When a warehouse at the Komatsu manufacturing complex in Longview, Texas, sustained extensive tornado damage, the company decided to build a new, state-of-the-art warehouse in its place.

Komatsu turned to a trusted business partner, Transet Co., a Longview-based design-build contractor, to demolish the old structure and construct its 81,438-square-foot replacement. The new warehouse features insulated metal panels (IMPs) from Metl-Span in both the roof and wall systems, as well as a permanent rooftop walkway system from LMCurbs, which was installed to facilitate ongoing maintenance of the rooftop HVAC units.

According to Dale Pickard, project manager for Transet Co., the IMPs not only made for smooth construction, but they helped the warehouse meet building envelope energy requirements.

Challenges on the project included a tight schedule, unseasonably rainy weather and accommodating nearby manufacturing facilities that were continuously operational.

The LMCurbs Roofwalk System was installed to facilitate ongoing maintenance of the rooftop HVAC units and protect the roof.

The scope of work included the removal of the previous structure and subgrade remediation. After the footings and slab were in place, the Pre-Engineered Metal Building (PEMB) was erected. The system was supplied by Houston-based Mid-West Steel Building Co. and erected by Cannon Steel Erection Co., located in Tyler, Texas.

After the metal frame and roof purlins were in place, Cannon Steel Erection installed the IMPs to complete the wall and roof systems. “You basically go in sequence from left to right with the IMP roofing panels,” Pickard explains. “You just start at one end, work to the other end, and then come back and install the panels on the other side. It’s basically a straight line process from one end to the other.”

The roofing panels were 42 inches wide and 4 1/2 inches thick and incorporated a standing seam. “The panels attach at the purlin with a concealed fastener clip,” says Pickard. “The IMP has a finished skin on the upper and lower sides.”

The seams were hand crimped and then mechanically seamed. At the eave, a gutter system was installed after the roof and wall panels were tied in together.

Workers on the roof were tied off with personal fall arrest systems and retractable lifelines attached to non-penetrating temporary anchor points. “All facets of construction safety were of paramount importance to Transet Co.,” Pickard states. “Safety was and is the first order of business for everybody.”

Completing the Roof Installation

The roof system features Kingspan skylights, which were installed using custom curbs supplied by LMCurbs, headquartered in Longview, Texas. LMCurbs also supplied curbs for the HVAC units, as well as the rooftop walkway system.

The LMCurbs Roofwalk System was installed using H90 clamps from S-5!

The walkway was installed after all of the HVAC equipment was in place and the roof system was completed. The LMCurbs Roofwalk System was designed to provide a safe way to access HVAC equipment while protecting the roof. “It’s basically a roof access area for the maintenance personnel to enter,” Pickard says. “It’s a railed walkway gated at one corner of the building for access, and it goes to each one of the rooftop units (RTUs). In all, there is more than 1,400 linear feet of walkway.”

The system was mounted using S-5! H90 clamps. “There were no penetrations in the roof,” Pickard points out. “It’s a durable system that will protect the owner’s investment in the roof.”

According to Aaron Combs, product manager at LMCurbs, the project was one of the first to use the company’s redesigned LMCurbs Roofwalk System with upgraded handrails. “It was designed to be both a better looking, more professional end product for the building owner, and a more user-friendly system for the installers in the field,” Combs says. “The new handrail assembly utilizes Speed-Rail fitting by Hollaender and is now down to four pieces — from 28— so the number of man-hours needed to install the system is drastically reduced. It also streamlined the warehousing and distribution process because the redesigned support plates eliminated multiple manufacturing processes. With this redesign and stackable plates, we are able to maintain better stocking levels and provide our customers with a faster shipping timeframe.”

Field installations often present unique and unforeseen obstacles. On this project, when the location of some HVAC units was adjusted from the initial layout, Combs was ready to help ensure the walkway would be installed correctly. “We are always available to offer advice and technical support, and that can be especially important with a first-time installer,” Combs says. “They can contact us any time and we can help walk them through it and assist with any issues that might arise.”

