Nash Women’s Center

The classic beauty of copper brings a rich distinction to architectural building projects – whether creating a dramatic new design, or conveying a historic depth and heritage. Today, you can achieve the look of real copper and lasting luster, without such shortcomings as salt run-off stains, galvanic corrosion, patina and intensive maintenance.

Nash_1617-lLinetec’s exclusive copper color anodize expands the typically limited color choices of anodize, while delivering the highest performance available. This proprietary, consistent, repeatable and warrantied finish is accomplished through a three-step electrolytic coloring method, rather than the standard two-step process. Material is anodized and then introduced into two separate coloring tanks where elemental metals are placed into the pores of the anodic coating. The first color tank contains tin, and the second color tank contains copper. Isolating the actual copper in the coating results in a striking visual effect that will remain stable to provide many years of low-maintenance service.

Nash_1522-lMany factors can affect the color and/or shade, in the copper anodize process, and should be taken into consideration when considering copper anodize. Four different lots of raw aluminum were used to create the extreme color range of copper anodize on Dri-Design’s wall panel system for Nash Women’s Center in Rock Mount, North Carolina.

Linetec’s copper anodize finish:

  • Appears as a bright copper color, with no patina over time
  • Does not require a clear coat or ongoing treatment to maintain color stability
  • Produces no harmful or dangerous by-products and is non-hazardous
  • Meets AAMA 611 Class I Specification
  • Is available for extrusion, stretch-formed and flat sheet aluminum
  • May be finished before or after assembly
  • Weighs less than half that of real copper, for easier transportation and installation
  • Can be designed adjacent to other aluminum materials, without galvanic corrosion risk
  • Will not leave copper run-off stains on a building’s exterior
  • Protects and maintains the structural integrity of the the aluminum
  • Retains exceptional hardness and lasting durability
  • Warrantied for five years, the same as our other Class I anodize finishing

Nash_1643-lAnodized aluminum resists the ravages of time, temperature, corrosion, humidity and warping, for a long product life cycle. Your copper anodize aluminum also may be specified with recycled content and is 100 percent recyclable.

Tackling a transportation center or high-traffic, urban project? Consider corrosion-resistant finishes

Transportation facilities, transit oriented developments and other high-traffic city centers provide the connecting points and places that compose our urban landscapes and skylines. They also can present significant challenges in protecting exterior-facing architectural aluminum products. Without proper precautions and finishes, corrosion to finished aluminum components ultimately can damage the structural integrity of the building envelope and can lead to systemic failure.

 

Windows, storefronts, entrances and curtainwalls, sun shades, canopies, skylights, column covers, rain screens and exterior panels all commonly are manufactured from aluminum and integrally connect to a building’s façade. In almost any city, these architectural aluminum products are continually exposed to not only weathering, but to pollution and chemicals, as well as bumps and scuffs of pedestrians. While salt spray performance considerations usually are reserved for coastal conditions, it’s important to remember that salt mixture often is used to de-ice roads making it an equal concern in colder climates.

As a prominent part of the building’s exterior, the finished aluminum adds color and design to the project; this coating also protects the building from unsympathetic surroundings. The American Architectural Manufacturers Association (AAMA) continues to set the highest standard for architectural finishes, especially in highly corrosive environments. When selecting a coating that will be required to withstand such conditions, select either the highest-performing organic paint coating that meets the AAMA 2605 specification, or a Class I anodize that meets AAMA 611.

Orlando-_-ITF-webHigh-Performance Painted Coatings

High-performance, 70 percent polyvinylidene fluoride (PVDF) resin-based coatings give architects, specifiers and building owners the capability to select nearly any conceivable color or combination of colors, while shielding the building against weathering, pollution and aging.

PVDF is known for its exceptional chemical stability and excellent resistance to ultraviolet (UV) radiation. It is used in architectural applications as a coating on aluminum where it provides exceptional resistance to environmental exposure.

The carbon-fluorine bond, used in the 70 percent PVDF, including Kynar® 500 resin-based architectural coatings, is one of the strongest bonds known. These paint coatings can withstand enduring and intense UV radiation. Such attributes support long-term color- and gloss-retention, and chalk-resistance.

 

These highest-performing 70 percent PVDF coatings meet the most stringent, exterior, architectural specification AAMA 2605, “Voluntary Specification for High Performance Organic Coatings on Architectural Extrusions and Panels.” This specification requires paint coatings to meet rigorous testing performance standards including more than 4,000 hours of salt spray, and heat- and humidity-resistance.

