Natursteinsbekledning: forankret i fortiden, men klar for fremtiden - steinkledd

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.

Overgangen fra glass tilbake til stein er også et resultat av miljøhensyn. New York City-ordfører Bill De Blasio flyttet nylig til forby nye glassskyskrapere 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 Italiensk marmor doesn’t cut it anymore.

I FORANEN AV INNOVASJON AV NATURSTEINKLEDNING

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.“

Kledningsinnovasjoner kan tilby en elegant og kostnadseffektiv løsning for å inkludere fargene og teksturene til naturstein uten komplikasjoner med kostbar transport og langvarig installasjon. Mens de personifiserer natursteinens autentiske karakter, forblir noen av disse systemene lette for enkel bruk, noe som gjør det til et smart valg for å møte de strenge kravene som arkitekter må oppfylle i moderne byggeforskrifter.

Polycor natursteiner er anvendelige for en rekke fasadeforankrings- og støttesystemer. Opprinnelse ved Polycor steinbrudd 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.

Når du velger en stein for kledning, må arkitekter veie mange faktorer: utseende, tiltenkt bruk, størrelsen på prosjektet, styrke, holdbarhet og ytelse. Ved å velge Polycor-stein til fasader drar arkitekter nytte av vårt fulle eierskap til forsyningskjeden, fra helt ned i berggrunnen til monteringspunktet. Verdien av å jobbe med et selskap som Polycor er at siden vi eier steinbruddene våre, kan vi svare direkte på alle spørsmål eller bekymringer en arkitekt måtte ha under prosessen med å utvikle en spesifikasjon for en fasade i stedet for å ha 2-3 mellommenn.

“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 stein and others to offer a complete cladding solution for the project.“

Vega har vært interessert i innovative kledningsteknologier og samarbeidet med forsknings- og utviklingseksperter ved våre produksjonsanlegg for å lage natursteinskledning av variabel tykkelse som kan brukes enten inne i eller utenfor en bygning. Den er vanligvis festet via et uavhengig skinne- og klemsystem.

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, en løsning som tilbyr stein til en brøkdel av vekten og installasjon med dobbel hastighet.

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.

Polycor har ekspertisen til å lage ethvert prosjekt fra en enkel vegg til benker, fremragende arkitektoniske prosjekter og høyhusinteriør. Hver løsning gjør det mulig for arkitekter å designe innovative, bærekraftige og estetisk tiltalende eksteriør av bygninger med steinoverflater.

“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.”
