New Environmental Product Declaration for IMPs

By: Jane Martinsons, Metal Construction Association

An Environmental Product Declaration (EPD) for insulated metal panels (IMPs) is now available from MCA.

EPDs provide life-cycle assessment information and details about the product’s environmental impact (i.e., raw-material extraction, transportation, packaging, and disposal).  As such, EPDs assist purchasers and users in making informed comparisons among products.

“With the recent approval of LEED v4 rating system, we expect to see more members of the design community looking for EPDs as part of an overall emphasis on transparency,” notes MCA Technical Director Scott Kriner.  “The EPD for IMPs is based on the life-cycle assessment of this product category. It is a major step forward for the metal construction industry in reporting the environmental impact of IMPs.”

IMPs are composed  of rigid foam that is sandwiched between two sheets of coated metal. Their steel or aluminum panel facings create a vapor, air, and moisture barrier that provide long-term thermal stability. According to MCA-member manufacturers, IMPs

  • offer long-term durability
  • come in a multitude of colors and finishes
  • offer cost-competitive construction advantages and long-term high performance to help lower operating costs for building owners in any construction market.

Grand Central Terminal Turns 100 – Thanks in Part to Copper Roof

By John Ryan, Metal Construction Association

 Grand Central Terminal This month Grand Central Terminal in New York City is celebrating its 100th birthday. The iconic landmark has been a transportation hub for generations of travelers and commuters, and a destination for tourists and visitors looking to get a flavor for the Big Apple’s history.

I had the good fortune of working several blocks of Grand Central for several years prior to joining the Metal Construction Association, and often visited it to grab a bite for lunch, meet a friend who was coming to town, or just to enjoy the beauty of the main concourse.Grand Central Roof Detail 2

While the main concourse is stunning, and on each visit I would notice for the first time architectural details that I had never noticed before, I always found Grand Central’s copper roof to be striking. With its green-patina and ornate details, it seemed to be the perfect crown for one of the city’s most impressive landmarks.

But after spending time with MCA, I now have a greater appreciation for what that roof represents. It’s not just a beautiful architectural detail, but it’s also a high-performance feature that helped the building stand the test of time. The original roof, installed in 1913, was recently replaced with a new copper roof as part of a recent renovation, even though engineers determined that it was still serviceable almost 100 years later. That’s something that the average person might take for granted, or not fully appreciate. But not only did the copper roof look great, it performed well for nearly a century.Grand Central - Roof Detail

That’s 100 years. In New York City. That is quite an accomplishment, and speaks to the performance and beauty of metal roofs.

Explore Metal Roofing’s Many Green Benefits

Sykes Chapel uses metal for roofAlthough metal roofing is now considered a building product of choice among a vast legion of green-minded customers, sometimes we need to be reminded of its many ecological benefits. A recent Metal Construction Association technical bulletin provides a quick but very thorough rundown of metal roofing benefits, including that metal roofing:

• Can virtually eliminate the need to use future raw materials to produce roofing.
• Is unaffected by hot-cold or wet-dry weather cycles that break down other materials.
• Has recycled content ranging from 25% to 95%.
• Is fully recyclable if it is removed, perhaps as part of a building renovation.
• Is low weight compared to other roofing materials, which helps extend the life of buildings, among other benefits.
• Does not pose a health risk.
• Is increasingly regarded for its energy efficiency.

Building Green Gathers Momentum

GreenBuild Expo Logo

Representatives from the Metal Construction Association’sThe Metal Initiative, attended the Greenbuild Expo in San Francisco last week. It was great to be in a setting where so many professionals are devoted to building green. The movement has shifted, however—architects and building owners are building green not just because they want to do the right thing, they are doing it because it makes good business sense.

According to a new study released at Greenbuild 2012 by McGraw-Hill Construction, the top reasons for building green are client demand, market demand, lower operating costs and branding advantage. In 2008, the top reasons were doing the right thing and market transformation. This shift signifies that firms are seeing the value in building green, and that it can strengthen their bottom line. And building green is not just for new construction; renovation projects also reap the benefits, including near-term and long-term operating cost savings for building owners, as well as increased building values. (You can read the full article with additional details about McGraw-Hill Construction’s new study on the United States Green Building Council site.)

It was great to see so many MCA member companies exhibiting at Greenbuild 2012, and a reminder of the many green benefits in building with metal. Metal construction products have high recycled content and are recyclable, have fully developed distribution networks and are energy efficient. Their many benefits allow them to qualify for points in the United States Green Building Council’s LEED program. And their design flexibility allows architects and building owners to achieve design goals while building green.

Metal Roofing – A Perfect Option in Cold Weather

By: Brian Partyka, Drexel Metals

Cold enough?  The last thing you should be doing during a winter snow storm is having to worry about roof leaks caused by ice dams!

That’s why a metal roof is a perfect option for you!

Nationwide, roofing contractors receive hundreds of calls a month from owners looking for solutions to end problems during the winter freeze and thaw cycles that can abuse certain roof systems.

Ice dams form during these cycles and create a tremendous amount of weight, lift shingles and cause roof leaks. Ice dams are mainly caused by heat loss that escapes out of the owners building at the eaves of the roof. These ice dams are adding to energy costs and shortening the lifecycle of the roof system. The solution requires adding additional insulation at the eaves and installing a metal roof.

No Ice dam for you!

Residential and commercial metal roofing has continued to gain market share for a number of reasons, they are energy efficient, they qualify for a tax credit and most importantly their ability to resist weather ailments such snow, acid rain and hurricanes.
