Debate on the possibilities of multi-storey wooden buildings in the Czech Republic

/0 Comments/in /by

The Jaroslav Fragner Gallery hosted the exhibition White Arkitekter: A HEART OF WOOD until mid-March. It was the first exhibition of one of the most important Swedish architectural studios in the Czech Republic and featured the innovative use of CLT panels for high-rise buildings. The internationally active White Arkitekter office is dedicated to environmentally and socially sustainable architecture using wood as an important renewable material. In 2016, the studio designed a 20-storey building in Skellefteå, Sweden, which is one of the tallest wooden high-rise buildings in the world.

The accompanying programme included an expert debate on the possibilities, technologies and materials for multi-storey buildings in the country. One of the panelists was the director of the Timber Research Institute, Mrs. Jitka Beránková.

You can watch a recording of the debate on YouTube here.

RotaFloor – new options for testing floors and tiles with certification

/0 Comments/in /by

The Timber Research Institute has developed and commissioned a new testing facility that brings the possibility of testing not only traditional wood-based materials, but especially tiles, whether ceramic, concrete, terrazzo or large-format tiles.

However, this area is not as far removed from the remit of the Timber Research Institute as it might at first appear. One of the main sources of problems in modern timber buildings is the watertightness of bathrooms and other areas traditionally fitted with ceramic or similar tiles. Understanding the properties and durability of these surfaces should also lead to new research tasks in this field in the future.

The device is unique because it was developed in the Czech Republic on the basis of available and standardized information, in close cooperation with the Silicate Association and its leading expert Dr. Eduard Justa, WOODEXPERT s.r.o. and GIS Engineering. There are only units of similar equipment in Europe.

RotaFloor, as the test facility of the Timber Research Institute was named, enables accredited testing of tiles and other floor constructions according to several foreign standards.

The principle of testing is the movement of specific castors loaded with standardised forces over the floor surface. During the development process, it was necessary to solve the issues of precise loading, speed control or converting the requirements of the American standard into the metric system.

The equipment is now fully operational, has successfully passed the accreditation process and is being used, among other things, to prepare for planned research on the long-term waterproofing of bathroom floors in wooden buildings.

In the new year, the European ETA directly with the Timber Research Institute

/0 Comments/in /by

The Timber Research Institute has newly been authorised to issue ETA documents for the assessment of construction products in the woodworking industry with sales in the European Union markets.

Direct cooperation with the Timber Research Institute therefore enables manufacturers to draw up declarations of performance and obtain the CE mark for their products.

Auditors can assess and also carry out regular surveillance of the production management system in system 1, 2+ according to Regulation (EU) No 305/2011 of the European Parliament and of the Council.

Research on airtightness of wooden buildings published

/0 Comments/in /by

For several years, the Timber Research Institute, together with experts from the CTU and ČZU, has been collecting and evaluating data from measurements of the airtightness of buildings. This unique statistical data set was compiled, analysed and published in the prestigious scientific journal Building and Environment, issue 194. The use of the Blower door diagnostic method, which the Timber Research Institute carries out in an accredited mode, has been shown to contribute significantly to improving the performance of timber buildings. Therefore, one of the indirect results of the research is the confirmation of the well-known truth that prevention (using scientific knowledge) is better than subsequent complex and costly repair.

Reference to the article in the publication Building and Environment (ENG):

Factors influencing envelope airtightness of lightweight timber-frame houses built in the Czech Republic in the period of 2006-2019: https://authors.elsevier.com/a/1cceM1HudN4BuQ

This research was supported by the Grant Agency of the Faculty of Civil Engineering, CTU in Prague (projects SGS19/143/OHK1/3T/11 and SGS20/153/OHK1/3T/11) and the Grant Agency of the Timber Research and Development Institute in Prague (project TIP/IGA/1/2019).

Certification of ADMD members more rigorously supervised by the Timber Research Institute

/0 Comments/in /by

The certification process of ADMD (Association of Prefabricated House Contractors) members has long been carried out by the Timber Research Institute. This year, the quality requirements for some of the construction processes of houses according to the DNK document have been increased. Engineers at the Timber Research Institute have drafted modifications to the certification document and will continue to monitor compliance with the requirements for the manufacture and assembly of timber buildings.
