Internally Lined Spiral Tubing

At Alpha Tube, we manufacture and supply internally lined spiral tubing that combines the aesthetic appeal of traditional spiral ducting with the added performance of built-in acoustic and thermal insulation. This makes it a popular choice for projects where both appearance and efficiency matter.

Key Features

• Pre-insulated with 6mm Pyrosorb Class O Foam – delivering excellent sound absorption and thermal control.

• Class O Fire Rating – improved fire safety compliance for modern HVAC systems.

• Operating Temperature Range: -30°C to +100°C – suitable for a wide range of environments.

• High-Density Insulation (>90kg/m³) – ensures superior acoustic performance.

• Antibacterial & Antifungal Properties – perfect for healthcare, retail, office, and high-spec residential systems.

Applications

Internally lined spiral tubing is designed for HVAC installations that demand noise reduction, thermal efficiency, and a professional finish. It’s widely used in:

• Commercial office spaces

• Healthcare facilities

• Retail outlets

• High-spec residential properties

Quality & Performance

Unlike external insulation, our built-in acoustic lining maintains the iconic spiral-wound appearance, while reducing the need for extra wrapping on-site. This not only improves installation speed but also keeps ductwork looking clean and professional.
