CLT TECHNOLOGY

“WOOD IS NEW CONCRETE”

The world is constantly changing, and so are building materials and their use. There is already a culture of wood architecture in our western neighboring countries, as these countries are rich in this raw material. Austria, Germany and Switzerland are just a few of the countries where you can find wonderful chalets. People here are receptive to new things. Their aim was to speed up and simplify traditional timber architecture. For this reason, Austrian engineers were looking for a fast, precise, true-to-scale construction solution, which they found in 2000.

This technology is now known as CLT, the Hungarian equivalent of cross-laminated timber. Due to the simplicity of the construction, they were able to reduce the actual construction time. Less human resources (technicians, manual workers) are needed for the construction process than in case of a traditional brick building. This is particularly important nowadays, as almost all industries suffer from labor shortages. Professionals are in short supply, and the number of manual workers to serve them is steadily declining. This is one of the reasons why it has become necessary to develop a technology that can deliver high quality work efficiently and quickly with a small number of workers.

CLT is the perfect solution for this purpose!

CLT is a wood panel laminated by cross gluing and pressing.

The layers are planed lamellas of spruce, silver fir, Douglas fir or larch, glued with resin. In Europe, spruce is the most widely used species.

Timber is kiln-dried material with a moisture content of 12 +/- 2%. This is first lengthened to the desired extent, then planed. This is followed by cross-laminating, where the layers are always perpendicular to each other and are odd in number.

SOME OF THE BENEFITS OF CLT PANEL BUILDING

• building material from natural, sustainable and responsibly managed forests,
• providing a healthy and pleasant living environment,
• short construction time, the building is dry immediately after completion,
• can be prefabricated.
• surfaces of the required quality,
• can be built quickly and easily in any season,
• has excellent structural properties,
• perfect shape and size accuracy
• easy to shape and assemble with high precision,
• can be installed in hard-to-reach places,
• has good thermal and sound insulation properties,
• excellent and scalable fire resistance,
• perfectly airtight,
• due to its heat storage capacity, the internal temperature follows dampened the fluctuations in the external temperature,
• earthquake resistant,
• excellent moisture regulator,
• smaller wall thicknesses allow for larger open interior spaces and up to 10% more living space,
• suitable for multi-storey construction and multiple relocation.

TECHNICAL DATA

• thickness: 60-340 mm,
• width: max. 3000 mm,
• length: max. 16000 mm,
• the panel weighs 470 kg/m3.

All cut-outs, holes and millings in the panels are made in the factory by the manufacturer using a CNC machine unit according to the specified plans.
When we mention CLT technology, we are not talking about a lightweight house. It is much stronger and heavier, but five times lighter than concrete. It has excellent heat retention capacity even when the heating is turned off.
