Rockwool blanket 50mm is stone wool insulation for pipes, ducts, ovens and walls.
It also helps with fire stopping and sound control.
What is a rockwool blanket 50mm?
Mineral and ceramic fibre insulation comes as flexible blankets, rolls and rigid boards. Ceramic fibre handles the highest temperatures, so it lines furnaces, kilns and boiler doors. Rockwool (stone wool) suits hot pipes, ovens, fire protection and sound control. Fibreglass is light and common for ducts, roofs and moderate temperature equipment.
Thickness and density set the insulating value. Therefore, thicker blankets are used on hotter surfaces or where heat loss must be lower.
