Webinar: Understanding Stone Wool Insulation in Commercial Roofing

January 1, 1

This one-hour technical seminar will cover roof insulation board properties and the building science behind roof insulation strategies that improve thermal performance.

Research has shown how seasonal behaviour of foamed plastic insulation effects thermal performance and annual heat transfer.

This presentation will review how stone wool insulation strategies can play a significant role in the inevitable long term performance of the roof as it relates to year over year energy consumption, passive fire protection and measures for sound control.

Learning Objectives:

  • Identify the differences between stone wool and foam plastic Insulation.
  • Project applications for stone wool in roofing.
  • Define stone wool insulation and show how it’s made.
  • Discuss the features and benefits of using stone wool in a roof system.
