Atco Rubber Products 010-R4.2_7X5FT Pipe Insulation Sleeve R4.2

Product Description

The ATCO RUBBER PRODUCTS 010-R4.2_7X5FT is a fiberglass pipe insulation sleeve designed to thermally insulate round ductwork and pipe in indoor HVAC applications. It provides an R-value of 4.2 using a thick fiberglass insulation blanket core wrapped in a reinforced metalized polyester vapor barrier jacket. Each section measures 7 inches in diameter by 5 feet in length and ships flat, ready to wrap. The pre-cut 5-foot sections reduce jobsite cutting time and material waste. Licensed HVAC technicians and insulation contractors install this sleeve on supply and return air duct runs, plenums, and round pipe in residential and light commercial systems.

This insulation sleeve is rated for indoor HVAC system use and performs across a temperature range of -20 degrees F to 250 degrees F, making it suitable for both supply air and hot-fluid pipe applications. The flat, blanket-style format wraps around 7-inch pipe or round duct without requiring custom fabrication. Pre-cut 5-foot lengths eliminate the need for in-shop or on-site cutting, which reduces labor compared to standard duct wrap roll applications. A starter cap is included. The reinforced vapor barrier jacket resists moisture migration and helps maintain long-term thermal performance.

Key Features

• R-4.2 fiberglass insulation blanket core for effective thermal resistance
• Reinforced metalized polyester vapor barrier jacket controls moisture migration
• Pre-cut 5-foot flat sections reduce jobsite and in-shop cutting labor
• Rated from -20 degrees F to 250 degrees F for broad indoor HVAC use
• Starter cap included for complete installation
• Meets UL 181B applicable standard

Compatibility

Designed for use on 7-inch round pipe and ductwork in indoor HVAC systems. Suitable for residential and light commercial supply and return duct insulation applications where UL 181B-listed materials are required.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors. Shut down the HVAC system and allow ductwork to reach ambient temperature before applying insulation. Secure all seams and edges with a UL 181B-listed foil tape or approved closure system per local mechanical code requirements. Do not compress the insulation blanket during installation, as compression reduces the effective R-value.
