Are you looking for a simple and lightweight balcony railing?
These 3 advantages are obvious with overtec:
More work steps cannot be combined into one product. A brief description of the invention:
The overtec parapet consists of a wood cement panel (3a), which has one or more prefabricated millings. The material thickness is 40mm (t), with a standardized element length of 1.25m. The parapet height is individually adjusted to the required size. A metal post (2) rests in this plate milling. Overtec screws (7-2b’), which are approved according to ETA 22/0221, are used for the connection between the wood cement board and the metal stud. The parapet is usually erected vertically, in an extension of the outer edge of the wall. The parapet can either be designed as ceiling edge formwork (Figure 7) or screwed onto the solid ceiling (Figures 1 and 3). With the screwed-on variant, it is also possible to move the parapet outwards up to 15cm above the edge of the concrete ceiling, into the insulation level. This creates usable balcony space. A facade structure is installed on the outside of the parapet (2ba). The sealing and a plaster base are on the inside (2bc). A cover plate is attached to the top, analogous to the overtec attic.

Not just object-related, but tailored to the individual installation situation.
The interaction between plate, angle and screw is what matters. Together with the best structural engineers in Austria and Germany, we have programmed a calculation algorithm that delivers precise results for the object and product. A variety of individual influences are important in order to be able to check which product can be used. These are, for example: The sea level, the base wind speed pressure, the terrain category, the installation height in the building, the roof structure and thus the wind attack area on the overtec, the facade structure, the payloads of the terrace, the usage class, the molding value, the concrete quality and so on. Under certain circumstances, there may even be substantially different load zones and product utilization within one property.

A parapet or balcony parapet is a structural barrier that runs along the edge of a balcony or terrace to prevent falls. It can be made of different materials, such as wood, wood cement, steel, aluminum or glass, and can have different designs and patterns to fit into the overall aesthetic look of the building. A parapet can also significantly shape the facade of a building and set visual accents. It is important to note the safety requirements for balustrades and railings to ensure they comply with local regulations.
The overtec parapet is characterized by the fact that it is made from a single-shell, solid, 40mm thick wood cement board in accordance with EN13986:2004+A1:2015. The overtec parapet is attached vertically to the building using a metal stand in the foot area. This can be done via a concrete-encased or screwed-on connection. All metal parts are galvanized. The wood cement board is approved for use classes 1, 2 and 3 and can therefore remain open not only during the construction phase, but also permanently. The slim overtec parapet can save up to 63% in emissions. Other components that can also be reduced through weight reduction are not yet taken into account.
Anyone planning a parapet or a parapet construction should be aware that it is safety-relevant and that the standards must therefore be strictly adhered to. Minimum fall heights and minimum impact loads must be observed. Depending on the application, the parapet height should be at least 1 meter and can be even higher depending on the installation height in the building. In addition, minimum impact loads of 0.5kN in private balcony areas and 1.0kN in public balcony areas must be accommodated. The use of the area plays an important role in the requirements for the parapet construction. For example, there may be additional requirements regarding impact loads or fire protection if it is an arcade, an escape route, or the like.
A parapet can be used both indoors and outdoors and often serves as a balcony or stair railing. When dimensioning the parapet, the position and intended use in the building are particularly important. An important question is whether there can be large gatherings of people near the balcony railing. Depending on the area of application, a distinction is made between arcades, staggered floors, escape routes, stair railings, private balconies and public balconies. It is essential to take both the static and the building physics aspects into account when planning parapets. This ensures that the parapet meets the requirements and ensures safe use.
In addition to static and building physics aspects, the parapet also plays a crucial role in the feeling of living and space. In a heavily populated area, an open parapet can lead to residents attaching an opaque tarpaulin to it, which affects the overall appearance and the architect’s planning idea. To avoid this, an optimal parapet construction is essential. It allows an unrestricted view in both standing and sitting positions while also providing privacy to protect residents’ privacy. A well-thought-out parapet can therefore make a significant contribution to ensuring that a living space is perceived positively.
With fire behavior of A2 or B1, we deliver the parapet according to your requirements. Depending on the version, it can achieve a fire resistance of EI90. The panel tests at MPA Dresden prove that the material has a fire resistance of EI60 in the form of a 32mm panel and EI90 in the form of a 40mm panel. Overall, the overtec parapet is ideal for objects where special fire protection requirements must be met, especially in the area of arcades and staggered floors.
The overtec plate proves to be extremely durable and robust. It offers the best conditions, especially in terms of weather resistance and frost resistance. The material can not only remain freely weathered during the construction phase, but can even remain as a visible product in a freely weathered and uncoated form for decades.
Yes. However, the choice of the suitable overtec variant depends on the scope of the structural measures. If you want to keep your concrete ceiling intact, a screwed-on parapet is best. However, if a new ceiling is to be poured, you can also consider a parapet embedded in concrete. No matter which option you choose, overtec offers a variety of balcony railings that can help you renovate your balcony.
