Currently, an increasing emphasis is being placed on the properties of walling systems and efforts are evidently being made to improve the aesthetic look of structures. Vented facade systems with bonded joints are a viable option. Nowadays, the vast majority of such facades utilise mechanical joints. However, facades with bonded joints are more than simply a convenient alternative. The following article, where the potential use of bonded joints in practice is investigated via experimental measurements, deals with this technology in more detail. The presented results are taken from a series of tests which conform to the requirements of relevant technical standards, particularly with regard to the test method. This article deals with the issues connected with testing the most critical element in the whole system – the bonded joint. For this purpose, “Cetris” cement-bonded particleboard was selected for use as cladding material, and a substructure made from aluminium alloy was chosen. Five types of adhesive were selected in order to find the most suitable bonding material. During the testing procedures, the suitability of the selected adhesives for the chosen combination of materials was tested, as was the assumption that the use of the most expensive sealant does not always provide the best results.

Structural design of the staircase is a separate issue in the design and realization of residential buildings. The design needs to be addressed in terms of static, fire safety, layout requirements and in the case of wood-based apartment buildings, also in terms of acoustics. The paper deals with the design of the staircase in terms of all the above mentioned factors. In addressing this issue, emphasis is placed not only on the design of the staircase, but also on the construction itself. The author of the solution focused precisely on the area of the prefabrication in the construction solution. The staircase is designed as a separate space cell, which is produced as part of the pre-production preparation of the building, and is then installed as a finished product. This issue is addressed within the MPO TRIO FV10075 “New technology multi-storey energy efficient buildings made of glued sandwich panels with the possibility of foundation based ground screws using the technology of prefabricated housing units” project and the staircase solution is an integral part of this project.
