Thermal improvement matters for energy efficiency in both warm and cold climates

SHORE MEM INT NJModel Energy Codes adopted across the U.S. are directing buildings to achieve more efficient performance. Whether trying to keep the warmth inside in cold climates or trying to keep the heat outside in warm climates – Linetec helps optimize aluminum architectural manufacturers’ systems to meet thermal requirements in all climate zones.

Thermal Barriers

Linetec enhances the thermal performance of architectural metal products, such as window, skylight, curtainwall, storefront and entrance systems.

Using a thermal barrier system improves performance by separating the aluminum profile into two parts, while maintaining the structural and long-term durability of the unit. The two methods for doing this are:

While both methods achieve high thermal performance, thermal strut also simplifies dual finishing, where the interior and exterior surfaces may be finished in different colors and formulations.

Curves and Corners

The Exploration Tower at Port Canaveral shimmers with Linetec’s finishing

PortCanaveral3-webExploration Tower at Port Canaveral’s shimmering, iridescent exterior welcomes visitors to Florida’s Space Coast and Canaveral Cove. The seven-story, sail-shaped, metal-clad tower showcases the first use of a mica coating that appears to shift its color in different light and at different angles. Achieving this distinctive effect, Linetec spray-applied Valspar’s Kameleon™ Color to Firestone Metal Products’ UNA-CLAD™ metal wall panels.

Taking its cues from the shapes and hues of the port, GWWO Inc./Architects designed the 23,000-square-foot structure to express the common characteristics of “transience, function and imagery.” GWWO selected Blue Pearl II color-changing paint to capture the themes of revitalization and change it sought to represent for the Port Canaveral area. Along with its unique appearance, Linetec applied the finish in accordance with AAMA-2605 to withstand Florida’s hurricane wind speeds, unrelenting sun and salt spray.

Linetec People to Know – Paul Bratz

Paul Bratz (2)Q: Tell me about your job

A: As Operations Manager my job is very exciting – there is no typical day. There is an element of day-to-day firefighting, but also a concentration on process improvement and planning for the future. Apogee’s guidance on Continuous Improvement and Lean has helped to focus our efforts. Our strong growth over the last few years has been exciting (and challenging) as well.

Q: What did you do prior to Linetec?

A: Prior to Linetec I worked at American Wood Fibers in Schofield, Wisconsin. American Wood Fibers manufactures pet bedding from compressed bales of wood shavings, and wood flour that’s used primarily as a filler in plastics and adhesives. It’s an interesting process where wood waste from several of the door and window manufacturers in the area (many of which are Linetec customers) is processed into these useful items rather than landfilled or used as boiler fuel.

Q: What is your favorite part of your job?

A: The best part of my job is working with a wide variety of people in different capacities throughout the organization. I also enjoy working for a company with a track record of success and growth. Our culture and core values are one of the differentiators – they help make the tough days worth it.

Q: What poses the biggest challenges for you?

A: At the current time, labor availability is the largest challenge. We’re enjoying a strong economy today. Many businesses in our local community are hiring. To recruit and hire high-caliber people, we have to set a high standard and promote our strengths – culture, safety, stability and environmental responsibility.

Q: Are there any finishing type or color trends that you seeing more of lately?

A: White colors seem to be trending up at the current time. A few years ago, the trend was aluminum-flaked metallic colors with clear coats, but this has migrated more recently to mica-flaked “metallic” coatings without the need of clear top coats. Mica coatings are less sensitive than metallic’s to the flake orientation dynamics, helping to minimize the risk of metallic variation.

PaulBratz-flambeauQ: What is something you are looking forward to?

A: I’m looking forward to summer activities. Golfing, biking, fishing and grilling out with friends are some of my favorites.

Q: What is something people don’t know about you?

A: Outside of work, I enjoy bicycling. I’m not a particularly gifted or fast rider, but I enjoy endurance riding. We have a local 24-hour mountain bike race that I usually participate in and I also do several rides of 100 miles or more each summer. I find cycling to be a great way to relax and enjoy time with friends, particularly when it involves a cold beer after long ride.

San Francisco International Airport’s new air traffic control tower meets high-performance design and LEED Gold criteria features Wausau’s curtainwall, Tubelite entrances, finishing by Linetec


San Francisco International Airport (SFO) and the Federal Aviation Administration’s (FAA’s) first-of-its-kind airport traffic control tower and integrated facility features high-performance finishes by Linetec on architectural aluminum products by Tubelite Inc. and Wausau Window and Wall Systems.

Designed-Built to Multi-Performance Requirements

 The new $80 million, 221-foot-tall, torch-shaped tower offers improved safety, security and design standards, and has obtained LEED® Gold status. The seismic design for the tower allows for the structure to withstand a Richter magnitude 8 earthquake.

SFO’s previous air traffic control tower was built in 1984. The new tower and integrated facility’s conceptual design was created by airport master architecture firm HNTB. Fentress Architects served as architect-of-record and Hensel Phelps led the design-build team. The collaborative approach resulted in a distinctive design that is seismically sound and meets the FAA’s strict requirements.

The “cab” at the top of the tower features a cantilevered roof and windows to give controllers an unobstructed view of the airfield below. The tower façade consists of curved metal panels and a vertical glass band that is illuminated to colorfully glow at night.

The base of the new SFO tower includes a corridor and a secure connector between Terminals 1 and 2, a new FAA office space, and improvements to the Terminal 1 Boarding Area C entrance. The corridor offers a unique glass skylight, which provides visitors views directly up the full height of the tower. The secure connector bridge also offers unobstructed views of the runways, a rest area with seating, and an adjoining yoga room.