Protean - Cedar Grove TransitCorrosion-Resistant Requirements

Section 8.8 of AAMA 2605 refers to the corrosion resistance requirements of all coatings that must pass these stringent guidelines:

  • Humidity –The sample is exposed in a controlled heat and humidity cabinet for more than 4,000 hours at 100 degrees Fahrenheit and 100 percent relative humidity. No formation of blisters to extent greater than “few” blisters, as defined by ASTM D714.
  • Cyclic corrosion testing (previous referred to as salt spray resistance) – Score the film sufficiently deep to expose the base metal. Expose the sample for 2,000 hours according to ASTM G85, Annex A5, dilute electrolyte cyclic fog/dry test. The sample must score a minimum rating of 7 on scribe or cut edges and a minimum blister rating of 8 within the test specimen field, as defined in ASTM1654.
  • South Florida exposure – The coating shall maintain its film integrity, color retention, chalk resistance, gloss retention and erosion resistance properties for a minimum of 10 years on the south Florida on-fence testing site.
  • Color retention – Maximum of 5ΔE Units (Hunter) of color change after the minimum 10-year exposure test. A ΔE unit is the variance or color difference measured on a vector scale from a specific point in the color space.
  • Cedar Avenue Transit Station-1 399X440 Duranar MICAChalk resistance – Chalking shall be no more than that represented by a No. 8 rating for colors and No. 6 for whites after 10 years of test fence exposure. Per ASTM D4214, chalking is measured on a numerical scale with higher numbers representing better chalk resistance.
  • Gloss retention – Gloss retention shall be a minimum of 50 percent after the 10-year exposure testing, as described by ASTM D 523.
  • Resistance to erosion – Less than 10 percent film loss after the 10-year exposure testing
  • AAMA notes that high humidity environments such as, but not limited to, seacoast or industrial environments, performance of corrosion resistance may be diminished.

High-Performance Anodize Finishes

 

Class I anodize finishes that meet or exceed all requirements of AAMA 611 “Voluntary Specification for Anodized Architectural Aluminum” also resist the ravages of time, temperature, corrosion, humidity and warping. Anodized aluminum withstands extreme temperature changes and weather conditions, constant exposure to vehicle exhaust, and daily use by passengers. Over-sprayed salt de-icing can be managed with a simple rinsing as needed. With basic cleaning and maintenance, architectural aluminum products enjoy a long life cycle.

Metro shelte3The anodizing process, because it is an integral part of the substrate, produces an oxide film that is uniform, hard and protects the rest of the aluminum substrate from deterioration – providing excellent wear and abrasion resistance. The coating produced is extremely durable, and the hardness of the surface is comparable to a sapphire—the second hardest substance on earth. This characteristic makes anodize an ideal choice for use in high-traffic areas where resistance properties are important.

In the most challenging applications, anodize aluminum will perform as specified and will not reduce the service life of the aluminum, but may affect the natural beauty of the surface finish. Avoid any conditions that quickly can corrode an anodize finish such as mortar, cement and other alkaline materials.

To meet AAMA 611 requirements, Class I anodize must have a dry film minimum thickness of 0.7 mils to pass these stringent guidelines:

  • Abrasion Resistance (Michael Clarke Test) – A go/no-go abrasion test using abrasive papers coated with silicon carbide, garnet and glass, respectively. This is used to discriminate between films of the correct hardness and those that may give poor service because they are too soft. The specification grade of abrasive paper is Abrasive Type: Glass, Grade: “Flour,” Mohs’ Hardness Scale Number: 4.5-5.5.
  • Corrosion Resistance testing (previous referred to as salt spray resistance) –Expose the sample for 3,000 hours according to ASTM B117 using 5 percent salt solution. Test samples shall show no more than a total of 15 isolated spots or pits none larger than 1 mm in diameter, in a total of 381 cm of test area grouped from five or more test pieces.
  • South Florida exposure – The coating shall maintain its color retention, gloss retention and erosion resistance properties for a minimum of 10 years on the south Florida on-fence testing site.
  • Color retention – Maximum of 5ΔE Units (Hunter) of color change after the minimum 10-year exposure test.
  • Gloss retention – Gloss uniformity shall be within established gloss range.

 Durability and Sustainability

TForge_018-webAnodized aluminum is an inert, non-combustible material that is 100 percent recyclable and poses no health risks. At the beginning of the new millennium, Linetec and other environmentally responsible finishers, changed from the traditional caustic etching process to a more eco-friendly etch system allowing customers to use secondary (recycled) billet in the anodize process.

