The Metal Construction Association (MCA), expanding the use of metal in construction through marketing, technology, and education, has recently taken steps to make architects, architectural students, universities, and builders more aware of benefits of insulated metal panels (IMP), a type of paneling that will be known for its efficiency, high performance, reduced erection time and coordination, thermal performance, and aesthetics.
First, insulated metal panels are installed outboard of a metal stud cavity or other support system, minimizing thermal short circuits. Secondly, the panels incorporate a metal air and vapor barrier, eliminating other materials and construction trade coordination. Third, insulated metal panels provide highly efficient insulation in a small space. Fourth, the panels also provide a metal aesthetic exterior in a variety of sizes shapes, and colors. Superior thermal performance of insulated metal panels shadows standard wall construction practices and how they meet current and pending thermal code guidelines.

“Architects and contractors need to know, not only about the IMP, but also about the limitations of current wall construction methods, new thermal codes requirements, and how to build a quality exterior metal wall system,” said Scott Kriner, MCA spokesperson.

Recognition by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) of the shortcomings of insulated metal stud cavities, along with increased thermal performance requirements, has illuminated IMP as a uniquely efficient solution.

“Insulated metal panels have been manufactured for over 30 years, yet unlike other construction materials, knowledge of the benefits and uses of this product are limited in the architectural community,” remarked Kriner. “Now, with new energy codes and moisture control concerns, insulated metal panels provide a unique high performance solution in a compact product, eliminating other materials and reducing field labor.”

Insulated metal panels were one of the first exterior wall systems to install insulation outside of the support system without compromising thermal performance. Now, other systems are attempting to find similar answers, but must contend with various trades, insulation material efficiency, thermal short circuits and fire code acceptance. Currently, IMP systems are one of the few that meet all the performance criteria with minimal compromising.

“It is a product with a rich history, but made to meet and exceed the requirements of the future,” finished Kriner.

The metal roofing industry has had a “love/hate” relationship with snow retention systems. While the inability to control the release of snow may be the only major weakness of metal roofing, the industry has not embraced snow retention systems. SNOWGRIP, a new “first of its kind” snow retention coating, may be the system the metal roofing industry has been waiting for!

www.snowgripit.com has been designed to create SNOWGRIP believers in ten minutes or less. The 8-minute video on the home page and 30-second video on the 4th page provide an efficient orientation to SNOWGRIP with powerful imagery and an easily understood presentation. The site has applications for contractors, specs for architects and an online “Request for Price Quotation” form.

In addition to impressive snow retention capability, SNOWGRIP benefits include easy installation, affordability, enhanced roof performance/energy savings and more. SNOWGRIP has patents pending in the US and Canada and is available immediately to install before next winter’s snow falls.

SNOWGRIP is a “must see” product!

SNOWGRIP is a two-part Monolithic Abrasive Snow Retention Coating for metal roofs located in snow country. SNOWGRIP is so effective and so simple to install, it will enable Metal Roofing Manufactures to address their snow retention problem, while gaining market share against asphalt and membrane roofing. SNOWGRIP is designed to coat the entire roof to prevent any portion of the snow pack from beginning to slide.

SNOWGRIP promotes a uniform lightweight dehydrated insulating snow layer that remains on the roof. The base coat is a top quality liquid rubber membrane roof coat that bonds to the metal roof surface and secures the topping application of special abrasive granules that protrude from the SNOWGRIP surface. Snow and ice conforms to SNOWGRIP’S abrasive textured surface, creating a bond like none other in the roofing industry. The gravitational forces quickly bring the melt water into contact with SNOWGRIP roof surface. The traveling water efficiently flows off the roof system through natural airspaces, which formed below the insulating snow layer and between the raise SNOWGRIP granules.

The insurance industry doesn’t offer coverage for those who are injured or killed by ice and snow falling off roofs, calling such occurrences an “Act of GOD”. These insurance practices place an extreme liability on building owners and others. The SNOWGRIP “hybrid” metal roof solution will save millions spent on litigation, property damage and maintenance costs associated with snow slide accidents and ice dam claims. “SNOWGRIP is most likely a field applied application, but it may be possible to develop a pre-erection or factory applied finish.” A SNOWGRIP spokesman stated “The product is an ideal new profit center for a metal building contractor network and will create opportunities for theses contractors to provide additional service to past customers.”

SNOWGRIP is in the process of applying for an Energy Star Partnership. SNOWGRIP has several colors that are extremely reflective, reducing solar heat during the summer months. SNOWGRIP will also save energy in the winter, maintaining a dehydrated lightweight insulating snow layer on roof’s surface.

SNOWGRIP inventor Wes Fontecchio has spent years coating old metal roofs and repairing the damage caused by sliding ice and snow. A team including an architect and construction professionals formed to develop and market SNOWGRIP.

CAMBRIDGE, MD… Long and narrow vertical mesh panels from Cambridge Architectural
add a sophisticated, clean design and a durable exterior cladding to the newly-expanded
municipal parking garage at the Minnesota BioBusiness Center in downtown Rochester, MN.
Located in the heart of the city, among some of the country’s most prominent research and
development institutions like Mayo Clinic and IBM Rochester, the 8-story Minnesota
BioBusiness Center was developed by Rochester’s Economic Development Authority to provide
a prime operating location for biotechnology and medical device companies. The connected
parking garage serves the institutions and the public, and helps add to the aesthetic allure of the
notable restaurants, shops and businesses that surround it.

A Cambridge Parkade™ architectural mesh system veils the east and west facing facades of the
garage, sleekly dressing up the concrete structure. On the east-facing side, the mesh also
complements the glass exterior of the pedestrian walkway system connecting two of the
Minnesota BioBusiness Center’s main buildings, blending in perfectly with their architectural
style. At night, Cambridge’s mesh elegantly diffuses the light emitted from inside the parking
garage, creating a glow that softens the structure’s look.