Example Mannheim: The overtec balcony parapet is a special example from Baden-Würtemberg. The video shows how the parapet can create up to 35cm of space in the staggered floor thanks to the shifting of the elements outwards into the insulation level. The result is a larger balcony area for the lifelong resident. This innovative solution will certainly cause enthusiasm not only in Mannheim, but also among planners, architects and builders in other regions of Germany. Watch this video and see the benefits for your building project.
Example: St. Mary's: An arcade places special demands on the parapet, as gatherings of people can occur in these areas. It is therefore important to ensure a high impact load of 1.0kN per linear meter. This requires particularly massive construction, as an example from Sankt Marien in Upper Austria shows. Especially in arcades that are also used as escape routes, increased fire protection requirements often have to be taken into account. If you are planning a project with an arcade, we are happy to work out the details with you.
In this video you can follow the step-by-step construction of the overtec parapet. By finishing the elements on disposable pallets with a small cubage, more linear meters of parapet can be transported on a truck. A crane is not necessary for low elements, but it is necessary for higher ones. Elements can be cut to fit exactly where necessary. After concreting, the elements are sealed, the insulation and the wall covering are attached. If you plan for it, you can attach a stainless steel railing, a glass railing or a simple handrail to create more patio space.
Our library of planning details offers a wide range of applications for the overtec parapet. You can click through and discover the perfect use case for your project. Our experts will be happy to provide you with the appropriate detail in various formats such as DWG or as a 3D element in IFC or STEP. With this practical information you can adapt a stainless steel railing, a glass railing or a handrail to your needs and ensure your fall protection. In addition, the closed part of the parapet can also serve as a privacy screen on the balcony. If you have any questions about planning details for your project, please do not hesitate to contact our team.
overtec increases the balcony area by up to 35cm per linear meter. In this way, we create more usable space and get even more terrace space out of your property. Ideal for the project developer and also for the resident.
overtec counteracts the shortage of skilled workers by increasing the level of prefabrication. When setting it up, we analyzed every move and reduced it to a minimum. All steps are presented in languageless installation instructions and videos to ensure error-free installation.
overtec uses up to 63% less emissions compared to conventional designs. And that's not all. By saving weight, other elements such as reinforcement, concrete thickness, ISO baskets and sheet metal thickness can also be saved.

An overtec parapet is manufactured according to the construction drawings and requirements of the building project and can be made in different heights. The minimum height is usually 30 cm, while the maximum height is limited to 180 to 200 cm. For parapets that do not fully reach the prescribed fall height of 1 m or 1.10 m, an additional handrail or railing is required to ensure fall protection.
The overtec parapet is designed to be able to withstand all regional loads. The load parameters are calculated based on the postcode of the construction project and take wind, snow and earthquake loads into account. In addition, the parapet can withstand person loads between 0.5 and 1.2 kN. This stability ensures the safety and longevity of the construction.
Parapets are subject to different standards in the DACH countries, as each country has specific requirements for construction products. Although there are European standards that apply across the board, DIN must be taken into account in Germany, ÖNORM in Austria and SIA in Switzerland. These standards contain additional national adjustments and parameters that are adapted to regional requirements and thus ensure the safety and functionality of the parapet.
An overtec parapet has a thickness of 40 mm as standard, which offers high stability and excellent load-bearing capacity. The cover plate is usually 24 mm thick, but can be made 30 or 32 mm thick if required to meet regional requirements. This thickness offers an optimal balance between robustness and aesthetic appearance.
The parapet is made of a 40 mm thick overtec panel, which ensures high stability and load-bearing capacity. Depending on the specific quality requirements of the project, either CORD A2 or FOLT B1 quality is used, both of which represent a robust and durable solution for the construction.
The surface of the overtec parapet can be left untreated, painted or provided with a curtain wall. Other surface finishes include plastered facades, clinker brick facades or clinker brick slips. When choosing the facade, the specific instructions and installation regulations of the facade manufacturer must be observed in order to ensure a permanently stable connection.
Planning documents for overtec parapets can be downloaded from the website overtec.com or from the platform Ausschreiben.de. These are usually available as PDFs and contain detailed information that facilitates the planning process. File formats such as DWG and PLN, which are specifically designed for digital planning, are also available on request.
The standard planning documents are provided as PDFs, which is the common solution for uncomplicated handling. For detailed planning in CAD software, the files can also be provided in DWG or PLN format on request to enable direct integration into the planning software.
Yes, a railing can be attached to an overtec parapet. In such a case, however, it is necessary to take this into account at the planning stage to ensure that the parapet can safely support the railing's beam loads and that the connection to the building is optimally designed. Overtec offers advice to ensure a stable and safe installation of the railing on the parapet.
