MINERAL FIBER INSULATION

TECHNICAL DATA

General Product Information:

Auralex® Mineral Fiber Insulation is made from basalt rock
and slag. This combination results in a non-combustible
product with a melting point of approximately 2150°F
(1177°C), which gives it excellent fire resistance properties.
