Mark Andol is the owner and founder of General Welding and Fabricating, with locations in Elma and Rochester, N.Y. That business, which manufactured structural and decorative steel components for this store, has been operating since 1989. When the recession hit almost 10 years ago, Andol lost much of his business to companies located overseas, forcing him to cut his workforce to half its size. At that point, he began envisioning a store that would only carry products that are 100 percent American made, to help grow manufacturing within the United States. Andol’s vision became a reality in 2010 when he opened the doors to the first Made in America store in Elma.

Roof Report

The mission of the Made in America Store is to create and save jobs in the United States by increasing American manufacturing. By installing ATAS’ Dutch Seam metal roofing panels, which are made in America, on this new flagship store, it only further reinforced this mission. Dutch Seam, a continuous standing seam metal roof panel, features an integral lock and seam which prevents “blow-off” or “creeping” of the seam. It also eliminates the need for separate seam caps and field seaming.

When ATAS International announced the company’s 2016 Project of the Year winners at an awards banquet on May 8, the Made In America flagship store project took first place in the commercial roofs category.

Accel Roofing Products, a division of ATAS International Inc., has introduced Colonial Seam, a standing seam metal roofing panel.
 
Colonial Seam is a clipless panel that offers a standing seam aesthetic with factory formed advantages.  It is installed by locking the one-piece panel into the previous panel and fastening through pre-punched slots, allowing for expansion and contraction.  All fasteners are concealed by the adjacent panel. The positive locking action makes it virtually impossible for the panels to slide apart.
 
Panels are available in widths of 12-3/8-inches and 16-3/8-inches, with a 1-inch seam height, in .032 aluminum and 24 gauge metallic coated steel.  Both substrates have the same PVDF paint finish in a variety of colors.  Colonial Seam can be installed on any solid surface with a minimum slope of 3:12.  
 
Colonial Seam is a solution to metal roofing for both new construction and re-roofing.  The standing seam panel offers an alternative to other roofing materials.  It provides the benefits of metal roofing with ease of installation, since this is a one-piece panel that does not require the use of clips.
 
Lower energy consumption and reduction in energy bills can be achieved by the use of Colonial Seam.  Depending upon several factors, including the panel color chosen, the slope of the roof, and the location of the building, up to 70 percent of the sun’s energy may be reflected away from the home, minimizing heat retention and keeping the home cooler.

Converting Existing Carports to Solar Carports with Flexible PV Modules

Rooftop solar has become commonplace on commercial buildings and homes. Although a residential home often has sufficient rooftop area to power the home 100 percent with solar, this is not always true with multi-story commercial buildings, apartments and condominiums. The properties often do not have the necessary roof space to offset their energy needs with solar. This situation can also apply to low-rise buildings with high electrical usage, such as factories, big-box stores and warehouses.

The Miasole FLEX Series PV Modules

The Miasole FLEX Series PV Modules

Carports have become a standard feature on many commercial and multifamily properties. Even buildings without carports have parking lots with space for them. Carports provide users the benefit of shading cars and protecting cars and people from rain and snow. Carports keep cars cool, reducing the power required to air condition them when they’re started and reducing sun damage to the car finish. From an environmental standpoint, carports help migrate the heat island effect in which large concrete and asphalt parking lots absorb heat during the day and release the heat at night. This additional heat can drastically change local weather patterns, especially in metropolitan areas.

In recent years, building owners have been installing new carports with solar PV modules. These solar carports have all the benefits of traditional carports with the added advantage of producing clean renewable solar energy while reducing the need to add rooftop solar to buildings.

In many places, existing carports were designed and built with minimal steel support structures and the metal roof and deck panels are already spanning the maximum distance between supports to keep costs down. Most were built to meet the minimum local wind and live-load code requirements. With the cost of solar installations falling, utility energy costs rising and increased interest in improving the environment while reducing a building’s carbon footprint, building owners are interested in retrofitting their existing carports with solar modules. Unfortunately, many of these existing carport structures cannot support the additional 4- to 6-pounds-per-square-foot weight of standard crystalline PV modules and associated racking and rails. The only solution available to the owner is to structurally upgrade the carport or tear it down and replace it with a carport designed for the extra weight of solar. Even if the existing carport structure can support the weight, retrofitting the carport with solar can be technically challenging and expensive.

MiaSolé has developed two solar application solutions to solve the live-load limitations of many existing carports. MiaSolé manufactures a flexible lightweight high-efficiency (16 percent plus) CIGS-based flexible PV module weighing less than 9 ounces per square foot in two format sizes: the narrow-format FLEX-N series designed for traditional architectural standing-seam metal roof panels and the wide-format FLEX-W series. Both can be applied to the carport roof with a simple peel-n-stick adhesive.

Standing-seam Panel

Two roofers can easily apply the FLEX-N series to the existing carport metal panels:

  • Power wash the roof.
  • Wipe down the areas where the FLEX-N modules will be applied with rubbing alcohol.
  • On the standing-seam metal panel (16- to 18-inches wide) lay down the module.
  • One roofer lifts up the module at the j-box end, removes the release film from the adhesive and sets the module down.
  • The second roofer at the other end lifts up and supports the module.
  • The first roofer continues to remove the release film and lays down the module, rubbing the module with his hand to ensure full contact.
  • Once the module is fully adhered, both roofers use a silicone roller to bond the module to the metal pan surface.

Trapezoidal Rib Panel

Although architectural standing-seam panels are frequently used on carports, the 7.2 trapezoidal rib panel is the metal roof industry’s most commonly used corrugated roof panel for carports. Nearly every major metal roof and steel building manufacturer offers a 7.2 rib panel type profile.

