Undoubtedly. The unique composition of the polystyrene ensures exceptional water resistance, maintaining its key properties even with long-term exposure to moisture. Additionally, foam polystyrene excels at resisting microbial growth – it does not decay, mold, or undergo natural degradation. These characteristics make the ForSimplex system an ideal choice for construction in high-risk areas with a heightened flood danger.
Practical experience confirms that the ForSimplex system reliably lasts for at least 70 years. Laboratory tests simulating long-term use even suggest that the material remains unchanged after 150 years. Expanded polystyrene (EPS), which forms the basis of the system, has been used in the industry since 1951.
This versatile material is particularly known for its durability due to its unique structure – 98% of its volume consists of air. This ensures that EPS maintains its original properties throughout its lifespan.
EPS is non-toxic, resistant to moisture, and does not rot. Studies have shown that it does not undergo the typical aging process. With proper application and protection from UV radiation and organic solvents, EPS can theoretically last indefinitely. These characteristics make the ForSimplex system an exceptionally durable and long-term reliable solution.

The ForSimplex construction system offers customers a range of advantages over conventional building methods. Thanks to the unique polystyrene blocks with an integrated locking system, it is possible to create energy-efficient housing with minimal heating costs, quickly, efficiently, and economically. This innovative system is characterized by exceptional versatility. It is the ideal choice for construction in demanding conditions, whether it’s flood-prone areas, locations with problematic soil, or hard-to-reach plots of land.
The simplicity of assembly makes ForSimplex attractive for self-builders. After a short training session, even construction novices can work with this system, significantly reducing overall project costs.
In addition to excellent technical parameters, ForSimplex also offers health benefits. It creates an environment with an optimal microclimate, which is especially appreciated by people suffering from allergies or asthma. This makes the ForSimplex system a response to the growing demand for healthy and comfortable living in modern society.
The ForSimplex system is essentially a construction kit for adults, with concrete as its structural element. With the help of formwork, it becomes a homogeneous thermal polystyrene block. Thanks to the perfect lock between individual blocks, a flawless formwork is created, and after pouring concrete, insulation is provided. The concrete fill has a thickness of 150 mm, and depending on the concrete class used, it is stable enough to meet the requirements of a load-bearing wall up to several stories high. The rigidity of the structure at greater heights is ensured by the inserted steel reinforcement.
Expanded polystyrene saves energy. Polystyrene insulation has been used for almost 50 years and serves as an insulating barrier against cold, heat, and noise in millions of apartments and houses worldwide. Polystyrene offers significant energy savings and environmental protection. Every thermal insulation used in a building reduces harmful emissions from chimneys and conserves valuable raw materials. It is a fully recyclable material that is easy to process.
No, EPS (expanded polystyrene) is a completely safe material. Due to its inert nature, it poses no health risks. Its versatility and non-toxicity allow for wide usage, including direct contact with food. EPS does not alter the taste or aroma of food and meets strict hygiene and safety standards of developed countries.
This material is used in many areas where the protection and safety of people are paramount – from bicycle helmets and life-saving floatation devices to special packaging for medicines and transport boxes for human organs.
EPS can be handled without special protective equipment like gloves, goggles, or respirators, confirming its safety for both workers and end users. Thanks to these properties, EPS is considered a health-safe and environmentally acceptable material with a wide range of uses.
Expanded polystyrene is used in a surprisingly wide range of industries due to its health safety. For half a century, it has been used to make flowerpots, with its flaked granules serving as effective drainage in ceramic containers. This property supports healthy plant growth and rapid development.
In horticulture and agriculture, polystyrene plays a key role, especially in the implementation of green flat roofs. Its safety for human health is further confirmed by the fact that it is commonly used as packaging material for food – from cheeses and meats to fruits and vegetables. This versatile material proves its value not only in construction but also in everyday life, where it comes into direct contact with food and plants.
