 What is Perlite? The Mineral alternative

Perlite is a natural, non-flammable, non-toxic volcanic rock, which is created when liquid lava comes together with water when oxygen is not present. The original form of perlite sand is the natural glass obsidian. though it is found worldwide, there are differences in its Quality. Vital to good quality is the combined water of crystallitation, of which between 2 and 6% is combined in perlite sand. The higher this percentage is, the more the raw material expands whe heated. As the water is released, countless small bubbles form in the liquid rock, These couses the volume to increase by between 10 an 20 times – a process creating a light sand with a well-defined capillary structure. For Klimasa-Perlite plaster we primarliy us raw Perlit from the greek island of Milos. Containing 2 to 5% water of crystallisation, this Perlite sand has the ability to expand enormously. In our Special ovens, the raw Perlite is expanded at over 1000°C. This expanded Perlite is composed of 70% Silicon dioxide an is therefore a natural glass. By evaporating the water, cavities (capilllaries) are created, which allow the material to offer high quality insulation as well as regulating dampness an noise. This granualted Perlite is proven to contain no toxic materials. It is frost resistent , odourless, has high capillary Action am does not burn.

In conclusion, Klimasan-Perlite is a natural insualtion material with outstanding Features:

  • A comfortable and healthy indoor climate
