Cortizo develops new minimalist aesthetic solutions in its systems

CORTIZO bets on enclosure systems that combine high thermal and acoustic performance with state-of-the-art designs, factors that star in the demands of the market and its innovation strategy. For this reason, the R&D&I department of the Galician multinational continues to develop new accessories for the most demanded series with the aim of improving its manufacturing, installation and handling, but without altering the aesthetic harmony of the whole.

The Galician multinational expands its range of accessories with a closure integrated in the central knot for the COR VISION PLUS slide and with the hidden drainage system for the COR 70 Industrial series, COR 70 Hidden Sheet and COR 70 Hidden Blade C16 ST

Following this line, the padd aftermarket has just launched a hidden handle for the manual opening of the COR Vision Plus system. The new solution integrates the closure into the central knot, making it imperceptible in the front view and allowing to completely hide the lateral encounter of the inner sheet, as in the motorized version. It is a hidden closure that can be lacquered in any color, thus giving greater uniformity to the whole. With this solution, the minimalist line of this premium slide is reinforced, which also incorporated in the last year the option to fully fill the lower profile and integrate it with the finish of the floor (pavement, floor, ceramic…), thus achieving a transition without any obstacle between the interior and exterior of the house.

On the other hand, CORTIZO has also expanded the range of accessories for its hinged windows, developing a new hidden drainage system for the COR 70 Industrial, COR 70 Hidden Blade and COR 70 Hidden Blade C16 ST series. This solution is based on the incorporation of a new gasket at the bottom of the frame to evacuate the water, replacing the usual drainage caps placed on the front. This results in a totally clean exterior aesthetic, without any complement in the frame, at the same time that the installation of the window is facilitated, allowing to place the base of the frame on the work itself. These hinged systems also feature hardware and accessory options that minimize the visual impact on the inner side of the window. Among them, highlights the new hidden hinges of 180o, which allow the total opening of the leaves, or the new handles: Arch Invisible, imperceptible in the front view and designed for the COR 70 Hidden Sheet of European channel, and Minimalist, valid for all series hinged and based on a careful design in which the shield is dispensed to enhance the avant-garde aesthetics of these carpentry.

Aluminium, materials in which the coronavirus remains for the less time

Several provinces and municipalities have progressed in the de-escalaada process, moving to phase 1. One aspect in which, throughout the health crisis, the focus has been on the shortening of the cycle of virus contagion, has been at the time of its survival on different surfaces. Something we will have to continue to pay attention to in the successive phases of de-escalation to avoid possible upturns and aggravation of the improvement situation that we are gradually achieving.

To this end, the Ministry of Health presented through a scientific-technical report the survivability that the Covid-19 has in different materials, something to which factors such as humidity, temperature and, of course, the material itself will affect. Based on his own research on the persistence of other coronaviruses on inanimate surfaces outside an organism, from The Journal Of Hospital Infection estimates that the Covid-19 would survive 2 to 8 hours on aluminum, compared to the 2 days it would on steel, the 4 days it would do in wood and glass, or 5 days in metal and ceramics. Finally, plastic would be the surface between those analyzed (all of them daily surfaces and present in our environment) where the longest would survive: more than 5 days.

Outside of a human organism, it is estimated that the Covid-19 would survive between 2 and 8 hours on aluminum, compared to the several days it would on other materials such as plastic.

With this data in hand, from the AEA – the Spanish Aluminum Association, which represents more than 600 companies in the sector – we want to claim the importance of aluminum as a material in areas such as sanitary, where measures for the containment of the virus must be as demanding and effective as possible.



Centers that have been decisive during the current pandemic situation, such as the three field hospitals set up in Valencia (next to La Fe de Valencia and the two Generals of Alicante and Castellón), had aluminum as a fundamental structural material. A decision that was not at all casual; if these field hospitals were to receive hundreds of infected patients, it was necessary that the predominant and present materials were those in which the virus had a shorter survival period.

The Ministry of Health, Ana Barceló, speaking of the safety of these three enclosures, pointed out precisely that they had been mounted with materials such as aluminum – instead of steel or iron – because the coronavirus would not survive more than two hours on these surfaces.

And not only that; In addition, they needed to be built quickly, while it was necessary to ensure the stability of the structure. Under all these premises, aluminum was shown to be the ideal material for these purposes. Jon de Olabarria, Secretary-General of the AEA says “One of the sectors in which aluminum stands out is undoubtedly that of temporary structures. All this thanks to its ease of assembly and its lightness for transport and placement. Despite its low weight, it is a solid, hard and resistant material, which gives stability and safety to the structures. If we add to this that this is one of the surfaces on which the Covid-19 least resists, we are faced with a material that must prevail in areas such as sanitary.”

The Spanish Aluminum Association claims aluminium as one of the preferred materials for sectors such as health while the pandemic situation lasts.

In short, says Jon of Olabarria, “Among the materials that are most present in our daily lives and in the objects that surround us and that pass constantly through our hands, aluminum has been shown to be one of the least favors the permanence of the virus in it, which should place it as a prevalent material in the future or, at least, until a vaccine against Covid-19 is found. It is clear that we must maintain a strictness and consistency in the work of cleaning and disinfection more intense than ever. But on top of that, it will always help that those elements around us are surfaces or objects that we know safe after a couple of hours.”

On top of that, the AEA emphasizes that aluminum is a total and infinitely recyclable material without its qualities being diminished in successive recycling processes. Also, for the recycling process it requires only 5 of the energy that was needed to produce primary aluminium. However, any element that is created and used in the context of this pandemic and then discarded can be recycled and have successive and infinite lives.

New range 4900 Cortizo

Cortizo launches the new 4900 Corredera system, a standard sliding window with excellent thermal and acoustic features, characterized by a straight and avant-garde aesthetic with a reduced central knot of only 35 mm that allows to maximize the glazed surface of the window, thus favoring the entrance of light inside the rooms.

The 4900 Sliding system allows combinations of up to 6 sheets, with maximum dimensions each of 2200 mm wide and 2600 mm high, and weights of 240 kg.

The new Cortizo slider was born as an evolution of the 4200, one of the most demanded by its customers in recent years, and stands out for its great thermal insulation (Uw from 1.2 W / m²K) and acoustic (Rw up to 40 dB ), characteristics that come favored by its great capacity of glazing of up to 36 mm, which allows the installation of triple glasses, as well as by the break of thermal bridge with polyamide rods of 34 mm.

Detail of the new Cortizo 4900 series.
All these characteristics are reinforced by the great results obtained in the AEV test benches: Class 4 (air permeability); Class 7A (water tightness) and Class C5 (wind resistance).