Expanded polystyrene excels in its recyclability and minimal environmental impact. When disposed of in landfills, it does not release harmful substances into groundwater, making it a safe material even after its lifespan. Its use in agronomy is also interesting, where granulated polystyrene waste serves as a soil conditioner, improving the structure of heavy soils. This application demonstrates its potential beyond construction.
In industry, EPS production waste is effectively reintegrated into the production cycle or used as an additive in concrete and thermal insulation plasters. These aspects confirm that expanded polystyrene is a material with a high degree of sustainability and versatile use even after its primary phase of use.
The ForSimplex construction system uses an advanced self-extinguishing material with an integrated flame retardant. This innovative solution significantly increases fire resistance and slows down the spread of any potential fire. Thanks to these properties, the EPS used in our system is not only safer but also a more reliable choice for modern construction. ForSimplex thus offers an optimal combination of thermal insulation and fire protection.
The myth of “toxic fumes” from burning polystyrene is greatly exaggerated. Foam polystyrene does not release significantly more harmful substances during combustion than other common building materials of organic origin. It is widely known that burning any materials, whether natural or synthetic, leads to the release of potentially dangerous compounds.
However, experimental studies have shown that polystyrene does not deviate in this regard. When burned, it primarily produces carbon monoxide, and in such low concentrations that laboratory rats exposed to these fumes survived, unlike in experiments with burning wood. Interestingly, alternative insulation materials like cork or wood fibers produce even higher concentrations of CO when burned than polystyrene.
This is also true for most household items – furniture, curtains, or carpets. The fire risk of polystyrene insulation is further reduced by the fact that only self-extinguishing versions of this material are supplied for construction in the Czech Republic. These findings dispel the widespread concerns about the supposed extraordinary danger of polystyrene in fires.
It is common to hear that thermal insulation must “breathe.” Let’s take a closer look at this issue. Only about 4% of air exchange and humidity pass through the walls. The main moisture removal is provided by windows, chimneys, or range hoods. Reducing this value by half does not have a significant impact on the house’s climate. This is proven by millions of timber buildings with vapor barriers in the walls.
For ventilated structures, a lower diffusion resistance factor (fL) of insulation is more advantageous. On the other hand, for non-ventilated structures, such as single-ply roofs or external thermal insulation systems (ETICS), higher vapor permeability is less desirable. This is because the material above the insulation typically has a higher diffusion resistance, which can cause condensation.
For single-ply roofs, the ideal insulation material is one with the most closed structure possible. Highly diffusive materials require high-quality vapor barriers in this case. EPS with medium permeability (fL = 20-50) is often used in non-ventilated structures.
Concerns about internal moisture and mold have not been confirmed after 70 years of usage. Thanks to the water resistance of EPS, moisture can only appear under extreme conditions and is easily visible. In traditional materials, moisture penetrates into the structure, reducing their thermal insulation and making ventilation more difficult. In contrast, EPS retains its thermal insulating properties.
In the past, when heating with wood or coal, the thermal mass in load-bearing walls played a key role. The uncontrolled increase in heat was stored in the masonry and gradually released into the interior. However, today’s reality is different. Gas and electric heating systems now dominate, offering more precise regulation.
The current generation faces a higher incidence of allergies and asthma, which emphasizes the importance of indoor air quality and efficient ventilation. Our system meets these requirements. Modern heating systems, which respond to temperature fluctuations as small as 0.5°C, make the massive thermal mass in load-bearing walls unnecessary. The primary focus is on heating the interior space, not the structure.
With the use of heat recovery ventilation, airtight insulation is crucial, which our ForSimplex system ensures with minor adjustments. To balance the temperature within the building, the thermal mass of interior walls, ceilings, plaster, and furnishings is sufficient. The thermal mass function of the external load-bearing walls is no longer essential.
