Occupational Health and Safety
Glasswool and rockwool insulation products are excellent insulation materials and are fully safe to use under all conditions. Both insulation materials have been in world-wide use for over 70 years, and during this time their manufacture and use have been extensively monitored and researched.
It is clear from this monitoring and research that no serious health effects have ever occurred in those manufacturing, using or otherwise exposed to glasswool or rockwool insulation.