Construction began in summer 2012, was ready for FAA equipment installation in summer 2015 and opened in autumn 2016. Construction manager, T2 Partners, selected Architectural Glass & Aluminum (AGA) as the glazing contractor. AGA relied on Wausau, Tubelite and Linetec to meet the aesthetic, acoustic, blast hazard mitigating (BHM), seismic, thermal and other performance specifications of SFO’s unique facility.

Durable Finishes for LEED Gold Sustainability

Contributing to the project’s sustainability goals, the aluminum used to produce Wausau’s curtainwall and window systems is a high recycled-content aluminum billet composition with durable finishes by Linetec.

As a recognized, environmentally responsible finisher, Linetec 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.

For the new SFO facility, Linetec applied a Duranar® Sunstorm® Galaxy Silver color, 50 percent polyvinylidene fluoride (PVDF) resin based, two-coat, liquid coating on the interior-facing aluminum framing members. For greater protection on the exterior, weather-exposed surfaces, a three-coat Duranar Sunstorm XL Silver color, 70 percent PVDF liquid coating was applied. Applied under Linetec’s stringent factory-controlled processes, these finishes meet the American Architectural Manufacturers Association’s (AAMA) 2605 industry standards, as well as minimize buildings’ maintenance costs and maximize long lifecycles.

Along with sustainably produced finish materials and natural daylight, the SFO facility’s other LEED-recognized features include photovoltaic panels, a roof garden, low-flow plumbing fixtures, energy-efficient HVAC systems, programmable LED lighting and electric vehicle charging stations.

“Whether building a new structure or replacing, renovating and modernizing an existing facility, Tubelite’s and Wausau’s high-performance systems, and Linetec’s finishing services, help design-build teams to create elegant, daylight-filled, energy-efficient and safe buildings,” says Tubelite’s product manager, Tom Mifflin. “Creating a comfortable, quiet environment promotes concentration and productivity, which is essential to air traffic control.”

Proven Safety and Security

 AGA installed more than 4,000 square feet of Wausau’s four-sided, silicone-glazed curtainwall including SuperWall8250 Series curtainwall, INvision 7250-UW Series unitized curtainwall and 7250 Series BHM curtainwall, plus INvent 3250i Series in-swing casement thermal windows.

In addition, AGA installed Tubelite Inc.’s ForceFront Blast entrance systems. All of Wausau’s BHM Series products and Tubelite’s ForceFront Blast products are designed for compliance with the General Services Administration Inter-Agency Security Committee’s (GSA ISC) security design criteria and the Department of Defense United Facilities Criteria (DoD UFC) 4-010-01 requirements.

“As doors, windows and curtainwall encounter the extreme pressures released by an explosive mass, all elements of the assembly work together to withstand the blast load and dissipate its energy. Instead of the historical design practice of specifying thick windows with rigid frames, modern blast-mitigating assemblies are designed to be flexible, and absorb, rather than resist, blast energy,” explains Mifflin.

Drawing from more than a decade of experience on dozens of major BHM projects, the associates at Tubelite and Wausau apply their technical expertise to interpret the lexicon of hazard mitigation and to achieve safety, security, cost effectiveness and timely completion.

Efficient Service and Growth

SFO offers non-stop flights to more than 45 international cities on 39 international carriers. The Bay Area’s largest airport connects non-stop with 78 cities in the U.S. on 13 domestic airlines. During its 2015-16 fiscal year, it set an all-time traffic record of serving more than 51.4 million passengers.

“Our goal is to be an exceptional airport, in service to our communities,” stated airport director Ivar C. Satero. “Looking ahead, our focus is on the ongoing development of our airport infrastructure, to ensure that SFO can grow efficiently and continue to make a positive economic contribution in the Bay Area.”

Choosing architectural painted coatings – 70% PVDF, 50% PVDF, Baked Enamel – What’s the difference?

man hands on window frameWhen selecting high-performance architectural coatings for aluminum building products including window, curtainwall, storefront, entrance and panel systems – there are three main choices for durable painted finishes: 70% PVDF, 50% PVDF and baked enamel.

70% PVDF resin-based coatings offer the ultimate protection in building performance.

No other coating system can withstand the rigors of nature and time like those based on the polyvinylidene fluoride (PVDF) resin, such as Kynar 500® or Hylar 5000®. The resin system determines the properties and performance of the paint. In a 70% PVDF coating, 70% of the resin component is PVDF.

Ideal for high-performance exterior-facing building products, 70% PVDF resin-based coatings meet the industry’s stringent requirements set by the American Architectural Manufacturers Association – AAMA 2605. They exhibit outstanding resistance to humidity, color change, chalk, gloss loss and chemicals to ensure a long lasting, durable finish.

Linetec-paint-chips-(9)-web-smallerAmong the most popular and reliable 70% PVDF resin-based coating families are:

  • AkzoNobel TRINAR®
  • Valspar Fluropon®
  • Sherwin-Williams SHER-NAR®

50% PVDF resin-based coatings offer an intermediate level of exterior protection.

Architectural painted finishes with 50% PVDF resin-based coatings that meet the AAMA 2604 specification provide good color and gloss retention in exterior applications. These coatings also offer good hardness and abrasion resistance, making it a frequent choice for storefront, doors, or other high-traffic areas.

Among the most popular and reliable 50% PVDF resin-based coatings are:

  • AkzoNobel ALUM*A*STAR® and ALUM*A*Escent®
  • Valspar Acroflur®

Baked enamel coatings offer a lower level of protection, typically for interior metal products.
Baked enamel finishes are acrylic/polyester coatings. Meeting the AAMA 2603 specification, the coatings are a one-coat system with poor resistance to color fading and chalking. For these reasons, they typically are used for interior applications where color retention, chalk, fade and weatherability is not required.

Among the most popular and reliable baked enamel coatings are:

  • AkzoNobel ACRA-BOND® ULTRA
  • Valspar Flurocryl
