Atco 010-R4.2_12X5FT Pipe Insulation Sleeve R-4.2 12 in X 5 Ft

Product Description

The ATCO RUBBER PRODUCTS 010-R4.2_12X5FT is a flat pipe insulation sleeve designed for use on 12-inch round pipe in indoor HVAC applications. The sleeve combines a thick fiberglass insulation blanket with a reinforced metalized polyester vapor barrier jacket to deliver an R-4.2 thermal rating. Pre-cut to 5-foot sections, the sleeve eliminates the need for in-shop or jobsite cutting, reducing both labor time and material waste. Each section ships with a starter cap included. Suitable for systems operating between -20 degrees F and 250 degrees F, this product meets UL 181B standards. HVAC technicians and insulation installers are the primary trades that handle this product.

This insulation sleeve is rated for indoor HVAC system use, specifically on 12-inch round pipe. The flat blanket format is easier to apply than conventional duct wrap, conforming to the pipe surface without the multi-overlap cutting typically required on larger diameters. The 5-foot section length makes handling and positioning straightforward in mechanical rooms, plenums, and equipment rooms where large-diameter pipe runs are common. The reinforced metalized polyester jacket acts as a vapor barrier, limiting condensation-related energy loss and protecting the fiberglass core.

Key Features

• R-4.2 thermal rating with thick fiberglass insulation blanket core
• Reinforced metalized polyester vapor barrier jacket for moisture control
• Pre-cut 5-foot sections eliminate jobsite and in-shop cutting
• Flat blanket format reduces labor time compared to duct wrap application
• Includes starter cap for complete installation
• Rated for temperatures from -20 degrees F to 250 degrees F
• Meets UL 181B applicable standard

Compatibility

Designed for use on 12-inch round pipe in indoor HVAC system installations where a flat pipe insulation sleeve with a vapor barrier jacket is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians or certified insulation contractors. Power down and isolate the associated HVAC system before beginning pipe insulation work on active duct or piping systems. Secure all seams and longitudinal joints per UL 181B closure requirements using listed tape or mastic. Avoid compressing the fiberglass core during installation, as compression reduces the effective R-value.
