Good customer contact has been our greatest concern since the beginning. Good customer relationships and an open ear for their challenges are the reason for our solid growth and the development of parapets, balcony railings and parapets. In the future, we will continue to build on a close relationship with our customers – rather with the people who stand behind it and are just as enthusiastic about overtec as we are.
Overtec didn’t come about overnight. Founded in 1978, the focus was on the insulation material trade for two decades. Around 2000, my father brought a prefabricated nesting element onto the market, which is still in high demand today. A good decade later, I came to overtec.
My dream has always been to build a company with which we can inspire people and exceed their expectations. We want to set new standards with our parapet on the flat roof, the balcony railing and the parapet.
Every day we do our best to achieve exactly that. If it doesn’t happen at any time, I’m always open to hearing from you.
Sebastian Hilscher – overtec
The overtec team is divided into three locations: Production and an office in Attnang-Puchheim, another office in Vienna and a sales location in North Rhine-Westphalia. For our customers, we rely on personal proximity in sales to provide you with the best advice on parapets, balcony railings and parapets, while our back office is well digitally networked across our locations and handles your project professionally. We look forward to your inquiry and will do everything we can to exceed your expectations.
From there we grow into the European market with a focus on Germany. After a sales start in 2017, overtec Deutschland GmbH was founded in Munich in 2020. Different market conditions and normative regulations have meant that our product segment has been significantly influenced by both markets.
We are pleased to be working together with the best engineers and testing institutes in Austria and Germany to develop products for the construction industry. Two countries that are known worldwide in the construction industry for innovation, prefabrication and quality in construction.
It’s a constant cycle. In the floor plan. In reality, it is a spiral going upwards. First, people become enthusiastic about a product or service. Enthusiasm only occurs when existing expectations are exceeded. Our drive is to exceed expectations and thereby inspire people. If this happens regularly, the enthusiasm will eventually turn into a new expectation. A new standard has been set. And what happens then?
A cycle that always starts again. The only difference is that the foundation of expectations has now been shifted upwards.
We see ourselves as part of the progress in the construction industry and want to actively work to raise the standards in the industry.
We have aligned our company structure to this cycle. Inspire people, exceed expectations and set new standards became amaze people, exceed expectations and set new standards.
Through our innovations we want to exceed existing #expectations and thereby #inspire people. Until the
Expectations are permanently shifted upwards and innovations become a “new normal”. Then we have achieved our biggest goal: #setting new standards
The ecological footprint of our building products is recorded in the Environmental Product Decleration (EPD) and can be calculated for each product variant. We see it as our mission to make a difference towards sustainability. On the way there, the EPD represents the first important step: determining the emissions of our manufacturing process and then optimizing them in a targeted manner.
In order to give the topic more visibility, Sebastian Hilscher traveled with a cargo bike from Attnang-Puchheim to Frankfurt under the motto #WirAindRan to transport the last overtec element to the Timber Pioneer showcase project.
Cement causes 7% of global CO2 emissions. And therefore more than the entire aviation industry. What we can do in the construction industry? For example, recording the emissions of products to make product comparisons possible and using alternative building materials. Concrete will certainly not disappear, but certain components can be reduced or emissions can be reduced through optimizations in the recipe.
Overtec produces 63% fewer emissions compared to conventional concrete parapet elements. Due to the slim design of the overtec elements, fewer emissions are emitted when compared to components. What is not yet taken into account is the massive weight savings achieved by overtec, which means that less material has to be used indirectly for other components. For example, ISO baskets can be dimensioned more easily and ceiling thicknesses of cantilevered balcony elements can be reduced, even eliminating the need for support elements.
Sebastian Hilscher rides his cargo bike from Attnang Puchheim to Frankfurt to deliver the last overtec. The aim of the campaign is to set an example and to highlight the reduced-emission construction of the pioneering Timber Pioneer project by UBM Development and overtec. The components from overtec fit perfectly into the planning concept of a wooden hybrid building.
The shortage of skilled workers in construction continues to increase. In 2021, 67% of construction companies stated that the shortage of skilled workers has a significant impact on the development of their own company. In 2010 this figure was only 21%. In addition, 1/3 of all construction companies have problems integrating skilled workers into the company.
overtec is taking two options to counteract the shortage of skilled workers.
Initiatives based on our motto #handgripminimalest
+ Development of the OneBit screw. No more bit changing.
+ Connection of the overtec elements via connecting dowels. No use of electricity.
+ optimal marking of the accessory material and understandable instructions. No double handles.
The need for explanation is as minimal as possible to avoid misunderstandings.
While 400,000 apartments are needed per year in Germany to meet demand, only 245,000 were built in 2022. At the same time, most apartments were built in cities with fewer than 100,000 inhabitants. However, the greatest influx and demand is in large cities. Why is housing construction lagging behind in cities?
Available plots of land are often small and difficult to build on. Property boundaries, distances to neighboring buildings and maximum building heights pass on major tasks to planners and architects. Even in multi-story residential buildings, every cm often counts.
overtec is taking two options to counteract the shortage of living space.