The 7.2 corrugated rib panel is economical, strong and aesthetically pleasing while offering excellent spanning and cantilever capabilities, making it an excellent choice for carports and walkway canopies. The 7.2 rib panel with its long-spanning performance helps lower costs by reducing the number of purlins and structural steel needed. The ability to use long metal panels and fastening with exposed fasteners on slopes as low as 1:12 greatly reduces labor costs.

Working with several major metal roof manufacturers such as McElroy Metal and one of the solar carport leading builders, Baja Construction, MiaSolé modified the adhesive patterns on the MiaSolé FLEX-W, the large-format PV module originally designed for low-slope single-ply roofs. The new adhesive pattern makes it simple to bond the MiaSolé Flex-W module directly across the standard 7.2 corrugated rib profile. By eliminating the need for racks and rails, the powerful 360-watt FLEX-W PV module can be rapidly installed by just two roofers over any existing carport or walkway. With a low-slope roof canopy, solar orientation—the direction the carport is facing—is less critical.

Two roofers can easier apply the FLEX-W series to the existing carport metal panels:

  • The existing carport is power washed to remove any dirt and debris from the metal roof surface.
  • Any loose panel fasteners are tightened and missing fasteners replaced.
  • The areas where the FLEX modules are to be installed are cleaned with rubbing alcohol.
  • The FLEX modules are laid down across the corrugated ribs, and the adhesive strips are aligned with the ribs.
  • On one end, the roofer lifts up the module, peels back the adhesive release film, lays the module back down on the 7.2 panel ribs and presses down to bond the module to the ribs.
  • The second roofer on the other end repeats the same process.
  • Both roofers finish bonding the module by rolling the adhesive areas with a silicone roller to ensure complete adhesion to the metal panel.

MiaSolé FLEX series PV modules make it possible to economically convert existing carports with live-load limitations into new solar carports without having to make any major structural modifications. Even on new solar carports, the MiaSolé FLEX series modules can reduce labor and construction cost by reducing the need for heavy steel support structures and allowing longer metal panels with fewer support purlins.

The peel-and-stick adhesive system reduces labor costs while speeding up installation time. Unlike conventional rigid crystalline panels, the flexible MiaSolé FLEX modules work over curved roof structures for solar carports, solar walkways and solar awnings.

MiaSolé and Upland Corp. Enter into Sales Agreement to Sell Thin-film Lightweight Solar Modules

Upland Corp., a manufacturers’ representative firm that provides building material solutions to the commercial construction industries, and MiaSolé have entered into a sales agreement. Upland Corp. will sell MiaSolé FLEX modules in New Mexico and El Paso, Texas, territories. Since 1984, Upland Corp. has helped architects, building owners and contractors by providing quality building solutions to these valued construction partners.

Upland Corp. will engage in the sales and marketing of MiaSolé FLEX modules, efficient thin-film lightweight flexible modules that offer an efficiency rating of more than 16 percent. MiaSolé FLEX modules bond directly to the roof surface with a simple peel-and-stick adhesive. The low-profile FLEX module provides wind resistance and a seismic advantage providing huge benefits over traditional rack-and-panel solar systems.

The FLEX-02 Series module is available in two formats. The FLEX-02W module is 39.3 by 102.3 inches and is rated at 360 watts, and designed for low-slope commercial single-ply roof systems. The FLEX-02N module is 14.6 by 102.3 inches and is rated at 120 watts, and designed specifically for standing-seam metal roofs. The FLEX-02 Series module is IEC 61646 and IEC 61730 and UL 1703 certified.

The FLEX-02 module provides Upland Corp. customers other significant benefits. The low weight of the module (less than 0.7 pounds per square foot) allows installation on roofs that cannot support the weight of traditional glass solar panels. Because the FLEX-02 panels adhere directly to the roof surface, there are no penetrations, eliminating the worry of leakage and damage to valuable contents within the building. The FLEX-02 also is aesthetically pleasing, blending into metal and TPO roofs and preserving the original look of the roof.

Clamp Resists Wind Uplift and Seismic Vibration

A2 AceCamp

Installers of attachment systems on standing-seam metal roofs (SSMR) can now rest assured their roofs will resist wind uplift and seismic vibration with the A2 AceClamp. The A2 AceClamp’s unique design virtually eliminates the need for periodically re-torquing clamps to preserve manufacturers’ warranties, as is recommended for other SSMR clamp systems.

The A2’s innovative solution prevents torque back-out, caused by wind flutter or constant seismic vibration, by employing a distinctive “push-pin” design that locks two stainless steel pins into the roof panel to secure the clamp. The design effectively prevents loosening or torque back-out and is Patent-Applied-For.

Prior to the A2, manufacturers relied on round or concaved-headed set-screws that turned and rotated into the metal roof’s surface to penetrate and lock into the metal seam. This typically resulted in scratches or damage to the panels’ surface. The A2’s sliding push-pin design eliminates this concern. The A2 solution does not damage or scratch the panel surfaces, thus upholding manufacturers’ warranties while assuring one of the strongest clamp systems in the industry.

For solar-racking installations, the A2 saves time and additional costs where grounding cable brackets are used. The A2 is designed with a grounding cable groove in the clamp. A stainless-steel sleeve and set-screw kit securely hold the grounding wire in place. For the installer, this feature eliminates the need for a separate grounding attachment, as the cable groove is incorporated into the clamp itself. The stainless steel sleeve also prevents corrosion of the grounding wire while enhancing electrical conductivity.
