Section Two: Rockwool
Rockwool Mineral Wool Products
An advanced thermal insulation material made from natural mineral fibers derived from high-quality volcanic rock, melted and converted into thin fibers bonded together with a thermal binder, combining excellent thermal properties with high mechanical durability.
Thermal Properties
Very high thermal resistance with very low thermal conductivity, stable over the years without degradation.
Fire Resistance
Non-combustible, maintains stability even at temperatures exceeding 1000°C.
Acoustic Properties
Excellent sound insulation; the fibrous structure absorbs sound waves with high efficiency.
Moisture Resistance
Very low water absorption; its thermal properties are unaffected by moisture changes.
Chemical Properties
Unaffected by acids or alkalis, and completely resistant to bacteria, fungi and pests.
Long-Term Stability
Maintains its properties for more than 50 years without any degradation in performance.
Safety & Health
Very safe to use; the fibers are bio-soluble and are naturally expelled from the body.

Economic & Environmental Benefits
A Smart Investment for a Sustainable Future
40%+
Reduced Energy Consumption
Reduces electricity consumption for cooling in hot climates like the Gulf, with the investment paid back within a few years.
Space Savings
Very low thermal conductivity allows the use of thinner materials, freeing up additional interior space and reducing the weight of structural elements.
Fire Protection
The rockwool insulation layer slows the spread of fire and provides longer time for evacuation and rescue.
50+ Years
Long Service Life
Our products last for long periods without deterioration, meaning a long-term and cost-effective investment.
Improved Indoor Environment Quality
Good thermal insulation maintains a stable and comfortable indoor temperature, improving people's health and comfort.
Safety & Health
Rockwool is completely safe and reliable for human use; non-toxic and non-carcinogenic, and its fibers are bio-soluble and naturally expelled from the lungs.
Gloves when handling
Safety glasses
Masks in dry environments
Good ventilation during installation
Environmental Properties
Rockwool is completely environmentally friendly; it contains no ozone-depleting substances and is not classified as a hazardous air pollutant. In most ecosystems, the material is expected to break down over weeks to a few months.
