Fiberglass Blanket


RW-4300 / RW-4600 are white mineral fiberglass insulation blankets in 61 cm widths in 1.22 m and 2.44 m lengths. Manufactured from silica sand lubricated with mineral oil to protect against abrasion; developed to withstand temperatures up to 538°C (1000 °F).

It is ideal for the insulation of piping for industrial use, such as oil refining, power generation, chemical, petrochemical and shipping industries. Thanks to its different types of reinforcement, it adapts to irregular surfaces of equipment and process piping.

  • Excellent thermal efficiency
  • Easy to install and handle
  • Does not promote corrosion
  • Non-combustible
  • Low maintenance and long life
