Compared to uninsulated steel-framed box headers, Enviro-Beams TM provide dry insulation and vastly better thermal resistance..
ENERGY SAVING
Architects, Engineers, and Owners often assume that box headers are insulated. They often are not – due to the logisticts and scheduling of construction trades. Pre-insulated Enviro-Beam TM has a heat retaining value of R 22 for a 6-inch wall while a typical uninsulated box header has an R value of close to zero.
SUPERIOR STRENGTHBuilt from high quality galvanized steel channels, Enviro-Beam TM has superior strength to typical steel box headers. The insulation foam helps transfer wind load so the front and back channels work as a composite section, gaining strength and rigidity over the empty steel configuration of a traditional box header.
MOLD & MILDEW RESISTANT
The insulated double steel channel eliminates the possibility of weather-related water damage which may cause
warping or promote mildew or mold growth. Polystyrene foam insulation will not absorb water, discouraging growth of mold or mildew.
ENVIRONMENTALLY FRIENDLY
Made of recycled galvanized steel and recycled foam, Enviro-Beam TM meets LEED requirements for recycled material.
PRE-ENGINEERED
Since Enviro-Beam TM headers can be ordered to exact dimensions as seen in this website Engineering charts, or easily cut in the field, additional construction time and labor savings are realized.
