Mineral Wool Insulation Pros and Cons - Solar365

What is it?

Mineral wool is a fiber insulation like fiberglass, but it is made of natural materials instead of glass. There are two types of mineral wool: rock wool consists of fibers of natural stone (basalt or diabase, for example); slag wool consists of fibers made from iron-ore waste. It is sold in batts and as loose-fill, just like fiberglass. Mineral wool was, for many years, the most widely used type of insulation in North America and Europe.

Advantages

• Mineral wool is naturally moisture-resistant. It retains its insulating qualities even when wet.
• Sound is blocked much more by mineral wool, so the interior of a building suffers less acoustic invasion .
• Mineral wool will not burn until temperatures reach beyond 1,800°F (1,000°C). The insulation actually performs as a fire barrier, slowing down house fires and giving the fire services more time to get things under control.

Disadvantages

• Protective gear must be worn when installing mineral wool insulation: the tiny slivers will lodge in skin and are small enough to be inhaled.
• Inhaled slivers of mineral wool irritate the alveoli and can cause lung disease.
• There is some data which suggests mineral wool slivers in the lungs may cause cancer, by slicing DNA and causing cell mutation, in the same way as fiberglass.

The Disadvantages of Rockwool Insulation. That same quality that makes it durable also makes it an environmental nuisance. Thrown away it does not biodegrade &#; its rock. A million years from now it will still be sitting where ever it was disposed of.

It is also a health hazard. Rockwool, like asbestos is made from rocks and minerals the fibers and dust thereof have proven to be extremely hazardous. Wearing a dusk mask when using it is advisable. Rockwool is not as serious a threat as asbestos, but it is still unhealthy.

Rockwool has a high pH and nutrient solutions must be adjusted to accommodate for that factor. It is also susceptible to pH shifts which creates the need to continuously monitor the ph. Levels of your system.

Although rock wool has a high water retention capacity it has a restricted root environment and a low buffering capacity for water and nutrients. The Disadvantages of Rockwool Insulation. The water flow to plant roots may be hindered, even when the water content is apparently high.
