Better air with interior insulation
Our approach to the internal insulation:

The cause: Visible facades not isolated
Insufficient insulation of the exterior walls leads to cooling of the interior and moisture being attracted to the surface of the walls. The consequences are an uncomfortable indoor environment, a risk of mould contamination and high energy consumption when trying to raise room temperature.

Our 1st step: Preparation
Initially we carefully clean the surface, removing wallpaper and paint. We eliminate any mould infestation professionally.

Our 2nd step: Installing the interior insulation
We place a special adhesive mortar to bind the high diffusion insulation plates to the wall surface.

Our 3rd step: Refinement
Finally, we revise the surface with a special putty in which is incorporated a reinforcement fabric. With the optional final skim we provide a smooth and even wall surface. This surface can be painted to taste.

In the last 25 years the ISOTEC Group has successfully sealed more than 100.000 properties in Germany, Austria and Switzerland.
The owner of this family home commissioned ISOTEC to carry out a comprehensive renovation. The ISOTEC Interior Insulation, particularly for the exterior façades that comprised elaborate designs which warrant preservation, can also be a possible measure to prevent condensation-related mould growth in living areas.
Humidity and mould-inhibiting regulation
Thanks to the capillary conductivity of our ISOTEC Interior Insulation, there is no need for a vapour barrier. The interior insulation absorbs excess humidity from the ambient air and releases it when the air humidity falls again.

Insulated walls have a positive effect on our well-being
The non-insulated walls not only negatively impact the comfort of the interior environment, but also reduce the ambient temperature and surface temperature of the walls, which favors the growth of mould. A subsequent insulation with our ISOTEC Interior Insulation provides a pleasant interior environment, prevents mold formation and maintains ambient temperature in isolated spaces.
Interior insulation isn’t only a good option for listed buildings but for all buildings which have a façade worth protecting
In addition, insulation carried out from the inside normally requires less work and can be done at a lower cost, because it isn’t always necessary to insulate the entire façade. If, for example, there is only damp and mould damage in some of the rooms, then only those affected rooms need to be renovated. Another important advantage when interior sealing and renovating work is done from the inside, is that both the garden and any adjacent structures such as a garage remain intact. Although in terms of the building physics external renovation and sealing is your best option, your house will be equally protected from damp if you do choose to insulate from the inside. We usually apply the interior insulation in the course of removing the mould damage.
ISOTEC Quality
At ISOTEC we only use construction materials that have been verified in real world settings and comply with all the official requirements and regulations. This also applies to the structural-physical properties of the ISOTEC Interior Insulation system, which has been proven extensively both scientifically and practically to provide protection against moisture, mould contamination and for its thermo insulating properties. All renovation work on your home is carried out by our highly trained and capable staff.
