Like Toy Blocks: The Innovative Modular Construction Invention That Doesn't Use Cement

In recent times, new technologies have enabled the creation of systems capable of building houses in a more economical and environmentally friendly way. Among the most interesting alternatives is an invention that aims to reduce construction times and simplify a significant part of the building process.

The proposal originated in Europe and replaces traditional materials with a system of prefabricated pieces that fit together seamlessly. The result allows for faster execution, reduces construction waste, and provides a higher level of thermal insulation and fire protection.

What This New Architectural Method of Blocks Is About

The European company SYSTEM 3E developed a modular building system based on blocks made from expanded perlite, a volcanic material that changes its properties when exposed to very high temperatures. This process multiplies its volume and creates a structure filled with small air chambers.

Thanks to this composition, the blocks offer thermal insulation, low weight, and high fire resistance without the need to incorporate additional materials, such as cement, mortar, or adhesives to join the pieces. Each block features a high-precision interlocking design that allows them to be connected like a puzzle.

If the foundations are already completed, the main structure of a house can be finished in just one day. Moreover, since wet processes are eliminated, the construction generates less waste, and building tasks can continue even when weather conditions are unfavorable, as the installation of the blocks does not depend on the drying of mixtures.

Perlite was already known for its insulating capacity in various construction products, but in this case, the novelty of SYSTEM 3E lies in turning this material into a structural component capable of bearing loads and forming part of the main structure of the dwelling.

Key Details of This Invention

The manufacturer offers various prefabricated kits to meet different needs; for example, the available models range from 24.88 square meters for offices or auxiliary spaces to 152.41 square meters designed for family homes.

It also sells a compact version of 9.91 square meters, with a starting price of around 5,777 euros, excluding taxes. On the other hand, the largest model is 123.92 square meters, priced at 41,960 euros without taxes. Each kit includes structural blocks, doors, windows, and the basic roof structure. The buyer must separately ensure the construction of the foundations, electrical installations, plumbing, interior finishes, transportation, and the necessary permits.

One of the best features of this system is its fire resistance. Walls built with these blocks achieve a classification of REI 240+M, a level that allows for maintaining load-bearing capacity, structural integrity, and thermal insulation for 240 minutes in the event of a fire.

Additionally, regarding energy efficiency, the structure reduces temperature losses both in winter and summer, helping to decrease heating and cooling consumption. The low weight of the blocks facilitates transportation to the site and simplifies assembly. Due to its characteristics, the system can be applied in family homes, country houses, independent studios, private offices, and tourist accommodations.
