Modern solutions made of structural wood

At TimberTech, we work with the full range of modern structural wood building materials – the same ones used in Germany, Austria, Switzerland and Scandinavia.
These materials are high-tech, factory-produced, with guaranteed strength and insulation properties.
They are used for both residential and public buildings, as well as for multi-storey complexes, hotels and industrial sites all over the world.

CLT - Cross Laminated Timber

CLT is a softwood material made of several cross-laminated layers (usually 3, 5, 7 or 9) bonded with high-tech formaldehyde-free adhesives. This cross-laminated structure gives the material exceptional strength, stability and earthquake resistance – comparable to that of concrete, but at a much lower weight.

CLT is factory-produced with a sanded surface and precise dimensions.

CLT panels – cross-laminated timber for walls and floors

Advantages:

Exceptional static stability and earthquake safety.
Fire resistance.
Excellent energy efficiency – wood is a natural insulator.
It does not require plastering or finishing work - an aesthetically finished material.

Over the past decade, CLT has become one of the most preferred building materials in Europe and around the world. Thanks to its strength, lightness and flexibility, it is used in the construction of single-family homes as well as in multi-storey buildings, hotels, public and industrial facilities. CLT panels are produced with computer-controlled machines, which guarantees millimetre-precision of every opening, corner and joint. This means that all elements arrive at the site completely ready for installation – without the need for adjustments or finishing work. CLT is not only a strong and durable material, but also much more environmentally friendly than traditional building solutions. It is made from renewable wood, which naturally captures and stores carbon dioxide from the atmosphere. Thus, any building built with CLT actually reduces its carbon footprint, because wood retains more carbon than is released during its production – unlike concrete and steel, which are some of the largest sources of carbon emissions. In addition, CLT offers a unique aesthetic effect – the natural texture and warmth of wood create coziness and comfort that can be difficult to achieve with inorganic materials.

Therefore, architects around the world are increasingly choosing CLT not only for its technical advantages, but also for its visual beauty and connection to nature.

Projects implemented with CLT:

"Quai de la Borde" - located along the Seine in the Paris suburb of Ris-Oranges, the complex includes 140 apartments distributed in five interconnected four-story buildings with a total area of 8,800 square meters. It was built with 1,800 m³ of CLT panels and completed in just 13 months - a third faster than usual. Its architecture combines a contemporary vision with traditional regional elements, demonstrating the advantages of wood as an alternative to concrete and brick in urban construction.

Single-family house in Žamberk, Czech Republic – low weight and high stability, which allow the implementation of a bold architectural concept on difficult terrain. The interior also emphasizes the qualities of CLT panels – their aesthetic finish eliminates the need for additional processing, while the exposed wooden surfaces create a warm and cozy atmosphere.

BSH – Glued Laminated Timber

BSH (from the German Brettschichtholz) consists of several lamellas glued together parallel to the fibers. The result is a material with exceptional strength and stability, which allows the implementation of large open spaces without the need for intermediate supports. It is used in sports halls, halls, bridges, public and industrial buildings.

Advantages:

Up to 80% lighter than reinforced concrete with the same load-bearing capacity.
Allows large openings and distances without intermediate supports.
It can be made in curved or straight shapes - suitable for arches, domes, roof structures.
It is characterized by high geometric accuracy and stability, without twisting or cracking.
It has an aesthetic vision – it often remains a visible element in the interior and architecture.

BSH is used for load-bearing structures - beams, columns, arches, roof trusses and frames of large spaces.

The material is ideal for sports halls, commercial and industrial halls, public buildings, bridges and modern homes. Thanks to its lightness and strength, it allows for architectural solutions that are impossible with concrete or steel without significantly higher costs. BSH is a major construction material in Central and Northern Europe, as well as in Canada, the USA and Australia. It is preferred not only for its durability and environmental friendliness, but also for its precise factory manufacturing, which reduces construction times and ensures high quality of each element. BSH is certified according to all European standards for strength, fire resistance and safety, making it perfectly suitable for large-scale architectural and engineering projects. Like CLT, BSH is a renewable, environmentally friendly material produced from sustainably managed forests. It retains the carbon absorbed by trees during their growth, thus reducing the carbon footprint of each building.

Using BSH instead of concrete or steel saves tons of harmful emissions and makes construction significantly more environmentally friendly.

Projects implemented with BSH:

Museum Louis Vuitton Foundation, Paris

One of the most impressive buildings constructed with BSH structures. Designed by world-renowned architect Frank Gehry, the museum is distinguished by its complex, sculptural form and 12 glass roofs supported by 222 uniquely curved beams made of multilayer wood (BSH).

