From his place of residence in a tourist city par excellence such as San Martín de los Andes, Mauro Querejeta, an expert who works in the housing construction sector, patented an invention that could revolutionize the industry..
It is the efficient brick Qbrick, (patented with the number AR096569B1), more specifically a three-layer masonry (brick) with which it is possible to build walls in a practical and simple way, with the addition of providing a high capacity for thermal and acoustic insulation that differentiates it from its similar bricks that currently exist (whether they are made of concrete, clay or those that are made through simple components, mainly sand, combined with cement, lime, and an expanding agent).
“This technology makes it possible to transform any known masonry into one with insulating capacities that even exceed international standards with unprecedented levels of energy efficiency. It is a three-layer brick made up of two external faces joined to an insulating core. Given the great possibility of combinations between bricks and insulators, the levels of k value (K value refers to the thermal conductivity of the elements, the lower the K value of an element, the greater its insulating property) reach extraordinary capacities. This results in a masonry with a real break in the thermal bridge, which, although a lot of technology is incorporated, does not change the treatment on site or the way of building traditional walls at all”, he told Infobae Querejeta.

Currently there are many construction systems focused mainly on energy efficiency, since currently, responsible energy consumption is not a marketing issue.
Bricks as a construction element have hundreds of years of existence in the evolution and construction of cities. They are embedded in the culture of humanity. Querejeta, expanded: “We all know that it is a brick, even in many cases it is used as an investment refuge and many allocate their dollars in the segment so that the currency is not devalued or it appreciates more strongly.”.
According to the inventor of the brick that was patented before the National Institute of Industrial Property (INPI), he said the following: “I came up with the idea of creating it, I thought of that acquired right and instead of trying to radically change the way of building (such as current building systems), I tried to incorporate technology into one of the oldest and most used elements by man (currently they are produced and consumed more than 100 million bricks per month in Argentina)”.
Today, to use any industrialized or modular construction system, highly qualified labor is necessary, this makes the progress of dry building very slow, argue from the brick sector.
Querejeta, maintained that his intention is “that the sector can put a brick like this in the hands of its clients, and in this way it would be working on a hinge point for the future of sustainable construction. If we could imagine that such a high percentage of traditional buildings were made with a super efficient brick, we could even think about changing the energy matrix of a country. Energy savings could exceed by more than 50% compared to what we know”.
There are two ways to manufacture these efficient bricks, one by polyurethane injection and the other by adhering to the core of the Expanded Polystyrene (EPS) pieces.
“During these years we have contacted one of the world’s leading automation companies, based in Germany, with whom we developed a fully automated production line for polyurethane injection capable of producing more than 12 million units per year. They are compact productions designed to be installed at the end of the brick manufacturing lines”, said Querejeta.
Another advantage is that a brick can be achieved at a very low cost in the work. Obviously, when large-scale production is achieved, the values will be competitive. “Today we find ourselves in different negotiations with very important companies, including some that do not belong directly to the brick sector, but with a very strong presence in the construction market that look very carefully at the volume that is handled in the industry, both they Like us, we see a great opportunity in this market, which is so big,” said Querejeta.
According to data published by the different brick factories, a volume of at least 80 million bricks per month is estimated, which gives approximately 5.5 million square meters of walls per month.
Fraud 48 yearsMauro Querejeta has always been linked to invention, innovation and the world of construction (sale of materials).
“My family has had a company linked to the industry for more than 40 years. My profile is that of an entrepreneur, from a very young age I was very curious about everything related to the new and different. I define myself as a pure entrepreneur. I always wanted to travel my own path, this is how among many things, one of the most transcendental that I did was the creation and incorporation, more than 15 years ago, of the SIP construction system (paneling) in Argentina, currently one of the most consolidated industrialized systems in the country, as you will see, not for this reason have I stopped thinking that there is always something more”, he concluded.
