MONETT, Mo. — May 14, 2012 — There’s a new curtain wall in town and it packs a powerful punch for thermal performance, structural integrity and design flexibility. EFCO representatives will showcase the new 8750XD unitized curtain wall, part of the XTherm family of products, in Pella and EFCO booth #2327 during the 2012 American Institute of Architects (AIA) National Convention and Design Expo, May 17-19, 2012, in Washington, D.C.

“We invite AIA expo visitors to check out the new XTherm 8750XD product from EFCO that delivers the structural elements needed for mid-to high-rise projects,” said Erik Sutton, manager of product marketing, EFCO. “Plus, this unitized curtain wall features superior thermal performance and design flexibility.”

Strength in numbers

The new aluminum curtain wall leverages Duracast® fiberglass composite technology in a patent-pending thermal break design. The new EFCO curtain wall is shop fabricated and assembled, which helps reduce field labor costs. With an industry-leading U-factor of 0.31 — a 35 percent improvement compared to conventional unitized walls — the 8750XD offers popular system profiles, multiple configuration options and integral vents for optimal design flexibility.

“With its superior thermal performance and structural integrity, thanks to its unique design that has a key element — Duracast fiberglass composite technology — glazing contractors, general contractors and architects will find the 8750XD an outstanding building envelope solution,” Sutton said.

EFCO XTherm line provides multiple options

Curtain walls

The EFCO 5600 curtain wall features an optional Duracast pressure plate that is 300 times better than aluminum for thermal conductance and provides a 27 percent gain in frame and glass U-factor. Because it features Duracast fiberglass composite technology in the pressure plate, the curtain wall’s thermal performance improves and it’s stronger than conventional fiberglass. Plus, the need for a gasket-type thermal isolator between the back member and pressure plate is eliminated - reducing installation steps to help save time and money.

EFCO’s 5500X curtain wall system offers an array of design and energy-saving options. This 2 1/2 " wide curtain wall system is capable of achieving U-factors as low as .19 for outstanding thermal performance. The curtain wall system offers a variety of accessories like snap-on face covers plus multiple color and finish options to meet a wide range of configurations and designs.

EFCO also offers interior light shelves — ideal for channeling natural daylight into interior space, reducing the need for artificial lighting and conserving energy. E-Lite™ and EZ-Lite fixed and operable interior light shelves are available in popular depths to meet design and energy-saving needs. EFCO E-Shade™ sunshades are an economical option to reduce solar heat gain and glare while allowing all-important natural daylight into a building. E-Shade is available in five standard lengths and designed to integrate with EFCO curtain wall systems.


Designed to meet energy-efficiency needs in commercial projects, XTherm 450X and 450G window series feature a deeper strutted thermal break for triple glazing while providing superior thermal separation of framing materials. For use in a variety of projects including educational to office to healthcare buildings, the windows offer exceptional U-value performance, dual glazing and optional integral blinds.

The XTherm HX45 double-hung window has a variety of outstanding energy-efficient commercial applications including schools, government buildings and green construction. The energy efficient design provides a substantial improvement in the interior frame temperatures. Both block and tackle and class 5 balances are available along with the quality auto locking and sweep lock hardware that has been a part of other EFCO products for many years.
