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
