Harri naturala estaldura: Iraganean ainguratuta, baina etorkizunerako prest harriz estalita

The longevity of stone puts any human concept of old age to shame. Stone creates a sense of permanence and solidity, even when worn and weathered. It’s been used throughout history as the structure and facade of buildings- buildings that have literally stood the test of time.

While natural stone has been the material of choice for millennia, glass has dominated commercial construction—especially large scale projects like skyscrapers—in recent years. But architects are increasingly reacting to this glut of glass by returning to stone for their projects. For many developers and architects, glass had become the default, a sterile, too obvious choice which resulted in a flat, texture-less and uninspired design.

Beiratik harrirako trantsizioa ere ingurumen-kezkaren ondorioa da. Bill De Blasio New Yorkeko alkatea duela gutxi joan zen bizitzera beirazko etxe orratz berriak debekatu in the city, making New York the first city to mandate energy efficiency. But it won’t be the last: According to the United Nations, 40% of the world’s energy consumption can be attributed to buildings. Pressure to construct buildings in a sustainably responsible manner is being felt by developers and architects around the world.

“It’s pretty well known in the industry that those glass facade buildings are not energy efficient,” said Hugo Vega, vice president of Architectural Sales at Polycor. “Meaning that in the summer it becomes super hot and you need to have an extensive system of air conditioning and in the winter you need a lot of heating as compared to a traditional building with more stone.”

The design community has been embracing stone for facade design instead, and just in time, as changes in building codes and regulations are set to further tighten architects’ design choices. Natural stone plays an important role in the future of sustainable architecture thanks to its life-cycle, durability, ease of care, low maintenance, and energy efficiency— the list goes on. The minimal environmental impact that innovative cladding wall systems provide is another reason the building industry is moving back to natural materials.

“Energy inefficient glass facades concerns are a good driver for the growing popularity of stone cladding,” said Vega.

Vega understands this continued demand for stone cladding better than just about anyone: he’s been the driving force behind the development of the cladding division of Polycor and he has an in-depth understanding of what architects and builders are looking for in their products.

“The type of stone will dictate possible finishes, thickness, and more,” said Vega. “For example, it’s inadvisable to use polished 3cm marble and expose it to the elements for cladding. Direct communication with selected quarries will help validate the block sizes and thus the maximum finished panel sizes, what natural features can be expected in the stone, and the availability of the material according to job size and phases.” Specification challenges can present themselves throughout a project, such as alternate stones being introduced by other parties and detracting from the initial design intent. Maintaining a close contact with the quarry teams helps ensure this is preserved. As Hugo points out, “Make sure to specify the true, branded names of the materials to avoid being supplied with undesired alternates.” The old days of calling out Italiako marmola doesn’t cut it anymore.

Stone cladding isn’t just the smart alternative to energy efficient glass, it’s also the simple choice, thanks to new cladding attachment systems.

“These new attachment systems allow stone to be used for lighter applications, when the structure has not been designed for a heavy full bed,” said Vega. “They also allow for a faster installation compared to traditional methods.“

Estaldura-soluzio berritzaileek diseinu-aukera handiagoak ahalbidetzen dituzte | Irudian: Litecore Indiana Limestone ebaki mehea aluminiozko abaraska euskarriari atxikita

Estalduraren berrikuntzek soluzio dotore eta errentagarria eskain dezakete harri naturalaren koloreak eta ehundurak txertatzeko garraio garestia eta instalazio luzearen konplikaziorik gabe. Harri naturalaren benetako izaera pertsonifikatzen duten bitartean, sistema horietako batzuk arin mantentzen dira erabiltzeko erraztasunerako, eta aukera egokia da arkitektoek eraikuntza-kode modernoetan bete behar dituzten baldintza zorrotzei erantzuteko.

Estaldurarako harria aukeratzerakoan, arkitektoek faktore asko neurtu behar dituzte: itxura, aurreikusitako erabilera, proiektuaren tamaina, indarra, iraunkortasuna eta errendimendua. Fatxadetarako Polycor harriak aukeratzean, arkitektoek hornikuntza-katearen jabetza osoaz baliatzen dira, hondoan behera, instalazio-punturaino. Polycor bezalako enpresa batekin lan egitearen balioa da gure harrobien jabeak garenez, arkitekto batek izan ditzakeen galdera edo kezkei zuzenean erantzun diezaiekegula fatxada baten zehaztapena garatzeko prozesuan, 2-3 bitarteko gizon izan beharrean.

“We have a wide array of our own limestone, granite and marble, so architects can discuss with the source and get accurate and reliable information,” said Vega. “We fabricate ourselves and sell blocks to other fabricators, ensuring competitiveness of the offers, while preserving the design intent. We work with industry leaders like Eclad, Hofmann Harria and others to offer a complete cladding solution for the project.“

Vega-k estaldura-teknologia berritzaileetan interesa izan du eta gure fabrikazio-plantetan ikerketa eta garapeneko adituekin lan egin du, eraikin baten barruan zein kanpoan erabil daitezkeen lodiera aldakorreko harri natural-estaldurak egiteko.

Polycor’s stone veneer can be installed over solid facing, which eliminates the challenge of removing the original substructure in some cases. Some stone panels are cut thin, while still maintaining the authentic look and feel of a thicker stone without the heavy weight of a 3-6 inch deep stone veneer, making installation fast and simple. Polycor’s thin stones are compatible in many cladding configurations and are manufactured for systems like Litecore, harria pisuaren zati batean eta abiadura bikoitzan instalatzen duen irtenbidea.

Soluzio bakoitzari esker, arkitektoek harrizko gainazalak dituzten eraikinen kanpoalde berritzaileak, jasangarriak eta estetikoki atseginak diseina ditzakete.

“These solutions can also be used interchangeably to blend with more traditional architectural elements and stone masonry construction such as full bed trim, cornices, lintels and things of that nature,” said Vega. “And again, once the material is specified, it can be used on any cladding system, traditional masonry and fabricated by pretty much all the fabricators operating on the market today. This way architects can lock in their design intent, and let engineers and builders establish means and methods to realize the design within budget.”
