Energetic refurbishment - interior insulation

Interior insulation

In principle, insulation can take two forms, namely exterior and/or interior insulation. While exterior insulation is the norm for new buildings, older buildings – especially those with a high-quality or even listed façade – cannot be insulated from the outside.

So-called “capillary-active” interior insulation is more robust and much easier to install than conventional interior insulation, because it does not require an interior film as a vapour barrier. Since 2009, iQ-Therm has been the benchmark for capillary-active interior insulation, combining two highly specialised materials into a perfect system in a simple yet ingenious way.

Hygrothermic calculations with the iQ-Lator

Realistic, clear and simple

Internal insulation has a particular influence on the physical behaviour of an existing construction. Particular attention must be paid to water vapour diffusion from the inside to the outside with possible condensation on the former inner surface of the building component and the limited drying potential of the outer wall after exposure to driving rain. Hygrothermal simulation calculations with coupled heat-moisture transport are recommended in order to install interior insulation safely from a building physics point of view. Refer to WTA Code of Practice 6-4 for more information. These hygrothermal calculations can be generated in a clear, simple and realistic format with iQ-Lator. With the help of the results, problematic wall structures can be identified and it can be estimated whether and how installing interior insulation will improve a construction in terms of building physics.
