Sectional: Insulated The Best Commercial Garage Door

The Insulated Sectional door is Garage Headquarters' top-of-the-line, high R-value door, designed exclusively for the commercial and industrial sectional overhead door market. It is constructed using foamed-in-place polyurethane insulation, which creates a strong, energy-efficient monolithic panel.

Each Insulated Sectional door is secured with standard 14-gauge, galvanized steel hinges. The interior skin of each section has two continuous, horizontal, 20-gauge reinforcing strips. The section joint is thermally broken and chemically bonded with a pressure-sensitive adhesive sealant. An EPDM rubber weather seal further enhances the performance of the joint.

Garage door service specialists are standing by to answer any questions about your Boston and Providence overhead doors. Call us today to find out if the Insulated Sectional door is right for your business.
