Lightweight Fillers

Stikloporas JSC is a manufacturer of white expanded glass of the highest quality, also known as granulated foam glass. Company’s headquarters and manufacturing facilities are located in Lithuania, in Northern Europe. High quality specialists guarantee stable operation of factory 24 hours a day 7 days a week. The company focuses on the production of expanded glass granules since 2009.Granulated expanded glass Stikloporas – is the innovative, ecologically valuable material made from recycled glass. Porous, organic aggregate is processed when recycled glass is milled, mixed with blowing agents and melted down in extremely high temperature. Expanded glass granulate is unique for its granules ‘structure, as this allows to keep air closed inside the pellet. This technology is known as the most developed one, which demonstrates the best thermo-isolating and sound-isolating features. The variety of fractions of expanded glass allows a very wide application. It can be used in agricultural sector, automotive, machinery, oil and gas, biofiltration sectors and more. Granulated expanded foam glass is widely used in construction as a loose product for thermo-isolation or it can be used as a component part of the following products: dry mixtures, light concrete, blocks, finishing plates, drainage, products of stone mass, sound insulation products, fire-resistant products and etc. Company is constantly investing in technology, scientific researches and product development in its own laboratory and working together with best technical universities in Europe. The experience that has been gained allows the company to improve the highest level of technical support for customers as well as to provide the possibility to make customised products.

 

Low coefficient of thermal conductivity. The foam glass granulate detains warmth due to the structure of granules - the fine pores inside the ball lock the air inside. Therefore, the thermal conductivity rate is between 0.04 to 0,06 W/m* K.

Resistance. Foam glass granules are resistant to compression from 1.5 to 2.3 MPa. This feature does not change during maintenance period and even in full humidity.

Fire-resistance. Constructions with foam glass are more fire-resistant. The chemical composition of the main component is just simple blown silicate, consisting of the molten highest oxides, that do not evaporate or burn. The operating temperature regime of foam glass granulate is 200°C to 750°C.

Humidity resistance. The unique structure of the foam glass granulate prevents absorbing more than 10% of water from total volume even if it is completely immersed in water. This happens due to the pores inside the granule. It is very important that water absorption does not increase with time and the material maintains all the initial thermal insulation characteristics and stability.

Chemical and biological persistence. Foam glass granulate is completely resistant to the impact of organic and nonorganic chemical reagents (the only exception is fluorine hydrogen acid that is used to melt glass). Foam glass is resistant to the biological impact; it does not decompose or decay. None of the known biological microorganisms has the possibility to exist in it.

Purity. This nonorganic material is completely friendly to the environment, because it is simple glass according to its composition. When in use, and under the effect of changing temperatures or humidity, no chemical elements are generated.

Durability. The exploitation period of the foam glass granulate is indefinite. There are 50 year-old buildings demonstrating that the foam glass does not allow humidity to penetrate. The primary characteristics is maintained throughout the entire operation of the building.