These beams combine exceptional strength and flexibility, allowing the realization of architectural geometry impossible with traditional materials such as concrete or steel.

The project is a prime example of how structural wood can be used in modern high-tech engineering and art construction.

Bunjil Place, Melbourne, Australia - a multi-purpose cultural center with an impressive roof structure of 166 m³ of curved BSH beams. The architecture symbolizes the wings of the mythical Bunjil bird - protector of the people.
The project demonstrates how laminated timber structures can combine engineering precision, scale and artistic vision in contemporary urban construction.

KVH

KVH (Konstruktionsvollholz) is a solid structural timber made from carefully selected softwood, factory-dried, planed and profiled with millimetre precision. Thanks to its stability and easy processing, KVH is the standard in Germany, Austria and Switzerland for the construction of modern timber structures.

Advantages:

High strength and resistance to deformation
Precise dimensions and easy installation
Long-lasting and stable material
Ideal for passive and energy-efficient buildings

It is used for frame walls, roofs, floors and facade elements, as well as as an additional structure in CLT and BSH systems. It is suitable for single-family homes, superstructures, extensions and light load-bearing structures. It is produced from renewable wood and has a very low carbon footprint.

Thanks to its high precision and factory quality, it reduces waste and construction time.

LVL - Laminated Veneer Lumber

LVL is an engineered material made of multiple thin layers of veneer oriented in one direction and glued together under high pressure.

The result is an extremely strong, solid and durable product with high load-bearing capacity at minimal weight.

Advantages:

Stronger than reinforced concrete at significantly less mass
Excellent stability and torsion resistance
Precision and easy handling during installation
Suitable for highly loaded elements and long openings

LVL is used for beams, columns, roof and wall panels, as well as in combination with CLT and BSH in multi-storey buildings, bridges and industrial sites. Widely applicable in Scandinavia, Germany, Japan and the USA, where wooden structures are part of the standard for sustainable construction. It is produced from renewable wood and stores the carbon taken up by trees during their growth. Due to its high strength and efficient use of the material, LVL is one of the most sustainable solutions for modern construction.

Implemented projects with LVL:

Aalto University – SuomiAreena 2017 stage, Finland

The stage, designed by Aalto University, is constructed entirely from LVL elements.

The structure is modular and demountable, designed to be assembled and disassembled repeatedly without losing its structural integrity. The project shows how LVL can be used not only in buildings but also in public and temporary architectural structures where precision, aesthetics, and quick assembly are required. The material provides visual lightness and high load-bearing capacity, and its use in an outdoor setting demonstrates the durability of wood even in outdoor conditions.

BauBuche in interior design

The use of BauBuche in interior design, and especially in the design of staircases, allows for the creation of elegant and functional architectural accents. In this example, the staircase is built entirely from BauBuche Panel. The construction is cantilevered and bolted, without side supports, which creates a feeling of lightness and a “floating” shape in the space. The steps, 60 mm thick, are complemented by a BauBuche edge banding, so that the texture of the veneer layers remains visible both from the front and from above. The railings and handrails are also made of the same material and finished with natural oiling, which emphasizes the warm color and elegant shine of beech wood.

Kielsteg

Kielsteg is an innovative wooden building element created in Austria that combines exceptional lightness with high load-bearing capacity. It consists of two solid wooden skins (upper and lower), connected by internal “wave-shaped” plywood bridges, which form a hollow but extremely strong structure.

This technology allows distances of up to 27 meters to be covered without intermediate supports, making the system ideal for large open spaces.

Advantages:

Extremely light but durable material - high load capacity at minimal weight.
Allows for free architectural solutions and wide openings without columns.
Excellent thermal insulation and acoustic properties thanks to the hollow structure.
Quick installation and low dead weight, which reduces the need for heavy foundations.
Suitable for large roof systems - sports halls, commercial buildings, halls, public buildings.

Kielsteg was developed at the University of Graz (Austria) and is manufactured to strict quality and sustainability standards.
Each element is manufactured in the factory with computer precision, which ensures a perfect fit of all connections and a long service life. The material is entirely made of wood, without metal elements in the supporting part, which guarantees high fire resistance and environmental friendliness.
The system is actively used in Austria, Germany, Switzerland and Scandinavia, where timber construction is the leading standard. Due to its lightness and stability, Kielsteg is applied in roof and ceiling structures of large buildings, such as logistics centers, sports complexes and office buildings. It provides a natural look, excellent insulation and a minimal carbon footprint, making it a preferred choice for projects with a focus on sustainable construction and energy efficiency. Kielsteg is made from renewable softwood, and the material captures and retains the carbon accumulated during the growth of trees. Compared to concrete and steel, it requires significantly less energy to produce, making it one of the greenest construction systems on the market.
