Advantages of Rockwool Insulation
Currently, mineral wool insulation is occupying a significant place in the industry. Rockwool insulation is used for a variety of purposes.
Rockwool insulation has many advantages over other types of insulation materials. Some of them are:
- Rockwool insulation material has the ability to withstand more than 1200ºC without melting, which means it significantly slows down the spread of fire. The material has high-quality thermal insulation properties - for instance, 120mm of slabs takes the R-value up to 3.3 per inch.
- For the residents, it provides improved thermal comfort as your house will stay at desired temperatures as well as lower bills.
- Another great advantage of Rockwool insulation is the incredible acoustic properties - it helps decrease the noise coming from the exterior.
- It is highly breathable, allowing moisture and air to travel across the walls, which helps drive away the dampness from the property.
- Rockwool insulation is highly resistant to moisture and at the same time, it is also vapor permeable. It does not wick water. So, any bulk water contacting the external or outer surface drains. Simply put, the water is not absorbed in the insulation body.
- Traditional insulation materials quickly lose their R-value. However, Rockwool is different because it is made from slag and basalt, which make it resistant to fire. So much so that if you have Rockwool insulation installed, it will go a long way to prevent a fire from spreading inside the house.
