Diky za odpovedi. Myslite si neco o tomhle?

Eh, sorry to say I didn't think about it!
All sounds excellent, apart from the glue they sell to join it FERMACELL Jointstik. (same problem with manufactures recommendation to join Ekodesky: Stay away from polyurethane!):
Recommendations to the consumer:
FERMACELL Jointstik.
The FERMACELL Jointstik contains diphenylmethane-4,4’-diisocyanate. This substance may irritate the mucuos membrane, skin and eyes. The MAK-list from 1993 classifies the substance to be sensitizing. The Austrian Institute of Construction Biology and Ecology can therefore not recommend the application of the FERMACELL Jointstik. Alternatively, the FERMACELL
Joint Filler can be applied. Constructions requiring the applications of FERMACELL Jointstik should be avoided.
Does the customer decide, however, to apply the Jointstik, a professional should be consulted. A sufficient aeration has to be provided. Please pay attention to information on hazards!

...But heres the many positive aspects of Fermacell:
-------
After full consideration of all the available information. The Austrian Institute of Construction Biology and Ecology (IBO) has awarded the IBO test mark to the above-named product. These products may be accordingly designated as “tested by the Austrian Institute of Construction Biology and Ecology”.

We at Energybuild were impressed enough with this product to use it in our test house. Unlike plasterboard, Fermacell is fixed in position with screws. The sheets are machine cut with precision edges so that jointing is accurate and precise. It is a self finished board which means there is no need for plastering as one would do with plasterboard. It can be painted directly which gives an excellent finish or if you want a pristine effect, a coat of extra smooth finishing may be applied with a squeegee tool in extra quick time by an unskilled person. We choose 8ft x 4ft boards which were a lot heavier than plasterboard and as a result were difficult to put up. But Fermacell can also be purchased in one man sheeting sizes that will overcome this problem. There was only one drawback we found with the construction method. Because there is no use of plaster, which is often a compensation leveller for bad workmanship, it is essential that your underneath construction work is good quality. Sometimes this can be difficult as softwoods purchased here in Ireland are not always up to quality because of storage facilities. Fermacell is much more expensive than plasterboard but when you allow for the fact of labour and cost savings on plastering then we reckon it is no more expensive. Overall, this product can only be described as a brilliant step forward and full credit must go to the inventors. We found that being able to approach and use a stud wall, for the purpose of hanging items on, as one would approach a solid wall was fantastic. The acoustics, from experience, are far superior and because the boards have impact resistance qualities, there is a far more solid feel about the house.

Introduction
FERMACELL has a very simple homogenous composition:
80% recycled gypsum and 20% cellulose fibres derived from recycled papers, mixed with water. In other words, it's a 100% recycled material. There are no additives or preservatives used whatsoever. The entire process is also fully recycling, which means that all by-products are fed back into the production cycle.
Sustainability Matters
FERMACELL'S manufacturing technique is unique.
Both FERMACELL and the process have been awarded the coveted Rosenheim Institute of Construction Biology and Ecology Certificate and the Low Emissions Product Eco Certificate. FERMACELL has also been defined as a 'Heathy Living' Building Material for allergy-free environments. FERMACELL'S commitment to sustainability focuses on a 'whole lifecycle' approach to environmental management.
