AFS-Tubelite_INT14_crosscut_web.jpgBlending transparency and flexibility within commercial spaces, the new Tubelite INT14 Interior Flush Glaze Framing system offers versatile design options for floor-to-ceiling room enclosures or free-standing partitions. Expanding choices for facility managers, design professionals and glazing contractors, the INT14 system provides necessary separation and prioritizes daylight, visual connection and sound reduction.

Paired with Tubelite side-hinged entrance doors, the INT14 interior framing system delivers a comprehensive solution for fast-track construction and renovation projects in open plan offices, schools, retailers and other interior build-outs. The Tubelite INT14 system is engineered to interface easily with typical metal stud and drywall construction. Its aluminum frames can be installed either before the drywall, after the drywall to completely cover the end of the stud wall, or as a free-standing system.

The Tubelite INT14 system has a standard 2-inch face and 4.5-inch depth for trim sightlines and optimal viewing areas. This flush-glazed system accommodates most configurations, 90-degree, 180-degree and “T” post mullion/corner options. Rotational mullions allow angular wall corners greater than 90-degrees. Butt-glazed details in both standard storefront and channel-style head and sill options also are available.

AFS-Tubelite_INT14_render_web.jpgINT14 is designed with 0.5-inch glazing as standard and there is no need for adaptors to manage different glass thicknesses. High-performance acoustic glazing in standard 0.5-inch laminated glass thickness has been tested to achieve a Sound Transmission Class (STC) of 34 and an Outdoor Indoor Transmission Class (OITC) of 32.

Along with supporting occupants’ acoustic comfort and well-being, Tubelite interior framing systems assist facilities with sustainability goals. Tubelite offers EcoLuminum® extrusions for its framing and entrance systems manufactured with recycled aluminum content and environmentally responsible finishing. Enhancing interior design and décor, Tubelite’s framing and door systems can be finished in a full selection of standard architectural paint and anodize colors. Specialty and custom finishes also can be selected, such as metallics, micas, textured wood grain and terra cotta.

The new Tubelite INT14 Interior Flush Glaze Framing system builds on the success of its INT45 and INT67 Interior Framing systems. To learn more about Tubelite architectural aluminum products, please visit
