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

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

This 36-inch fiberglass pipe insulation section is designed for use on piping with a nominal 1-inch iron pipe size (IPS). Featuring a 1/2-inch thick wall, it provides consistent thermal resistance for commercial and residential mechanical systems. Commonly applied in hot and cold water lines, HVAC piping, and process systems, this rigid molded insulation is suited for both new installations and retrofit applications.

The insulation is manufactured to deliver effective control of heat loss, condensation prevention, and mechanical protection when jacketed. It complies with standard industry specifications for thermal performance and is appropriate for aboveground piping systems in indoor or protected environments.

Key Product Features

• Fiberglass Core – Offers stable thermal performance and dimensional integrity under temperature fluctuations.
• Standard 1/2" Wall Thickness – Helps meet energy code requirements for mechanical insulation applications.
• 36" Length – Reduces installation time by covering longer pipe runs with fewer joints.
• Field Modifiable – Can be cut to fit fittings, elbows, and pipe lengths using basic tools.
• Low Thermal Conductivity – Provides consistent R-value across a broad range of operating conditions.

Installation Guidelines

Prior to installation, ensure the pipe surface is clean and dry. The insulation may be applied using mechanical fasteners or suitable adhesives, depending on jobsite requirements and jacket selection. All seams and joints should be sealed to maintain thermal integrity. In exposed installations or where impact protection is needed, apply an appropriate all-service jacket (ASJ) or vapor retarder covering.

Application Considerations for Contractors

This product is used in commercial and residential piping systems to improve energy efficiency and meet mechanical code compliance. It performs reliably in chilled water, hot water, and general utility service. Its rigidity ensures compatibility with support spacing and pipe hangers in accordance with standard insulation specifications.
