Contributing to environmental and energy-efficiency goals, Tubelite Inc. offers Therml=Block™ door products with thermal barriers. These insulated doors and frames are manufactured for quick installation and, once installed, reduce the transfer of hot and cold temperatures, mitigate interior frost build-up and require minimal maintenance for long-lasting, smooth operation.

Mary Olivier, Tubelite’s marketing manager explains, “The door and frame utilize an I-shaped thermal strut reinforced with 25% nylon fiber. When matched with high-performance glass, Tubelite’s Therml=Block entrance systems dramatically improve performance in all categories, including U-factor and CRF. In addition, each assembled extrusion must pass a shear test of 1,000-pound minimum.”

The doors are available in both 4-inch Medium Stile and 5-inch Wide Stile. There also are options for a 4-inch, mid-rail and rabbet stiles for continuous hinge application. The meeting stile on a pair of doors includes Tubelite’s improved, adjustable astragal and standard weathering. The aluminum, thermal door frame’s exterior face displays a 2-inch sightline and 4.5-inch depth.

The aluminum for Therml=Block door products can be extruded by Tubelite using EcoLuminum™, a high recycled-content aluminum billet composition with eco-friendly, durable finishes. The door and frames’ construction allows for different finishes to match both exterior and interior color schemes. Tubelite’s painted finishes are applied and controlled in an environmentally effective manner.

Tubelite’s Therml=Block door products join the company’s other energy-saving products, which include the Therml=Block 300ES Curtainwall. These curtainwall and entrance systems can be paired with Tubelite’s daylight control systems, such as Max/Block™ sun shades and aLuminate™ light shelves. With the combined benefits of thermal performance, daylighting and recycled content, these products may assist projects pursuing certification through the U.S. Green Building Council’s LEED® Rating Systems.
