Natural Stone Cladding: Anchored In The Past, But Ready For The Future-stone cladding

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.

Üleminek klaasilt tagasi kivile on samuti keskkonnaprobleemide tagajärg. New Yorgi linnapea Bill De Blasio kolis hiljuti elama keelata uued klaasist pilvelõhkujad 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 Itaalia marmor 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.“

Uuenduslikud kattelahendused võimaldavad suuremaid disainivõimalusi | Pildil: Litecore õhukese lõikega Indiana lubjakivi kleepunud alumiiniumist kärgstruktuuriga alusele

Katteinnovatsioonid võivad pakkuda elegantset ja kulutõhusat lahendust loodusliku kivi värvide ja tekstuuride lisamiseks ilma kuluka transpordi ja pika paigaldusega kaasnevate komplikatsioonideta. Looduskivi autentset iseloomu iseloomustades jäävad mõned neist süsteemidest kasutusmugavuse huvides kergeks, muutes selle nutikaks valikuks, et täita rangeid nõudeid, millele arhitektid peavad vastama tänapäevastes ehitusnormides.

Polycori looduslikud kivid sobivad mitmesuguste fassaadide kinnitus- ja tugisüsteemide jaoks. Päritolu on Polycori karjäärid and all through production, the stones are manufactured to each of our partner system’s specifications from ultra-thin profiles up to full thickness dimensional elements complimenting a wide range of facade structures.

Kattekivi valimisel peavad arhitektid kaaluma paljusid tegureid: välimus, kasutusotstarve, projekti suurus, tugevus, vastupidavus ja jõudlus. Valides fassaadide jaoks Polycori kive, saavad arhitektid kasu meie täielikust omandiõigusest tarneahelas alates aluspõhjast kuni paigalduskohani. Polycori taolise ettevõttega töötamise väärtus seisneb selles, et kuna omame oma karjäärid, saame 2–3 keskmise mehe asemel vastata otse kõikidele küsimustele või muredele, mis arhitektil fassaadi spetsifikatsiooni väljatöötamise käigus tekkida võivad.

“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, Hofmanni kivi and others to offer a complete cladding solution for the project.“

Vega on tundnud huvi uuenduslike voodritehnoloogiate vastu ning teinud koostööd meie tootmisettevõtete uurimis- ja arendusekspertidega, et valmistada muutuva paksusega looduskivist vooderdust, mida saab kasutada nii hoone sees kui ka väljaspool. Tavaliselt kinnitatakse see sõltumatu siini ja klambrisüsteemi kaudu.

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, lahendus, mis pakub kivi murdosa kaalust ja paigaldamist kaks korda suurema kiirusega.

3cm stone mechanically anchored to thin, precast concrete panels provides additional installation advantages. Companies such as Hoffman Stone systems are compatible with Polycor’s stones.

Polycoril on oskused luua mis tahes projekte alates lihtsast seinast kuni pinkideni, silmapaistvate arhitektuuriprojektide ja kõrghoonete fuajee interjöörideni. Iga lahendus võimaldab arhitektidel kujundada uuenduslikke, jätkusuutlikke ja esteetiliselt meeldivaid kivipinda sisaldavaid hoonete välisilme.

“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.”

Minevikus ankurdatud, kuid tulevikuks valmis looduslik kivivooder vastab kaasaegse arhitektuuri ja disaini vajadustele. Ja kuigi voodriuuendused muudavad õhukese kivi kasutamise veelgi lihtsamaks kui kunagi varem, ei ole vooderdamine loodusliku kivi ainus tulevik.
