the author


The European Straw Building Association is an independent European association, devoid of any profit making motive. The object of the Association is to promote and develop the use of straw, as a sustainable way of building in all the senses of the term “sustainable”: renewable, ecological, healthy, energy and climate efficient, social and economic.
The Association is a federation composed of organisations and people particularly concerned with the use of straw in buildings.
