IRSA Lackfabrik Irmgard Sallinger GmbH
IRSA is a member of DGNB - The German Sustainable Building Council (DGNB – Deutsche Gesellschaft für Nachhaltiges Bauen e.V.)
Overview of the DGNB.....
The DGNB was founded in 2007 by 16 initiators from various subject areas within the construction and real-estate sectors. The aim was to promote sustainable and economically efficient building even more strongly in future. The reaction to the founding of the DGNB was extremely positive. By the beginning of 2008 121 organizations had already joined the DGNB. Today the association has more than 1,100 members throughout the entire world, because we see ourselves as a German and international knowledge platform. Our vision for 2050: a sustainably built and liveable future. There are more than 500 experts who support us on a volunteer basis: architects, investors, project developers, scientists, builders and other specialists from the construction and real-estate sectors
Sustainability as the DGNB understands it.
Sustainability is more than just a word for the DGNB: we understand sustainability as the obligation of the whole of society to shoulder responsibility for current problems such as climatic change and resource depletion instead of merely leaving them for future generations to deal with.
Sustainable building can make a crucial contribution to this: according to the German Ministry for the Environment, buildings account for roughly one third of the resources consumed in Germany and a similar proportion of carbon emissions and waste. Among other things, these figures can be systematically reduced through sustainable building.
We want to make the general public aware that a sustainable form of building is necessary and, above all, is possible. We attain this goal with a systematic transfer of know-how through events, media and the training of construction professionals to turn them into sustainability experts.
In our committees, scientists and practical workers cooperate closely in an interdisciplinary manner. Anyone can bring in their knowledge and supplement it with the technical expertise of others.

In order for the parquet flooring work to be carried out successfully, we would like to point out the following specific features, which lie outside the area of responsibility assumed by the company laying the parquet flooring:
Renovating old flooring and laying new wooden flooring:
What do you need to pay attention to before starting the parquet flooring work?
You have decided to renovate your wooden floor or to buy a new one. A clever decision, which not only serves to increase the beauty of your residence, but also the value.
The following information serves to improve the implementation of parquet flooring work.
Let us know if you can see any difficulties with regard to the following technical anomalies that could possibly occur, and/or we will inform you what needs particular attention, before, during and after the parquet flooring work:
1. Old wax on old flooring which is to be sealed after sanding
For example old flooring can be coated to varying degrees with old wax. In this instance larger or smaller amounts of wax deposits remain in the joints or other cavities in the flooring even after the most thorough sanding. Due to the fact that wax remains and sealing products for parquet flooring basically do not agree with each other, adhesive problems can occur according to each individual situation and the degree of wax coating.
2. Silicon deposits
The same is also true for so-called silicon deposits, which can be existent on site in old or new flooring or can be introduced without any help on the part of the sealer. Such a case is, in practice, exceedingly rare and unavoidable on the part of the parquet floor layer, since he is unable to recognize the invisible silicon in advance. Silicon can be found e.g. in several technical products such as assembly foam, sealing compounds, wall-paper stripper and even in the smallest traces can cause matt spots or contraction in the parquet sealing later.
Your parquet flooring sealer can not be held responsible for this. In this instance the customer has the choice to either accept the flaws in the sealant or to have another sanding down of the sealant as well as a new floor sealing carried out at his own expense.
3. Safety and environmental protection are also very important topics:
The regular parquet flooring sealants contain solvents which primarily evaporate during the sealing process and the drying of the sealant layer. During this period open flame, exposed light, welding, smoking etc are strictly prohibited in the hazard area. It is better to make use of water-based varnishes or oils and by doing so you will be preserving mankind and the environment.
4. Odour development in the first days after the surface treatment.
Even when using ecologically compatible water-based varnishes or solvent free oils, there is still a particular product -specific inherent smell noticeable in the first few days after application. Modern water-based varnishes contain minor amounts of solvent (see Giscode), which are emitted into the ambient atmosphere during and after the hardening of the varnish. Fatty-acid by products are produced by oxidative drying oils and these can be smelt already even in the lowest concentrations.
Hence it is important to pay attention to airing the room sufficiently in the initial days after the surface treatment so that the room's air pollution can quickly fade away.
5. Good ventilation is important – particularly during the heating period
You should always pay attention to regular good ventilation and only maintain after the freshly applied varnish or impregnating system is completely dried out. Air that is too dry is also questionable from a physiological standpoint: one's well-being is impaired in air that is too dry, as it dries out the mucous membranes and promotes conditions favourable for infectious diseases.
6. How to avoid visual disturbances that can arise later in parquet flooring e.g. joints between the wood sections:
Wood is a natural product and adapts itself to the ambient room air. If the indoor climate is kept constant then there would be no (unequal/differing) joints. Due to the so-called side and/or edge gluing, e.g. with water-based varnishes (causes with other factors a possible uneven joint formation), ugly joints can appear during/after the heating period (the wood shrinks) especially in wood that works more than others (e.g. beech, maple) if there is insufficient humidity.
Therefore we advise: Ensure a healthy room temperature (ideally 20°C and 55% humidity) by using e.g. a humidifier. Read about the relevant care instructions to this topic issued by IRSA under http://www.irsa.de/download. We would also be happy to send you these in printed form.
7. Restoring multi-layered parquet – unsticking the covering lamination
It is well-known that problems arise with multi-layered parquet with regard to the gluing and/or the laminate pressing process of the covering lamination. Due to the ever changing humidity of the wood during the course of the year constant pressure builds up between the covering lamination and the middle/counteracting layer, which have t demands on the gluing.
During the course of the restoration additional strain can arise due to sanding, or as a result of swelling pressure or nominal tensile stress in the varnish film. This can then result in a partial or complete unsticking of the covering laminate, which in turn can lead to raised corners and edges, concave dishing or loose lying covering lamination.
8. Correct care and cleaning
Finally at this point we point out the necessity of regular and co-ordinated care of your sealed, oiled or oiled/waxed parquet flooring. Relevant care instructions can be found enclosed under
The instructions and specifications in this letter are in accordance to the best of our knowledge according to the current state of technology. They are solely for information purposes and as a non-binding guideline. Any liability claims can not be derived from them. In cases of doubt relevant test surface treatments should be carried out. The recommendations in the technical data sheets and similar technical information issued by IRSA are to be heeded to with overriding precedence.
