Stone Wool Insulation in Commercial Roofing for Thermal, Fire & Sound Control

GBCI: 0910000229

Provides an overview of the physical and performance properties of stone wool insulation and its production process. It includes examples of various commercial roofing applications and identifies the key benefits of using this insulating material versus some of the other insulating materials traditionally used in the North American market.
Eligible for 1.0 CE HOUR.
  • 1.0 CE

LEED version: v4, v2009



Energy codes and green building require us to design higher levels of performance in buildings, and today, architects have an increasing number of choices when it comes to specifying building insulation. The criteria for selecting an insulation for a specific application goes beyond long-term thermal performance and includes moisture protection, fire resistance, sound control, dimensional stability, and overall cost. Climate driven R-value (CDRV) is a newly developed concept in which insulation is recognized to perform differently across different temperatures and climate zones. When more accurate R-values are used in energy models, you can provide the building owner with more accurate energy calculations, thereby adding credibility and reducing liability.
This presentation reviews the unique and valuable properties of stone wool insulation that enable it to maintain consistent R-values over its lifetime. Unlike foam plastics, this natural stone material has inherent functional characteristics that make it highly durable, sustainable, stable, and impact, moisture and fire resistant. In addition to reviewing the benefits of stone wool insulation, discussions examine the different ways that stone wool insulation addresses energy and moisture management on flat or tapered commercial roofing systems.


  1. Discuss the origin and properties of stone wool and how it is manufactured into stone wool insulation products.
  2. Identify the key differences between stone wool, glass fiber, and foam insulations.
  3. Discuss the key benefits of stone wool that improve building performance over and above a discussion about R-value.
  4. Recognize the sustainable aspects of stone wool and how its installation may contribute to the accumulation of LEED® credits.
  5. Identify applications for stone wool in commercial buildings.
