It is used in the construction industry, plastics, paints and coatings.It has the following properties: Glazed and closed surface, does not soak up water, has high mechanical strength, high abrasion resistance, excellent insulating properties.

Additional advantages: low-dust, non-flammable and environmentally friendly.

Stability of the material without time limitation - expanded perlite is 100% natural rock in terms of its chemical composition, which ensures its durability. Performance characteristics do not change over time. It will last for more than 50 years without losing its thermal insulation properties. Remains stable in the building structure throughout the life of the building: it does not shrink and prevents cracks from forming.

High strength - the cellular structure is formed by melting materials, characterised by high strength at low density. Granulated GRANUGLASS is 10 times lighter than water, so it stays on the surface. The strength characteristics do not change over time and do not deteriorate when exposed to an aggressive environment. When used in building mixtures, it forms an elastic structure in the product, so that the resulting materials can withstand high deformation loads and have increased abrasion resistance.

The spherical shape of GRANUGLASS provides significant benefits

Granular GRANUGLASS
thanks to its low density and spherical shape, reduces production costs.

GRANUGLASS is a product with a closed porous structure, which gives it an almost zero absorbability. The surface of the perlite granules is coated with a vitreous crystallisation, which prevents the ingress of moisture. The water absorption of granulated perlite is lower (0.5%) than that of crushed foam glass (5%).

The spherical shape of GRANUGLASS provides significant advantages. As a loose fill, it perfectly fills even uneven and curved voids. When used as an additive to building mixes makes the product easier and more convenient to use. The spherical form of the granules facilitates its application and even distribution in mixtures.

Low thermal conductivity
low thermal conductivity GRANUGLASS, thanks to its gas-filled cellular structure, retains heat and cold perfectly. Gas, it retains heat and cold perfectly, being an excellent thermal insulation  material.

Sound insulation - thanks to its gas-filled cellular structure, perlite prevents the passage of sound. Thanks to its spherical shape, it distributes itself evenly in the thermal and acoustic insulation layer without deteriorating its properties.

Chemical and biological resistance - chemically resistant material. Does not cause mould. Unfavourable environment for the proliferation of parasites, rodents and plants.

Easy - granulated GRANUGLASS is lightweight, making it particularly suitable for insulating beams and old building structures. The lightweight material is easy to work with!

Environmentally safe - granulated GRANUGLASS is non-toxic, odourless, does not emit dust and does not cause skin irritation or allergies. Made from natural volcanic rock. Fully recyclable. Disposable without harming the environment or human health.

Fire-resistant - GRANUGLASS is a non-flammable material and does not emit gases or fumes when heated. Application temperature from -200°C to +600°C.
