1/2" x 36" x 1/2" Wall Fiberglass Insulation Cover

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

This fiberglass pipe insulation section is designed for use on 1/2 inch copper tube size (CTS) piping and features a 1/2 inch nominal wall thickness. The 36-inch length provides effective thermal protection in mechanical systems where temperature regulation, energy conservation, and condensation control are required. Suitable for both residential and commercial installations, this rigid fiberglass insulation is commonly used on hot and cold water piping in compliance with energy and building codes.

Manufactured for long-term thermal performance, the insulation helps reduce heat transfer, maintains system efficiency, and supports pipe longevity by minimizing surface condensation. It is typically installed with a jacket or facing (not included) for mechanical protection and aesthetic finish in exposed applications.

Key Performance Features

• Rigid Fiberglass Core – Delivers consistent thermal resistance and structural stability in piping systems.
• 1/2" Nominal Wall – Standard thickness for energy code compliance in typical HVAC and plumbing projects.
• Condensation Control – Helps prevent moisture accumulation on cold piping surfaces, reducing corrosion risks.
• Precision Fit – Manufactured to fit 1/2" CTS piping, providing uniform coverage for efficient insulation.
• Cut-to-Length Capability – Easily trimmed in the field to fit pipe lengths and offsets as required.

Technical Specifications

• Pipe Size: 1/2 inch Copper Tube Size (CTS)
• Length: 36 inches
• Wall Thickness: 1/2 inch
• Material: Molded fiberglass insulation

Installation Overview

Install directly over clean, dry piping. Field joints should be sealed using appropriate adhesives or tape to maintain the thermal barrier. For exposed areas, an all-service jacket (ASJ) or vapor retarder may be required depending on the environment. This product is typically installed by mechanical contractors or insulation professionals but can be field-applied with basic tools when following industry practices.

Use Case Notes for Contractors

This insulation is widely used in hydronic systems, domestic water lines, and mechanical rooms. It provides reliable thermal protection while helping meet local and national energy conservation codes. Suitable for retrofit and new construction, it integrates easily into standard insulation assemblies and jacket systems.
