Luminous sky illusions

EcoSlim SkyCeilings are luminous sky illusions displayed in an ultra-thin, toxin-free, energy-efficient system. The low-profile design reportedly eliminates ceiling-clearance limitations, needing only 3 1/2 inches to install. The image tile is 1/4 inch below the illuminated edge-lit light guide, providing a bright image. The dimmable system provides 0% to 100% illumination control and is gasketed to prevent contamination of clean environments. Applications include healthcare, hospitality, commercial, institutional, and residential environments. The company uses evidence-based design research to support the product’s ability to alleviate stress and increase comfort and productivity.

Plan for Successful Door Installation

Building use, site location, and weather patterns affect the specifying and installation of commercial doors and windows.

The performance of a door or window is only as good as its installation. The installation, in turn, depends upon three things: the level of understanding and communication among the architect, contractor, and installer; the quality of the manufacturer's installation instructions; and the installer's expertise. Architects and contractors know that once the specification is written and the product selected, the need for planning and oversight has begun.

To foster uniform and reliable installation practices in the commercial sector, the American Architectural Manufacturers Association (AAMA), Schaumburg, IL, published Standard Practice for the Installation of Windows and Doors in Commercial Buildings (IPCB-08). This detailed methodology for the installation of exterior glass doors and windows in commercial buildings provides information for new construction and replacement projects. The publication addresses hinged and sliding commercial exterior doors incorporating large-glass vision.

Performance requirements

Designing for installed performance begins with meeting the application's requirements as set forth in standards and codes. In commercial buildings, live loads typically take precedence over dead loads (the weight of the stationary building components). Live loads are those that come and go or that change over time. Examples include wind loading, thermal expansion, seismic drift, and even the building's occupants. Live loads typically induce movement involving interaction among multiple building elements that extend beyond the glazed unit itself.

When specifying doors to withstand these and other conditions specific to the job site, remember that doors have distinct functional differences and application realities compared to windows. These differences stem from accessibility requirements, operating frequency, and water penetration.
