New Modular Wall Panel Series Offered by ATAS

ATAS International has added another profile to their concealed fastener wall panel offering.  The Design Wall™ Reveal is a modular wall panel series designed as a drained and back ventilated (D/BV) assembly.

This puts an air gap and drainage plane  between the panel system and structural wall, allowing wind-driven rain or moisture to escape the building envelope without entering the building.

 D/BV systems are also designed to remove moisture that penetrates it through vapor drive from within the building or from the outside environment.

The panels are offered in various widths, depths, and lengths to create a unique appearance. It may be installed horizontally or vertically without the need for any sealants, gaskets, or splines to create the dry joint.  Panels are installed from the top of the wall down, and from left to right.  

Design Wall Reveal is a great light-gauge alternative to other heavier plate and Metal Composite Material (MCM) panels.  This new modular panel can be perforated, for use as equipment screens, sunshades, or for other building aesthetics.

INSPIRE HP Opens up a New World of Opportunities!

Because of such high, breakthrough performance, the InSpire HP from ATAS International opens a full range of new possibilities for solar air, such as:

  • Direct heating of open-space buildings
  • Water-preheating in the summer
  • Coupling with heat pumps for heating in the harshest winter conditions
  • Regeneration of desiccant wheel systems
  • And much more

Knowledge Gain

  • Maximum heating temperature of the InSpire HP is as high as 90°F above ambient.
    • No other competing solar heater known has achieved better than 60°F above ambient.
  • Solar heating output results showed 25% to 30% increase over previously tested solar air heating collectors.
    • Solar yield has shown to be 35% greater as compared to other tested transpired solar collectors.

New ATAS Online Education Course

ATAS International has a new education course on Hanley Wood University. “Using Technologically Advanced Metal Building Products in LEED, Net Zero, and Passive Buildings” is approved by the AIA (for one LU/HSW) and GBCI (for one continuing education hour). 

This course appears in the June issue of Architect magazine and on the Hanley Wood University website. The learning objectives for this course include:

  • Understand the basic design principles behind LEED, Net Zero, and Passive House buildings.
  • Examine how technologically advanced metal siding and roofing products can be used in sustainable building design.
  • Discover how these innovative metal building technologies can help projects meet LEED, Net Zero, and Passive House standards.
  • Explore case studies where metal building products were used to meet green building standards in both commercial and residential projects.

Four case studies are incorporated into the course. A university building in Illinois pursuing LEED Gold certification and a middle school in Pennsylvania which already achieved LEED Gold are included. Another university building in Pennsylvania which achieved Zero Energy certification is featured, and solar-ready metal roofing helped them achieve that goal.  As well, readers will learn about a multifamily residence in New York that earned both Passive House and Net-Zero Ready certifications.

Lee Ann Slattery, LEED AP BD+C, said, “Metal building components can assist in achieving many different green building certifications.  From insulated metal roof and wall panels, to transpired solar collectors, to above sheathing ventilation, to energy efficient paint coatings and solar-ready metal roofing, they all contribute toward creating a sustainable building and a better environment for its occupants.”

Cool Roofing

ATAS is redefining cool with its cool metal roofing products and capabilities. Many options are available to create roofs for residential and commercial construction with customized cool components.

Cool pigment paint reflects infrared radiation, allowing the color to appear the same while keeping the material cooler. This helps in reducing the urban heat island effect, and many of our colors qualify for LEED® Heat Island Credits. The 70% PVDF finishes that are used carry a 30-year limited warranty addressing fading and chalking.

ATAS coated materials are non-staining and virtually maintenance free. Any surface residue is easily removed with conventional cleaning solutions or detergents. The coatings are so cool that they meet national energy standards and guidelines. Many ATAS roofing products comply with the stringent California Title 24 Energy Efficiency Standards. LEED® credits also can be acquired because the ATAS coatings meet the minimum required solar reflectance index value set by the U.S. Green Building Council. An added bonus is that metal roofs can contribute LEED® points beyond what the coating contributes; for instance, adding points with solar systems.

Additionally, our new patented Above Sheathing Ventilation Spacer Shim creates energy savings by reducing air-conditioning costs in the summer, providing ventilation spaces in increments of 3/8″.
