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.
- 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.
Aerocel White/Gray 25/50 Pipe Insulation in unslit tubular form can be slipped onto piping before it is connected, or it can be slit lengthwise and snapped over piping already connected. Butt joints and seams are to be sealed with contact adhesive; therefore, both surfaces to be joined are coated with adhesive. Aerocel White/Gray 25/50 is designed for installation above and below ground, indoor and outdoors. No protective finish is required.
In addition to the specifications listed below, Aerocel White/Gray 25/50 also conforms to the following: ASTM C 534, ASTM D 1056, NY City MEA #171-04-M, City of LA RR-8413, UL 181 Section 12 Mold Growth/Humidity, UL 181 Section 17 Air Erosion, UL 94 5 V-0, UL 723, NFPA 90A & 90B, MIL 15280J.