If we looked at a building as a machine…
…, then we would install parts that are lighter, require less material and work more efficiently. In a gasoline engine, every component, right down to the last one, is energy-optimized. Why not in a building? overtec emits 63% fewer emissions during production and uses less energy over the entire life of the building.
The heat calculation shows: A concrete attic is also heated compared to overtec. In the illustration on the left, significantly more material is obviously required. The concrete element, which is around 4-8 times as thick, requires, in addition to the reinforcing iron, insulation that is placed around the component. The construction means that the attic is heated and cooled at the same time. When looking at the overtec element, it is noticeable that there is no internal insulation and that the heated and cooled elements are limited to the wall and the ceiling.
Voluntary in some countries, mandatory in others: the photovoltaic system on the roof. overtec increases the roof area by up to 35cm per linear meter. On a roof with a 100m surrounding attic, 35m2 more usable roof area is created. Depending on usage From 35m2 Our elements not only help with our responsibility to save energy, but also create more space for generating energy.
A chaotically sorted wood fiber mixture which is pressed and dried at 300 bar.
The mixture consists of fine wood particles, cement, water and hydration additives. While the wood particles serve as reinforcement and provide properties such as easy workability and high elasticity, the cement content ensures weather resistance and high compressive strength. The basic technical properties are anchored in EN 13986:2004+A1:2015, while the values actually achieved are usually significantly higher.

Overtec GmbH was founded in 1978 and initially established itself as a specialist in the trade of insulation materials. Over two decades, the company expanded its expertise in this area and consolidated its reputation as a reliable partner in the construction industry. In 1999, a decisive development marked a turning point in the company's history: Nikolaus Hilscher developed the first prefabricated building component, the overtec prefabricated shaft. This innovation significantly expanded the company's product portfolio and ushered in a new era of specialization and expansion.
Overtec is proud to be a family business that relies on tradition and innovation in equal measure. Nikolaus Hilscher led the company with vision and commitment for around 30 years before his son Sebastian Hilscher joined the company. Father and son jointly steered the fortunes of overtec for over a decade, constantly developing and modernizing the company. In recent years, Nikolaus Hilscher has increasingly focused on sales to long-standing customers, while Sebastian manages the operational business and shapes the next generation of company management.
Sebastian Hilscher, as CEO of overtec, has played a crucial role in the continuation and stabilization of the company since he took over all shares from his father Nikolaus Hilscher in 2019. Under his leadership, overtec successfully navigated the challenges of the COVID-19 pandemic as well as the turbulent times triggered by the Ukraine war. Sebastian Hilscher led the company through these crises with determination and strategic skill, focusing on overtec's adaptability and sustainability.

Overtec's values
Overtec sets itself ambitious goals to make its contribution to the transformation of the construction industry. With the aim of setting new standards, the company pursues innovative approaches to the development of modern construction methods. This also aims to save manual steps in the construction process, which actively counteracts the shortage of skilled workers. These efforts reflect overtec's commitment to innovation and environmental responsibility. A central aspect of their mission is to drive the sustainable transition in the construction industry by focusing on environmentally friendly practices and offering future-oriented solutions.
Overtec places great value on sustainability and uses innovative wood-cement panels in the manufacture of parapets, parapets, shaft elements and other building products. These materials emit up to 67% less CO2 than conventional versions, which significantly reduces the carbon footprint. By using these environmentally friendly alternatives, overtec underlines its commitment to climate protection and resource conservation. The EPD certificates issued to overtec can also be used for DGNB certification.
Overtec offers a wide range of products, including parapet elements, parapets and shaft elements, as well as other innovative solutions such as balcony partitions, planters, metal railings and privacy parapets. These products are specifically designed to optimize work processes and reduce the need for manual handling in order to counteract the shortage of skilled workers in the construction industry. Their well-thought-out design helps to increase efficiency on construction sites while enabling high-quality and sustainable construction projects. Overtec is thus positioning itself as a pioneer in providing solutions that meet the current challenges of the industry.
When manufacturing parapet and balustrade elements, overtec uses a wood-cement board that meets the requirements of EN13986. This standardized substrate is available in two fire protection qualities: A2 and B1. Depending on the customer's requirements, the appropriate board is selected to meet both safety standards and individual needs. The A2 product is called CORD, while the B1 variant is known as FOLT. This diversity enables overtec to offer tailor-made solutions that meet both the highest fire protection requirements and flexibility in use.
Overtec offers two different types of panels: the CORD and the FOLT panel. The CORD panel is available in the high-quality A2 quality, while the FOLT panel is sold in B1 quality. Depending on the product requirement, the panel thicknesses vary between 24mm and 40mm to meet the specific construction requirements. The CORD panel has a raw format of 335cm x 125cm, while the FOLT panel is offered in a raw format of 320cm x 125cm. This selection enables overtec to offer tailor-made solutions for different construction projects that meet both the highest safety and flexibility requirements.
The panels used by overtec are characterized by properties that comply with the requirements of EN13986. Our detailed product data sheets contain all relevant parameters that provide insight into the specific performance characteristics of the panels. In particular, they provide important information on fire protection, sound insulation and flexural strength, which are essential for different architectural requirements. This detailed information enables customers to ensure that the panels meet the required specifications for their building project and offer the highest safety and performance standards. The documents are available from our team on request.
