Description
Reviews (0)

BEEFLEX rock wool is made from dolomite and basalt melted at up to 1600 °C, spun into fine fibres by centrifugal force and pressed into boards, rolls and pipe sections.

The blanket is a long, flexible roll that is easy to unroll on site. It suits projects that need thermal and acoustic insulation and fire protection for floors, ceilings, roofs, boilers, tanks and hot pipes.