Small surface defects, such as those common in recycled material, are hidden by the eco-friendly anodize finish’s “frosty” matte appearance. Architects prefer the aesthetic of this matte finish. The resulting surface also reduces glare in bright sunlight. Gloss level reading is typically reduced from 15 to 25 with conventional anodize, down to a gloss level of 3 to 12 for eco-friendly color anodize.

The eco-friendly anodize process reduces landfill waste used with conventional etch processes by 75-80 percent. Landfill waste directly relates to the production of greenhouse gas. It also has the viscosity of water and will not collect in the small recesses of aluminum extrusions or narrow aluminum tubes, which enhances the durability and lifecycle of the finished architectural aluminum product.

cedar-ave-transit-berg-170607-8198-o.jpgFor painted architectural aluminum products, Linetec and the leading paint manufacturers recommend the use of a PVDF-based paint system on aluminum material for all corrosive environments. Offering the longest lifecycle, a 70 percent PVDF resin-based coating system, pretreated with chrome phosphate, along with an inhibitive chrome-rich primer should be used. This coating type meets or exceeds all the requirements of AAMA 2605.

Beyond ensuring the highest quality application, Linetec also is recognized as an industry-leading environmentally responsible finisher. It also captures the liquid paints’ volatile organic compounds (VOCs) content using a 100 percent air capture system and safely destroys the VOCs with a regenerative thermal oxidizer. Linetec then re-uses its heat energy byproduct to improve process energy efficiency. This process of re-use is completed before the material exits the paint line.

Ace Hotel Chicago showcases windows finished by Linetec

Architectural Record  recently published an article on the industrially inspired Ace Hotel Chicago in the Fulton Market area, a 10-minute walk to the city’s downtown Loop. Designed by GREC Architects, the $44 million, 159-room hospitality destination features products from Winco Windows and from Wausau Window and Wall Systems, both finished by Linetec.

The window systems chosen for the new hotel match the Chicago, industrial aesthetic of the historic Landmark District. Linetec finished the aluminum-framed openings to be reminescent of old steel-framed factory windows. Apart from its classic appearance, the street-side façade showcases a graphic grid of modern, high-performance, floor-to-ceiling window units.

On the first floor, Winco’s windows are painted in a black Duranar® coating. Above these, Linetec finished Wausau’s window systems in a combination of clear Class II anodize on the interior surface and an exterior Wrought Iron color using Valspar’s Fluropon® coating system. Both Duranar and Fluropon are 70 percent PVDF resin based coating, which are applied by Linetec to meet or exceed the American Architectural Manufacturers Association’s high-performance exterior specification, AAMA 2605. These painted finishes exhibit outstanding resistance to humidity, color change, chalk, gloss loss and chemicals, ensuring a long-lasting, durable finish with minimal maintenance.

Along with contributing to the windows’ aesthetics and durability, Linetec also improved the thermal performance on Wausau’s painted, aluminum framing members. Adding insulating, thermal, polyamide strut separates the inside and outside metal, which greatly enhances the window system’s thermal performance. This thermal break reduces the amount of heat transfer, therefore saving energy and increasing the hotel guests’ comfort.

Opened in August 2017, Ace Hotel Chicago is situated directly across the street from Google, which included a clause in its lease that stipulated the construction of a hotel. Ace was selected in part because of its track record transforming emerging neighborhoods.

According to the article, the architectural vision was inspired largely by neighboring buildings designed by Mies van der Rohe. Ace’s chief brand officer, Kelly Sawdon, called it “a modern synthesis of functionality, art and design in the legacy and spirit of Chicago.”

A Portland-based boutique hospitality chain, Ace has established its brand primarily through edgy makeovers of historic buildings such as Ace Hotel New Orleans. The Chicago hotel is only its second property brought to market with mostly new construction.

The Chicago project’s numerous challenges included a height limit on most of the building, an historic Landmark District designation for the two-story red brick façade of a former cheese warehouse, and a regulation requiring a continuous street wall. Addressing all of these aspects, the architects created a hybrid building designed to look like three smaller ones:

  • At one end, a four-story structure was constructed behind the historic façade and clad in matching red brick.
  • At the other end, a seven-story structure was built with meeting rooms, a bar and lounges on the top two floors. Both of these wings have retail space at streetlevel and guest rooms above.
  • In between, the architects inserted a 163-foot-long, four-story span topped by a roof terrace containing the hotel lobby and public spaces.
