1-1/2" x 36" x 1/2" Wall Fiberglass Insulation Cover, Copper Tube Size

1-1/2" x 36" Fiberglass Pipe Insulation – 1/2" Wall Thickness

This fiberglass pipe insulation section is designed for 1-1/2" nominal copper tubing and measures 36 inches in length with a 1/2" wall. Manufactured for thermal efficiency, it reduces energy loss and provides a barrier against temperature fluctuations in both hot and cold service lines. The rigid fiberglass core is encased in a durable vapor-retardant jacket, suitable for a range of mechanical and plumbing applications.

Engineered for use in commercial and industrial environments, this product offers consistent thermal performance and complies with typical mechanical insulation specifications. It is ideal for indoor piping systems requiring reliable temperature control and moisture resistance.

Key Features

• Fiberglass Insulation – Delivers consistent thermal protection for hot and chilled water lines.
• 1/2" Wall Thickness – Minimizes heat transfer and supports compliance with energy codes.
• Pre-Formed and Sized – Designed to fit standard 1-1/2" copper tube diameters without field modifications.
• 36" Length Per Section – Suitable for both straight runs and segmented applications.
• Durable Vapor Jacket – Helps maintain insulation integrity and resists surface moisture penetration.

Technical Specifications

• Material: Rigid fiberglass core
• Inner Diameter: For 1-1/2" nominal copper tube size
• Length: 36 inches
• Wall Thickness: 1/2 inch
• Jacket: Vapor-retardant facing (e.g., ASJ or FSK, depending on product variant)

Installation Guidance

Install over clean, dry piping using appropriate adhesive or tape at all seams and butt joints. Field-cutting is easily accomplished using a utility knife. Secure jacket overlap with matching closure tape. Ensure continuity of the vapor barrier for chilled water or refrigeration applications.

Professional Considerations

This insulation is compliant with mechanical insulation standards used in commercial construction, including ASTM C547 and applicable energy efficiency guidelines. It is suited for mechanical rooms, utility corridors, and other controlled indoor environments where pipe temperature maintenance is critical.