Work began in April 2019 and wrapped up February 2020. “We had a wet start, which made soil remediation difficult,” notes Pickard. “In the latter part of our project, we had an extremely wet January and February, and that presented challenges in erection and finish out. Despite the bad weather, the building came together ahead of schedule.”

Coordinating all phases of the project at an active manufacturing campus also posed some logistical hurdles. “The existing plant, of course, was in operation the entire time,” recalls Pickard. “The site where the new warehouse was being built was where the old warehouse facility was, and the existing loading dock had to remain in operation until they were in the new building. That encroached on the footprint of the new facility.”

Final touches included new loading docks, interior offices and restrooms. “This project shows our ability to deliver an outcome that meets the client’s needs from design to finished product — safely, under budget, and ahead of schedule,” notes Pickard.

“It demonstrates our ability to provide a first-class warehouse facility for the owner. We’ve been doing it a long time. Our company has been in business for 38 years. We are a safety-oriented company with vast experience in most phases of commercial, industrial, and institutional construction, and we are there for our customers.”

New Insulation Offers High Thermal Efficiency, Minimal Thickness

Kingspan OPTIM-R Kingspan OPTIM-R is a next-generation insulation comprising rigid vacuum insulation panels (VIP) with a microporous core, which is evacuated, encased and sealed in a thin, gas-tight envelope to give outstanding R-values and an ultra-thin insulation solution. According to the manufacturer, the high level of thermal efficiency — up to R-28 on 1 inch and R-57 on 2 inch using calculated edge thermal resistance properties — combined with minimal thickness, provides an ideal solution for applications where a lack of construction space or depth is an issue, such as commercial roofing for single-ply low slope and IRMA systems.

OPTIM-R panels are accompanied with polyisocyanurate (PIR) insulation infill panels for single-ply systems or XPS insulation infill panels for IRMA systems, which can be cut to fit around problem areas such as sky lights or other roofing penetrations. In retrofit applications, OPTIM-R can provide solutions for areas that previously would have remained un–insulated because of insufficient space available. In new construction, the product can significantly enhance U–values/R–values in areas that would otherwise be accepted as diminishing the overall thermal performance.

Metal Roof and Walls Help Home Reach Lofty Design Goals

When Ilhan Eser and his wife Kamer decided to build their new home in Woodland, Calif., they had some ambitious criteria in mind. They wanted the home to not only be energy efficient, but to produce enough energy to be self-sustaining. They also desired a home with great aesthetics that fit in with the beautiful countryside and minimized impact on the environment.

Ilhan and Kamer Eser decided to design and build their own home on 80 acres of land in the California countryside. Their goal was to have a LEED-certifiable house powered by solar energy and protected by a highly insulated metal wall and roof system.

Ilhan and Kamer Eser decided to design and build their own home on 80 acres of land in the California countryside. Their goal was to have a LEED-certifiable house powered by solar energy and protected by a highly insulated metal wall and roof system.


As the CEO of Morin, a Kingspan Group company, Eser had another key design goal: to showcase his company’s metal roof and wall systems. “We wanted to do something that was good for the environment and the country,” Eser recalls. “So we said, let’s do a LEED-certifiable, net-zero house that will be a house of the future, if you will, using our company’s products. Our company is all about being environmental and being green and being sustainable, so that was the starting point.”

The result is a home that provides more than enough energy to meet its own needs with solar panels. It also captures graywater (gently used household wastewater) to use for irrigation and features a cutting-edge geothermal heating and cooling system that does not burn fossil fuels. All the household systems can be operated with a smartphone. “I believe in the future every house will be built like this, with your energy on top of your roof, basically,” Eser notes.

The metal roofing and wall systems are made of durable, highly recyclable materials and provide a high level of insulation to help keep energy costs down. The roof design features stunning angles, including an inverted “butterfly” roof over the great room to bring in the maximum amount of natural light.

