WINDOWS FOR ANY COMMERCIAL APPLICATION
EFCO offers one of the most complete aluminum window lines in the industry. Our products include projected, casement, top-hinge, pivot, hung, sliding and ribbon window systems for applications from new construction and window replacement to historical replication. Every window is custom designed, engineered and fabricated to your project's specifications. And systems are tested to meet AAMA performance standards and are classified as Commercial, Heavy-Commercial, and Architectural Window-Grade Products. Frame depths for EFCO windows range from 2" to 5-3/8". Our systems are available with internal, external or true muntins and can accept various glazing thicknesses. Our windows can also be specified with glazing options such as tints and between-glass venetian blinds. Screens, as well as special locks, rollers and other hardware, are additional customizing options.

SPECIAL-PURPOSE WINDOW DESIGNS
Rugged environmental conditions call for windows that provide special weather protection. EFCO offers options for conditions from extreme heat and cold to hurricanes. Most EFCO windows come in thermal versions designed to dramatically reduce heat transfer and provide significant energy savings. Our thermally broken models utilize either standard fill-and-debridge frame construction or Insulbar® two-piece frame construction, the latter of which allows the use of different interior and exterior window colors. Double or triple glazing is also available for additional heat-transfer protection. And Heat Mirror™ glass provides UV protection while maximizing energy savings by reflecting heat back to its source-to the outside in summer, the inside in winter. Many EFCO windows also come in models specially tested for hurricanes. These windows feature heavy-duty laminated glazing consisting of a special inner layer surrounded by two 3-1/16" glass panels. The glass helps the windows resist penetration from flying debris while providing the same visibility as standard glazing. EFCO hurricane systems are certified to meet the strict new building standards of Florida's Dade and Broward counties.

PERFORMANCE YOU CAN COUNT ON
EFCO systems are factory tested to deliver long-lasting performance against the elements. Windows receive tests for both water and air infiltration, and thermal windows receive an additional test for thermal transmittance. The quality of every EFCO window is backed by a limited warranty. And optional extended warranties are available to meet specific project requirements.

QUICK-TURN DELIVERY
When short lead time is a primary project concern, our EFCO Express™ program can deliver the systems you need in just 15 working days or less. A variety of windows, as well as storefronts and several models of doors, will be custom built and finished in your choice of our standard paint colors, or anodized finishes.
