So, what is Stone Wool?

Also known as mineral wool, stone wool is created by spinning molten rock and minerals with steel slag to create a candy floss-like product. Volcanic rock is abundant in supply because it is continually being replenished by the earth’s crust. Further benefits for the environment can be found when choosing a manufacturer that has a recycling process in place. The physical structure of stone wool insulation cause tiny pockets of air to become trapped thereby achieving the optimal temperature in a home, whatever the time of year and whatever the weather. Being made from volcanic rock makes stone wool non-combustible and capable of withstanding temperatures in excess of 1,000 degrees C.

Noise Reduction
Its manufacturers claim that stone wool insulation has added benefits in terms of absorbing sound as it reduces sound vibrations. Its increased density is achieved by an open porous structure and the random direction of its fibres. This non-directional formation successfully traps sound waves and reduces sound energy.

Its benefits seem endless. Once installed, stone wool insulation purports not to degrade over time, not to attract water and to be vapour permeable. And to top it all, stone wool insulation provides no food source for vermin and does not encourage growth of mould, fungi or bacteria.

Additional Benefits

When it comes to handling and installing stone wool insulation, it is claimed that you can save time and secure a better fit more easily than with rigid alternatives.
It is quick and simple to cut and fit, and floors and walls are less likely to slump or sag.

Furthermore, it is widely available, and often backed up by technical support.
