Tubelite offers Therml-Block door products with thermal barriers that are manufactured using EcoLuminum, a high-recycled-content aluminum billet composition. The door and frame use an I-shaped thermal strut reinforced with 25% nylon fiber. Doors are available with a 4" medium stile and 5" wide stile. The thermally broken construction allows for different finishes on the interior and exterior surfaces to match color schemes. •
