Gneiss from the region of Ivaylovgrad is a top choice not only in Bulgaria, but also abroad. Here are some of its most important properties:
Fire-resistance – Gneiss is part of the group of “noncombustible materials” and has the highest A1 level of fire protection according to the EU classification.
Moisture-resistance – It has the highest A1 level of moisture resistance and a high level of tightness. It does not change due to greater exposure to moisture and preserves its parameters in cases of repeated environmental changes.
Cold-resistance – It has a high coefficient of resistance to various adverse weather conditions. It does not crumble as a result of repeated freezing and thawing.
Sound insulation – Gneiss has a high level of sound absorption, which makes it a very good sound insulation material.
Thermal insulation – It has a low coefficient of thermal conduction, which makes it perfect for thermal insulation.
Environmental friendliness – It is environment-friendly, natural material, extracted from quarries in the Eastern Rhodope Mountains.
Resistance to chemicals – Gneiss has a high level of resistance to concentrations of chemical solutions. It shows resistance to corrosion and substances that cause degradation.
Strength – It preserves its strength even when soaked with water or after being frozen several times. It shows resistance to physical violence and external mechanical influences.
ValMarg is among the companies, offering high-quality gneiss from Ivaylovgrad, which can be bought under advantageous conditions and at competitive prices.
