3/4" x 36" x 1/2" Wall Fiberglass Insulation Cover

3/4" CTS Fiberglass Pipe Insulation – 1/2" Wall, 3' Length

This fiberglass pipe insulation is designed for use on 3/4 inch copper tubing and features a 1/2 inch nominal wall thickness. Measuring 3 feet in length, it provides dependable thermal protection and is commonly used in hot and cold water piping systems where energy conservation, condensation control, and mechanical durability are critical. The rigid fiberglass construction ensures consistent insulation performance across a variety of building applications.

Intended for professional use, this insulation meets commercial jobsite requirements for thermal efficiency and condensation prevention. The material is resistant to mold and mildew and is often jacketed or covered for additional protection in exposed installations.

Installation Overview

Before installation, verify that all piping is clean and free of surface debris. The insulation may be installed over pipe using appropriate adhesives or mechanical fasteners, depending on jobsite conditions and jacket type. Sealing joints and seams is critical for maintaining the vapor barrier and ensuring thermal performance. Protective jackets may be required for outdoor or high-traffic applications.

Applications for Contractors

This fiberglass pipe insulation is appropriate for use in commercial and residential mechanical rooms, service lines, and chilled water distribution. Its thermal resistance and structural rigidity make it a reliable component for meeting energy code requirements and managing system efficiency across new and retrofit projects.
