The Lisrec Foundation was established to support and finance environmental projects, as well as to develop technologies and bring them into operation. Another key objective is to build a community of like-minded individuals who want to participate in positive changes...
Planting boxes are not limited to vegetables; they can also be used to grow herbs and various spices. The advantage is that, if necessary, the entire box can be removed and taken to the kitchen. After use, the box can be reinserted into its original place. This also allows plants to be protected from adverse weather conditions, such as frost, etc.
The entire construction system is a modular kit that allows for high creativity. Similarly, a small greenhouse can be created on the facade to accelerate seed germination and seedling planting. By utilizing the existing substrate box, combining aluminum tubes and food-grade plastic wrap, everything can be easily implemented at almost no cost, extending the growing season.
The material from which the construction elements are made is resistant to water, acids, and other mechanical influences. It is also resistant to plant growth. All construction elements are manufactured using calibrated molds under high pressure. This ensures maximum accuracy of the entire construction system. This allows for building with millimeter precision while maintaining all right angles and flat surfaces.
All construction elements are manufactured using calibrated molds under high pressure. This ensures maximum accuracy of the entire construction system. This allows for building with millimeter precision while maintaining all right angles and flat surfaces. Thanks to the unique and simple construction system that automatically ensures precision, even a moderately skilled builder can undertake construction using only the building plan.
A connecting pin is mainly used for simple walls and partitions with a thickness of 100 mm. It is also used for fencing. The pin also ties the structure horizontally and vertically between individual layers. This is a very strong connection that can be easily disassembled if needed. Due to the properties of these joints, the structure can be easily dismantled and reused to build a new one with a different shape and layout without losing functional properties.
Horizontal load-bearing structures for floors and ceilings are made of wooden KVH beams or planks, which are firmly mechanically attached to the load-bearing walls using steel beam brackets. The beam brackets are screwed into the body of the wall and secured from the other side. On the load-bearing wooden structures, a cover made from the same material as the construction system can be simply placed.
The shape of individual modules prevents splashing water from penetrating the structure and stops heat loss. The construction elements interlock and overlap. This shape allows the entire structure to be easily stacked together. When securing screws are used, they are concealed and protected under the protrusion of the second module.
A groove for pin insertion. Individual modules are interconnected using protrusions that precisely fit into the groove. These connections ensure high joint strength and maximum vertical and horizontal precision. The connection is achieved by simple insertion. The joints are extremely strong, tested in practice for hundreds of years, and can be easily disassembled if needed.
A structural spacer with openings for routing electrical distribution, data cables, water, and waste pipes. The spacer also connects the external and internal shells of perimeter and load-bearing walls. The openings are sized up to 110 mm for routing waste pipes with a standard diameter suited for residential houses and medium-sized operations. In cases of higher loads, the situation can be managed with parallel distributions connected outside the building or by utilizing the technical gap in the vertical direction up to a dimension of 250 mm.
Mounting facade elements can be easily removed, and the openings can be sealed with plugs. Everything is designed as a simple, mechanically strong system utilizing grooves and special pins. When planning a vertical garden or other elements on the facade, a special module designed for facade elements must be used during the construction of the building’s outer shell.
An exchangeable substrate box made of vermicompost for growing ornamental plants and food on the facade. It allows for the cultivation of various vegetables, including potatoes. When harvesting individual foods, the box can be easily replaced with a new one containing fresh seedlings, allowing continuous cultivation without affecting other crops. The boxes are made from the same material as the Lisrec construction system. They are resistant to water, acids, and other mechanical influences.
Interior surface treatment can be carried out using drywall boards without the need for steel profiles, which significantly reduces costs and shortens the installation time. The wall surfaces are perfectly even, and it is sufficient to simply screw on the boards and finish with gypsum putty. All fixtures such as sockets and switches are easily embedded into drilled openings, just as with drywall, and connected to already prepared electrical wiring.
Construction openings allow for separate vertical distribution of electricity and data cables without mutual interference. The cables are also protected. Cable routes in the structure are thus fixed, making it possible to calculate and prepare exact lengths of individual cables. This allows the builder to prepare most of the work themselves, leaving only the connection to be done by a specialist.
For horizontal routing of larger water, waste, and electrical distributions, the spacer has openings with diameters of up to 110 mm. Other technologies can also be routed through these openings. Everything is again filled with loose thermal insulation or another material.
In cases where horizontal distribution of water, waste, and electrical wiring is required, prepared openings are used, which are then filled with loose thermal insulation or another loose material. They can also remain empty for ventilation purposes.
The structural spacer connects external and internal construction elements. It is used for load-bearing and perimeter walls. It has openings for electrical distribution, data cables, water, and waste pipes. The openings filled with loose insulation also prevent thermal bridges between the external and internal wall shells. It is connected to other elements by simple mutual insertion.
The technical gap between the external and internal shells of the perimeter wall is filled with loose thermal insulation or another loose material according to the climate zone to increase thermal resistance. It can also remain empty for additional use in ventilating the building's structure.
The same modules as those used on other surfaces are used on the external side of the load-bearing perimeter wall. The openings in them can be filled with thermal insulation, thereby increasing the overall thermal resistance of the perimeter wall. If additional elements need to be attached to the building's facade, a special module must be used.
A short structural spacer is used for zig-zag vertical interconnection of additional spacers to ensure that individual horizontal layers are firmly connected. This prevents any risk of layers not being securely tied together. It is also used for finishing the height of the wall. It connects the external and internal shells of the building wall.
Openings in the structural modules allow for vertical distribution of water and waste even in a simple partition wall with a thickness of 100 mm. The gaps between the distributions and the walls are filled with loose thermal insulation or another material, depending on the climate zone. It is also possible to leave the gaps empty and use them for ventilation.
In case it is necessary to create a surface on the wall similar to traditional masonry, the wall is primed, and after drying, construction adhesive with reinforcing fabric is applied. The adhesive that penetrates the fabric is smoothed to an even level. Once the surface hardens, the final stucco plaster and paint can be applied.
