Aerocel® White/Gray


Closed Cell Elastomeric Thermal lnsulation for HVAC & Refrigeration

Aerocel White/Gray 25/50 Tubular lnsulation is a flexible, closed cell and light weight EPDM* based elastomeric material designed for insulating liquid cooling and heating lines. 1/2″, 3/4″ and 1″, 1-1/2″ and 2″ wall, in popular I.D. sizes up to 6-5/8″. The closed-cell structure of Aerocel Pipe lnsulation makes it an efficient insulation.

Aerocel White/Gray 25/50 is manufactured to consistently provide actual values on these key performance criteria for mechanical system insulation:

Thermal Conductivity: 0.25
Water Vapor transmission: 0.1
Fire Rating: Will not contribute significantly to fire (simulated end-use testing).

Aerocel WhitelGray 25/50 Pipe Insulation, in 1/2″, 3/4″ and 1″ thicknesses has a flame spread rating of 25 or less and a smoke developed rating of 50 or less as tested by ASTM E 84 “Surface Burning Characteristics of Building Materials.”

Note: Numerical flammability ratings alone may not define the performance under actual fire conditions. They are provided only for use in the selection of products to meet limits specified.

Key Features

  • Low thermal conductivity
  • Easy to install
  • 25/50 rated through 2″ wall
  • Versatile, for heating, AC, refrigeration, plumbing


Aerocel White/Gray 25/50 Pipe lnsulation is used to retard heat gain and control condensation drip from cold-water plumbing, chilled water, and refrigeration lines. It also efficiently reduces heat flow for hot water plumbing and liquid heating and dual temperature piping. The recommended temperature usage range for Aerocel Pipe lnsulation is -70°F to +257°F .

Resistance to Moisture Vapor Flow

The closed-cell structure of Aerocel White/Gray 25/50 lnsulation effectively retards the flow of moisture vapor, and Aerocel White/Gray 25/50 is considered a low transmittance vapor retarder. Aerocel White/Gray 25/50 requires no supplemental vapor-retarder protection.