Living in a house built with the ForSimplex construction system offers exceptional comfort thanks to several key factors. To create a pleasant and healthy environment, the difference between air temperature and the surface temperature of the walls is crucial. Typically, if a wall is more than 3°C cooler than the air, it creates an unpleasant “drafting” effect, which can lead to health complications, including rheumatic issues and increased dust circulation.
However, ForSimplex walls, due to the integrated thermal insulation layer, maintain the surface temperature close to the air temperature, even under extreme outdoor conditions. The difference does not exceed 1°C, which ensures optimal thermal comfort and creates ideal conditions for comfortable living without negative health effects.
Attaching objects in the ForSimplex system is surprisingly easy and effective. For lightweight items up to 5 kg, a standard screw is sufficient. It passes through the plaster and anchors in the polystyrene. Heavier objects, up to 80 kg, require a wall plug that goes through the polystyrene and anchors directly in the concrete.
In cases where increased load is expected (e.g., for toilets, handrails, or kitchen units), it is advisable to use a wooden batten or to encase the space around the wall plug in the polystyrene with concrete. This prevents the potential for breaking out.
When working with a connecting partition, it is necessary to first fill the hole with concrete and then drill again. An interesting fact is that by using a longer wall plug that reaches into the concrete core, maximum stability is achieved.
In general, it can be said that installation into the ForSimplex system is no more difficult than with other building materials. For optimal results, we always recommend following the assembly instructions of the specific manufacturer.
Surface finishing of the building structures offers a wide range of options. Thanks to the precisely flat walls of the ForSimplex system, thinner layers of plaster can be applied, saving both time and material. The exterior is already prepared for the installation of an insulation system, which typically includes adhesive, reinforcing fabric, primer, and final plaster.
A modern trend also includes decorative strips or facing bricks, which give the facade a unique character. Inside, you can choose between directly gluing drywall boards to the prepared walls or applying traditional thin-layer plaster. A significant advantage of the ForSimplex system is the absence of any restrictions regarding surface finishes, providing maximum flexibility when choosing the final appearance of the building.
Carrying out electrical and plumbing installations in the ForSimplex system is very straightforward. Using a resistance wire or a similar tool, a precise groove is created for laying pipes or cables. This innovative method eliminates dust and the creation of heavy debris, which are typical of traditional methods. After the installations are laid, the groove is filled with PUR foam and then covered with plaster.
The entire process is clean and quick – polystyrene offcuts can easily be cleaned up and disposed of in a regular plastic bag. This method significantly simplifies and speeds up both electrical and plumbing installations, which is appreciated by both professionals and DIY enthusiasts.
The installation of window and door elements follows the specific guidelines of each manufacturer. The frames are fixed either with wall plugs or special anchors, which are secured directly into the load-bearing concrete core. This method ensures maximum resistance against forced entry. Additionally, the frame is protected on the outside by a system solution that includes precisely executed reveals and lintels, which enhances the overall tightness and insulation properties of the installation.

Definitely yes. We have direct experience with the destructive tornado in South Moravia. In the village of Hrušky, we built two structures that underwent this fiery test. After the tornado passed, the load-bearing structures remained completely intact, and only the external insulation suffered local surface damage. Thanks to the robust concrete core and strategically placed reinforcement, our buildings are capable of withstanding even such extreme natural events. This real-life experience confirms the extraordinary durability of our construction system.
Concrete is not only biologically safe but also a versatile building material. Its safety for living organisms is demonstrated by its use in arboriculture, where it is used to treat tree injuries. In modern construction, it has become an indispensable part of many structures. From prefabricated blocks and reinforced concrete ceilings to beams and other building components, concrete is a key material without which today’s architecture and engineering would be unimaginable.
The answer is simple: the future belongs to energy-efficient and ecological solutions. The ForSimplex system clearly surpasses conventional methods in this regard. It offers thinner walls with a precisely defined insulation layer, leading to optimization of space and thermal efficiency. Additionally, it minimizes wet processes, which accelerates the completion of construction. Easier transport of materials and almost zero waste save time, money, and the environment.
