ROCKWOOL PLUS™ MB is a is a lightweight, non-combustible, semi-rigid mineral wool blanket insulation

ROCKWOOL PLUS™ MB is designed for pre-engineered metal building construction where an hourly fire rating is not required. Insulating buildings with ROCKWOOL PLUS™ MB will help increase energy efficiency, improve thermal stability and enhance fire protection for the overall comfort and safety of occupants.

Properties:

  • Lightweight, fire-resistant and sound absorbent
  • Strong—well suited for site durability
  • Easy to install, easy to cut
  • Water and moisture resistant—maintains R-value even when wet
  • Does not rot or promote the growth of mildew, fungi or bacteria
  • Sag-resistant for tight fits; high density ROCKWOOL PLUS™ MB never loses shape
  • Consistent thermal performances with high R-Values
  • ROCKWOOL PLUS™ MB can contribute to earning LEED® points