The overtec panel can be easily processed directly on the construction site using a hand-held circular saw equipped with a hard metal saw blade or a diamond disk. However, it should be noted that processing becomes more difficult as the cement sets. It is therefore recommended that the overtec material be processed as soon as possible after delivery. The cut surfaces do not need to be specially treated, which significantly reduces the amount of work required. During the construction phase, a cover plate is attached to the top, which effectively protects the upper cut edge from water ingress and thus ensures the longevity of the construction.
The overtec panels are available in the raw formats 335cm x 125cm for the CORD variant and 320cm x 125cm for the FOLT variant. These generous dimensions enable flexible further processing and adaptation to the specific requirements of each construction project. The various products are worked out of the raw formats with millimeter precision to ensure an optimal fit and functionality in the application. This format selection ensures efficient use of the material and contributes to the realization of tailor-made construction projects. Please note that the thickness tolerances of each panel can vary by +-2mm.
The surface of the overtec panels can generally be plastered directly. However, the joints pose a challenge, as cracks are likely to form here due to different diffusion resistances and the expansion of the panels. To minimize this risk, the overtec panel is covered with a plaster carrier. This additional layer effectively eliminates the risk of plaster cracks and ensures a durable, aesthetically pleasing surface.
Overtec panels are versatile and approved for use classes 1, 2 and 3. Depending on the specific application, different static conditions are taken into account to ensure optimal stability and safety. Thanks to their robust nature, overtec panels can also be used in open weather conditions. This makes them ideal for applications such as plant pots or visible parapets, where they meet both functional and aesthetic requirements.
The overtec CORD panel achieves fire protection class A2, while the FOLT variant is classified as class B1. The fire resistance class of the 32mm CORD panel was rated EI60, whereas the 40mm CORD panel even achieves class EI90. On request, corresponding certificates from the Dresden Materials Testing Institute are available, which document these properties in detail and offer additional security for builders and planners.
Overtec systems are used in a wide range of applications, including parapets, parapets, shaft elements and plant pots. These systems are usually made up of three components: The panel material, which is standardized according to EN13986, does not require any special approval and thus ensures easy integration into construction projects. The metal components are manufactured in accordance with the applicable standards, such as EN1090, which ensures high quality and durability. In addition, the screw material meets the requirements of ETA 22/0221. This careful coordination of all components guarantees that the overall system complies with the necessary approvals and thus represents a reliable solution for a wide range of construction projects.
Overtec delivers as standard with semi-trailers that can be opened from the side and from above, allowing flexible unloading on site. On request, trucks with a lifting platform and unloading via a so-called ant can also be provided. Please note that special delivery requirements, such as delivery with a crane truck, may result in additional costs.
The thermal conductivity of the overtec CORD A2 board depends on the thickness of the board. For a thickness of 24 mm, the thermal conductivity (λ) is 0.251 W/mK and for a 40 mm thick board, 0.287 W/mK. These values
The thermal conductivity (λ) of the overtec FOLT B1 panel remains constant at 0.23 W/mK regardless of the panel thickness, which means that this panel conducts heat efficiently. The thermal resistance (R) varies depending on the thickness: at 24 mm it is 0.1 m²K/W, while at 40 mm it increases to 0.13 m²K/W. The U-value is 9.58 W/m²K (24 mm) or 7.67 W/m²K (40 mm) and shows the energetic behavior of the panel, which is taken into account in thermal engineering calculations.
The elastic modulus of the overtec CORD A2 plate, which describes the ability of the material to deform under load, is at least 4500 N/mm². This value, which is tested according to the EN310 standard, indicates the high strength and stability of the plate, which makes it particularly suitable for applications with mechanical stress.
The overtec FOLT B1 panel also has a modulus of elasticity of at least 4500 N/mm², measured according to the EN310 standard. This ensures high stability and resistance of the material and makes the panel versatile for construction applications that require robustness.
The bending tensile strength of the overtec CORD A2 board, which describes its resistance to bending under load, is at least 9 N/mm². On average, values
The bending tensile strength of the overtec FOLT B1 plate is also at least 9 N/mm², tested according to the EN310 standard. This strength makes the plate robust against mechanical stress and bending and is an important criterion for applications that require stability.
The weight of the overtec panels varies depending on the material density and is between 1,250 and 1,400 kg/m³. This means that a 40 mm thick panel weighs around 50 kg per square meter. This mass is an important factor in planning and installation, as it influences the load-bearing capacity of the supporting structures and makes the material particularly resistant.
The soundproofing properties of the overtec panel vary depending on the thickness. For a 24 mm thick CORD A2 panel, the sound insulation value is 33 dB, for 32 mm 34 dB and for a thickness of 40 mm 35 dB. These values
The screw pull-out of the overtec plate was determined through extensive tests at the Technical University (TU) Vienna and TU Graz as well as by the manufacturer of the screws. These empirical tests, which were carried out during the development of the overtec OneBit screw, guarantee reliable values, which are recorded in the European Technical Assessment (ETA 22/0221). This assessment ensures additional safety and standards in the application.