As he began the project, Eser soon realized that he was breaking new ground in more ways than one. He found most residential architects and general contractors were unfamiliar with metal framing, roofs and walls, so he decided to tackle the design himself. He also served as his own general contractor, tapping into his 30 years of experience in commercial and industrial applications.

“I decided to look at it as if it were a light commercial building, and then I started finding people,” he says. “It was an interesting experience. I designed the house myself—although my wife had the overriding power, as always. She had to approve whatever I did, and when we had an argument, you probably can imagine who won.”

The Project Takes Wing

When it came time to discuss installing the roof and wall systems, Eser called Rua and Son Mechanical Inc., headquartered in Lincoln, Calif. According to President Louie Rua, the company focuses on metal roofing and wall panels—and that’s all they’ve done for the last 25 years. “We are very specialized in what we do,” Rua says. “We’re certified installers for most if not all of the metal roofing systems out there, and we also do our own custom fabrication. It’s become a niche market, so we travel around quite a bit.”

The roof of the Eser residence features unconventional angles, including a large section over the great room with an inverted butterfly design that required an internal gutter system.

The company has made a name for itself by excelling on high-end, intricate and cutting-edge metal projects that transcend typical warehouse applications. “We’ve found that when we go outside the box and take on the real difficult projects, the ones that are a little bit intimidating for other companies, that’s where we excel,” Rua says. “We’ve been doing it so long, and our team has a wealth of experience. When the trickier jobs come around, we are well equipped to handle them.”

This project was right up the company’s alley. “Ilhan was pretty adamant he wanted us to do it,” Rua recalls. “This was his personal house, so it was quite a compliment. I took on the challenge, and we took it very seriously. We worked through what it would cost, how long it would take, all the dynamics. His design team did all the preliminary design and then our team got in there and played with it a little bit and made a few tweaks. We put a lot of thought into those details.”

Rua admits the high-profile nature of the client and the complexity of the project were daunting. “Any job when you first jump into it and see it’s outside the box can be intimidating,” Rua says. “But then as you get familiar with it and start breaking it down and working through it, it gets easier. One of my lead superintendents, Fernando Huizar, was knee-deep in it, and he and Ilhan really hit it off, which is important. The relationship with our clients is our first priority, and on every job we strive to meet and exceed their expectations. It couldn’t have gone any smoother.”

Rua and Son Mechanical installed the double-layered roof and wall systems, which consisted of insulated metal panels (IMPs) and aluminum finish systems. The 7,500 square feet of exterior walls are made up of 4-inch-thick IMPs, topped with concealed-fastener panels. The mechanically seamed roof incorporates 8,000 square feet of 6-inch IMPs. The custom finish is Kameleon Dusty Rose, which changes color from green to yellow to silver to bronze to brown, depending on the amount of sunlight hit-ting it and angle from which it is viewed.

Symmetrical Metal Panels Create Watertight Seam

Morin, a Kingspan Group company, has introduced the SymmeTry Roof Series, a mechanically seamed structural roof system that is symmetrical and hydrostatic by design.

Morin, a Kingspan Group company, has introduced the SymmeTry Roof Series, a mechanically seamed structural roof system that is symmetrical and hydrostatic by design.

Morin, a Kingspan Group company, has introduced the SymmeTry Roof Series, a mechanically seamed structural roof system that is symmetrical and hydrostatic by design. A symmetrical metal roof system does not “lap” over an adjacent panel like standard asymmetrical panels. Symmetrical panels install side by side and have a mechanically seamed “cap” that has two beads of continuous butyl sealant, creating a watertight seam. MORIN’s SymmeTry Roof Series vertical panel legs range from 1 1/2 to 3 inches in height. Because they are bidirectional, the panels can be installed going left to right, right to left, and start from any point of the roof. Symmetrical panels are specified and installed to allow for unlimited thermal expansion and contraction, providing the advantage of installing panels up to 300 feet in length.