“The new parkade is located right on Rochester’s ‘main street,’ among pedestrian-related
businesses and other attractions,” says Terry Spaeth, Senior Administrative Analyst for the City
of Rochester, which owns the facility. “Cambridge’s material helped to create the perfect
aesthetic for such a highly-visible building, and it’s been a great addition to the city.”
Construction and operation of the Minnesota BioBusiness Center parkade, like all new buildings,
needed to be cost-effective and efficient. Cambridge’s architectural mesh was chosen for the
building’s façade because it managed to adequately cover the structure’s exterior without
restricting airflow – always an important consideration for parking garages. Additionally,
Cambridge’s metal fabric is well known for its ability to withstand extreme temperatures and
harsh winters like those in Minnesota.

“Our experience, not only with parking garages, but also with harsh climates, made this project a
natural fit for us,” says Heather Collins, Director of Marketing for Cambridge Architectural.
“We’ve always been able to deliver an elegant-looking material backed up by surprising strength,
and the Minnesota BioBusiness Center is the latest example of that.”

Cambridge is committed to assisting the design and construction team from initial concept to
final installation on each and every project. For the Minnesota BioBusiness Center parkade,
Cambridge developed an ideal system to address all the visual and functional needs of the
exterior cladding. The system was then specifically engineered to fit the structure’s openings,
making installation as simple as possible.

The Parkade system was fabricated with mesh in Cambridge’s Mid-Balance pattern, which
features large-scaled, flexible open weaves that shade and screen structures including facades,
parking garages and pavilions.

Cambridge’s Scroll™ tension attachment hardware was used to install the Mid-Balance product.
Scroll is the only tension system to hide the attachment behind it, keeping the focus on the metal
fabric. It conceals the support by quarter-wrapping the bracket that attaches to the structural
support. The unique hardware grips the metal fabric and holds it in tension up to 100 feet.
Construction on the Minnesota BioBusiness Center parkade was completed in November 2009.
The project team consists of architect HGA, Rochester, MN, general contractor Adolfson &
Peterson Construction, Minneapolis, MN and owner, the City of Rochester.

Cambridge Architectural Parkade metal fabric solutions lend unique aesthetic appeal,
functionality, affordability and sustainable benefits to parking structures. As exterior cladding
for parking garages, Parkade applications provide ventilation, fall protection, visibility, headlight
attenuation, safety, security and many additional functional benefits. Cambridge offers a wide
range of metal fabric patterns and corresponding attachment hardware, and is always available
for comprehensive design and engineering assistance. With every project, Cambridge provides
turn-key installation.

March 3, 2011, Michigan City, IN – Architects, building owners and specifiers looking for ways to create more eco-friendly structures are turning to Kalzip roof and cladding systems. Whether the goal is to qualify a building for certification under the USGBC’s LEED standard or simply to use these guidelines to make a more energy and environmentally sound building, Kalzip can help accumulate points in at least three of the six categories in LEED New Construction, version 2.2. These include: Sustainable Sites, Energy and Atmosphere, and Materials and Resources.

Of the total 14 possible points in Sustainable Sites (SS), the use of Kalzip Nature Roof can reduce the impact of storm water and help accumulate a point in SS Credit 6.1: Storm water design; quantity control. Nature Roof is a vegetative or green roof that can retain water and reduce run-off to dramatically reduce drainage needs and water storage requirements at the site.

Kalzip standing seam roofing and Kalzip perforated facades can also help gain points in SS Credit 7.1: Heat Island Effect, Non-roof, and SS Credit 7.2: Heat Island Effect: Roof. For example, Kalzip standing seam roofing can be supplied with a painted surface that achieves the required Solar Reflectance Index (SRI) of 29, or in a natural stucco embossed finish, which has an SRI of 76 when new and 35 when weathered. If covered parking areas are used to reduce the heat island effect, Kalzip perforated facades can provide a wall covering that also offers natural ventilation.

In the Energy and Atmosphere (EA) Category, Kalzip offers more than one option to accumulate credits. Kalzip roofing and cladding systems can help improve thermal performance of the building envelope by achieving better U-values. Kalzip systems can achieve U-values as low as 0.016 Btu/h.ft2.F (0.09 W/m2K).

The use of vapor control layers and correct detailing at junctions, perimeter and penetrations can also help meet air tightness requirements as outlined in EA Credit 1 – Optimize Energy Performance. To earn points for EA Credit 2 – On-Site Renewable Energy, designers and specifiers can use a variety of Kalzip solar photovoltaic solutions. These include, Kalzip AluPlusSolar, an aluminum standing seam roof system with fully integrated solar PV cells; Kalzip SolarClad; a flexible PV laminate bonded to aluminum fabric that can be mounted on any of the Kalzip aluminum standing seam roofing systems; and PV panels clamped to Kalzip standing seam roofing. These framed PV modules can be mono-crystalline, poly-crystalline or amorphous silicone.

Kalzip’s recycled content and recyclability also help earn credits in the Materials and Resources (MR) category, which deals with construction waste and recycled content. Kalzip standing seam panels are predominantly made from aluminum alloy, which contains a mix of post-consumer and pre-consumer scrap as well as primary ingots, which can help earn credits for recycled content. Kalzip panels also can be recycled. Individual panels can easily be removed from an existing building with the Kalzip unzipping machine, which is designed to keep all panels in tact in the removal process. Additionally, the new Kalzip FC façade system allows single panels to be easily removed without compromising adjoining panels.

These are but a few of the examples of how Kalzip can be used to improve energy efficiency and environmental aspects of buildings. Kalzip technical experts are available to help identify other options for achieving these goals with Kalzip.
