Alcoa Kawneer Business Introduces Its New InLighten® Light Shelf – a Versatile Solution That Enhances Energy Savings

New Design Maximizes Natural Lighting, Aesthetics and Value

NORCROSS, Ga.--Alcoa's Kawneer architectural aluminum business introduced its new InLighten® Light Shelf today. By using minimalist design principles, Kawneer has rewritten the energy saving value equation for its architectural light shelf. The design leverages minimal material content, sightlines, weight, installation and maintenance efforts, all while maximizing daylighting and design options at a competitive price. The ability to attach the minimal sightline light shelf to multiple Kawneer curtain wall systems and storefront framing systems makes it ideal for both new and retrofit projects.

Kawneer's new InLighten® Light Shelf has superior aesthetics, a tilt feature, enhanced performance and several fabrication and assembly advantages. At the core of functionality, architectural light shelves are designed to reflect sunlight deeper into the interior of a building by “bouncing” natural light up to the ceiling and have been proven to reduce perimeter lighting requirements and enhance the occupant experience. The new InLighten® Light Shelf features an extruded aluminum chassis system and offers several panel choices. In addition to the traditional opaque Reynobond® aluminum composite material (ACM) panels, lightweight translucent polycarbonate panels are now a standard offering. And, the availability of depths of up to 30-inches allows for the overall reflective surface to be maximized.

Versatility in Performance and Installation

InLighten® Light Shelf’s new design incorporates a unique mounting bracket that allows the panel to be effortlessly tilted for care and cleaning. Additionally, panels can be fabricated and assembled in the shop, which significantly reduces time spent in the field before installation. InLighten® Light Shelf has been thoughtfully designed so it does not interfere with the installation or operation of typical window treatments and has been thoroughly tested using advanced finite element analysis (FEA) modeling techniques and physical testing.

Environmental Advantages

Architectural light shelves have become an integral part of the daylighting strategy for sustainable building design. Strategically placing the InLighten® Light Shelf can allow for maximum daylighting and reflect natural light deeper into occupied spaces. Light shelves have been proven to reduce requirements for artificial perimeter lighting, thereby conserving electrical energy costs. In addition to increased daylight control and energy savings, InLighten® Light Shelf can help earn Leadership in Energy and Environmental Design (LEED®*) credits in three categories: Materials & Resources – Recycled Content, Energy & Atmosphere – Optimize Energy Performance and Indoor Environmental Quality – Daylight and Views.