There are three main types of parapets, depending on the height and railing connection:
Type 1: Here the railing is mounted directly on a small post of the parapet. This type is usually used for parapets that only protrude slightly from the floor structure.
Type 2: The overtec plate is higher, but does not reach the full fall protection height. Here an additional handrail or a low railing is attached directly to the parapet.
Type 3: The overtec plate reaches the full fall protection height, so no additional railing is required. This type ensures maximum safety and stability.
The cover plate on the overtec parapet is pre-milled at the factory to ensure a slight slope for drainage. In addition, pre-drilled holes for the screws are already present so that the plate can be installed easily and precisely. This factory processing ensures that the cover plate fits exactly and that no alignment errors occur on site.
In principle, internal insulation for thermal insulation is not absolutely necessary. However, a plasterboard on the inside is advisable if a plastered surface is desired. This plasterboard covers the joints of the parapet and ensures a clean and even plastering, which increases both the aesthetics and the functionality of the parapet.
The plaster base on the inside of the parapet is used to create a flat surface that can be plastered. A ETICS material (external thermal insulation composite system) such as EPS or XPS is often used, which has a thickness of 3-4 cm. The plaster base ensures that the joints of the overtec panel are covered and that the plaster forms a uniform surface that can withstand mechanical stress.
Yes, direct plastering of the overtec parapet is generally possible. However, the vertical joints must not be plastered, as material expansion and different diffusion resistances can cause tensions that lead to visible cracks. In most cases, it is therefore advisable to use a plaster base board that covers the joints and ensures a long-lasting, uniform plaster surface.
Whether internal insulation is necessary depends on the specific application. In terms of thermal bridges, internal insulation can often be omitted if the parapet is dimensioned accordingly. However, for a uniform and aesthetic plastering, it is recommended to use internal insulation that conceals the joints of the panel and creates a clean surface.
Yes, the overtec parapet has been tested in practical pendulum impact tests to check its stability and safety. Various parapet types, heights and railing connections were tested under load with a standard glass ball bag. These tests ensured that the structures meet the necessary safety requirements and offer a high degree of reliability and stability.
An overtec panel weighs an average of 50 kg per square meter. The additional metal components of the parapet vary in weight and can be between 5 and 15 kg. A complete parapet with a height of 150 cm and a length of 125 cm therefore has a total weight of around 120 kg. For safety reasons, mechanical lifting is recommended for heavy parapets weighing around 50-75 kg or more.
Yes, parapets less than 1 m high and weighing less than 50 kg can be moved by hand. However, for higher and heavier parapets, crane support is recommended. In such cases, a lifting loop hole is provided as standard in the panel to facilitate lifting and moving with a crane.
From a height of 100 cm, a lifting loop hole is installed as standard, which allows the parapet to be lifted with a crane. A lifting loop hole can also be integrated for smaller parapets on request. This makes it easier to lift and precisely position the parapet on the construction site, which ensures quick and safe assembly.
A pallet typically contains around 10 parapet panels, with each panel weighing up to 1,500 kg. The number of panels per pallet can be adjusted to suit specific weight restrictions on site. Please note that this may result in a greater number of loading metres required in transport.
Simple and readily available tools are required to erect an overtec parapet. These include a spirit level, rubber mallet, cordless screwdriver and chalk line for alignment. If necessary, a crane should be used for support, especially for heavy parapet elements. A hand-held circular saw with a carbide or diamond blade is required to adjust the elements on site if necessary.
As standard, no installation or assembly plan is created, as the elements are designed to be sold by the meter and do not usually require specific planning. However, if the floor plan has more complex requirements, such as immovable emergency drainage or railing connections, an installation plan can be created for an additional charge. This helps to optimize the construction process and ensure the precise positioning of the elements.
The delivery time for an overtec parapet is usually between 2 and 8 weeks, depending on the time of year and the current order situation. As soon as all technical details have been approved, the production and preparation time begins. For items not in stock, a lead time of 6 to 8 weeks is recommended. It is also possible to reserve a later delivery date if planning adjustments are still required.
Yes, the overtec parapet is suitable for outdoor weathering. The overtec CORD panel is approved according to service class 3 and can therefore withstand even the harshest weather conditions, both during the construction phase and in its intended condition. However, a reduction factor is taken into account to ensure the service life of the material in the event of prolonged weathering.
The overtec parapet has been tested as a substrate for adhesive systems by various facade manufacturers, such as Capatect, Sto, Baumit and Alsecco. These tests have shown that the board has excellent adhesion strength for full thermal systems, provided the manufacturer's instructions are followed. This makes the overtec parapet ideal as a support for external thermal insulation composite systems.
Standard substrates for the exposed parapet are cast-in-place concrete ceiling formwork, as they offer a high level of precision and stability. Ceilings that have already been concreted are considered special substrates, as their structure requires more complex and precise assembly. The exposed parapet is therefore particularly suitable for cantilevered, thermally separated balcony components where a stable and precise structure is required.
