Product Feature: Mineral Wool Insulation

Rockwool and Roxul Mineral Wool Insulation, other brands available

Mineral wool insulation is the best insulation option when it comes to insulating your floor (the ceiling of your crawlspace). Mineral wool insulation offers high R-Value options, with a product that is resistant to moisture. In addition to its moisture resiliency, if the mineral wool insulation comes into contact with moisture, it does not lose R-Value, which occurs with other insulation types.

Mineral wool insulation performs well on its own or can be incorporated with rigid foam board insulation installed in the rim joists and walls of your home. It can easily be cut to achieve an optimal fit around pipes, electrical wiring boxes, ductwork and between studs and joists that are less than standard width.

Comfortbatt® is a stone wool insulation product for use in wood and steel framing in both new residential and commercial builds and renovations.

This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceilings and floor frames.

Benefits of Using Mineral Wool in Comparison to Other Insulation Options:
  • Mineral wool is moisture resistant. If the insulation comes in contact with moisture, it does not lose retention value (or R-Value).
  • It does not promote growth of fungi or mildew due to its moisture resiliency.
  • Made from natural and recycled materials and contains no fiberglass.
  • Non-combustible and has excellent fire resistance up to 2150 degrees.
  • Provides excellent sound absorbency.
  • Better fit than fiberglass insulation—the material expands to fit within standard joist sizes.
  • Depending on your floor joist height, we offer R-23 to R-30 Mineral Wool insulation options for insulating your floor.
