Business Overview

Double Wall Duct

Spiral Manufacturing provides high-pressure dual-wall insulated spiral pipe for HVAC systems that need thermal efficiency, noise reduction, condensation control, and durable airflow performance. The dual-wall design uses two concentric spiral pipes with factory-installed insulation between them, helping reduce job-site labor and protect the insulation from damage. Options include perforated acoustical liners for sound control and solid liners for thermal insulation. These systems support cleaner installation, lower maintenance needs, and long-term duct performance. Reach out to their team to review dual-wall spiral pipe options for your project.
