Thanks to the excellent properties of the VELOX building systems, the construction of passive houses is possible.
When designing the building and developing the detailed construction solutions, the need for consistently low energy consumption must be taken into account.

What is the purpose of VELOX
For low-energy and passive buildings
VELOX is an innovative construction technology developed in Austria, designed for low-energy and passive buildings. Using woodchip-cement boards, VELOX structures provide superior thermal and sound insulation, fire resistance, and rapid construction speed—all while maintaining a low carbon footprint.
VELOX buildings create the perfect blend of thermal insulation and heat accumulation to create a comfortable living environment. Due to the excellent thermal resistance of the external walls and the heat accumulation of concrete cores, rooms remain pleasantly cool throughout the summer and retain necessary heat in winter.
The ability to absorb external noise interference and high fire protection, together with ideal thermal characteristics creates a comfortable living space.
The feeling of thermal comfort occurs when:
• The thermometer in a room shows 18 to 24°C
• The temperature difference between the inside of the perimeter wall and the room temperature is lower than 3°C
The VELOX building system meets these requirements with minimum consumption of thermal energy.
Installation of the VELOX building system is simple and accurate, easy to handle (only 20% of the total weight of the building is handmade), and requires minimal use of machinery. Construction is also possible at temperatures down to -5°C. Speed is one of the most important factors when evaluating the benefits of VELOX so that the final result of its use really pays off.
Example Schedule: Building a house with a usable attic space.
- First day: Finished building; a concreted front row bearing and interior walls.
- First week: Complete assembly of load-bearing walls and ceiling of the first floor, including the reinforcement and concreting.
- 3 to 4 week: Finished rough construction with VELOX and roof covered.
- 5th week: Continue further construction work on the completion of the building, similar to that of all building systems.
VELOX building system offers a significant return on investment – not only during the construction due to low transport costs, minimal storage space, the need for fewer workers and plaster and building material savings due to accuracy – but also in the finished buildings, where there is a significant saving on heating costs.
The walls of a VELOX building achieve high thermal resistance even at a thickness of 30cm, which increases the usable construction area.
- For 1m² walls you only need 2 boards of VELOX
- 2 boards of VELOX replace 60 bricks or 10 concrete blocks
- 100m² of built up area (1 detached house, ground floor and attic) = 21t = 1 lorry load
- Brick and block Standard wall materials = 84t = 4 lorry loads
VELOX boards can be processed like wood – cut, drilled, nailed, routed and don’t require screw anchors.
Houses built using VELOX technology can be original in their design because this building system permits the construction of ideas without any restrictions. Architect and designer can fully use their imagination when working with VELOX.
Technical and advisory service suppliers of VELOX building systems meet all requirements, including the provision of project documentation, technical supervision, staff training, implementation of construction site, or the delivery of “turnkey” builds.
VELOX Building system satisfies:
- Designers: Variability of use and functionality
- Investors: Economy, efficiency and cost structures
- Builders: Speed and precision construction of buildings
- End user: Low operating costs and ease of ecological housing.
Unique features of the VELOX system are a combination of thermal insulation materials and concrete.
Wall construction consists of permanently integrated VELOX formwork panels coupled with polystyrene foam, which is filled with concrete.
- Installation of formwork and pouring concrete is done on site.
- VELOX boards and foam polystyrene provides excellent thermal and sound insulation. concrete provides structural strength and thermal accumulation.
- The result is a monolithic sandwich with excellent conditions for living.
The basis of ecologically produced VELOX boards are natural materials – wood chips (89%), which are associated with cement to ensure consistency and strength are complemented with a solution of water glass, which increases the resistance of the boards against moisture, rot and rodents.
Concrete buildings are stable and have a long life, so the quality of the house can appreciate over generations.
There are other companies that offer systems for building houses, but none offer the unique range of benefits that VELOX has.
