天然石材覆層：立足於過去，但為未來做好準備-石材覆層

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.

從玻璃回到石頭的轉變也是環境問題的結果。紐約市長比爾白思豪 (Bill De Blasio) 最近搬到 禁止新玻璃摩天大樓 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 義大利大理石 doesn’t cut it anymore.

處於天然石材覆層創新的前沿

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.“

包層創新可以提供優雅且經濟高效的解決方案，將天然石材的顏色和紋理融入其中，而無需經歷昂貴的運輸和漫長的安裝的複雜性。在體現天然石材的真正特徵的同時，其中一些系統仍然輕巧，易於使用，使其成為滿足建築師在現代建築規範中必須滿足的嚴格要求的明智選擇。

Polycor 天然石材適用於各種外牆錨固和支撐系統。起源於 Polycor 採石場 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.

在選擇用於包層的石材時，建築師需要權衡許多因素：外觀、預期用途、項目規模、強度、耐用性和性能。透過選擇 Polycor 石材作為外牆，建築師可以從我們對供應鏈的完全所有權中受益，從基岩一直到安裝點。與Polycor 這樣的公司合作的價值在於，由於我們擁有自己的採石場，因此我們可以直接回答建築師在製定立面規範的過程中可能遇到的任何問題或疑慮，而不需要2-3 個中間人。

“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 埃克拉德， 霍夫曼石 and others to offer a complete cladding solution for the project.“

Vega 一直對創新包層技術感興趣，並與我們製造工廠的研發專家合作，製造出可在建築物內部或外部使用的不同厚度的天然石材包層。它通常透過獨立的導軌和夾具系統固定。

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，一種解決方案，提供的石材重量僅為其一小部分，安裝速度卻是原來的兩倍。

Polycor 擁有創建任何項目的專業知識，從簡單的牆壁到長凳、傑出的建築項目和高層大廳內部。每個解決方案都允許建築師設計出結合石材表面的創新、可持續且美觀的建築外觀。

“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.”
