Wayne Dalton Garage Doors is excited to introduce a new all-window option for commercial sectional ThermoMark™ Model 5150. Perfect for both homeowners and commercial building owners, the all-window option is an ideal alternative for those seeking to achieve the sought-after look of an Aluminum Full-View garage door with the durability and reliability of our other insulated sectional steel doors. “Sleek, modern design has continued to grow in popularity for both homes and businesses. With the all-window door option, Wayne Dalton has been able to provide the desired aesthetic, while also maximizing light infiltration through the glass window panels,” said Wayne Dalton Brand Manager Sarah Schram. “The all-window door option is great for homeowners or facility managers seeking an eye-catching door.” The all-window door option is available in the Flush (Contemporary) panel in both short (Clear I) and long (Clear III) windows. ThermoMark Model 5150 is made with foamed-in-place polyurethane insulation sandwiched between the steel sections of the door for enhanced thermal performance. For residential applications, the all-window option should be ordered as a ThermoMark 5150 door. For residential examples, please see Wayne Dalton’s Classic Steel Model 8300.
