Rainbow
(mix between the other two colors)
The Gneiss that we extract is kind of Granite and has three colors – silver-grey, golden-brown and rainbow. It is offered in its natural shape (polygonal plates) and in already shaped plates with different shapes and sizes. We offer the possibility of a special order, based on the individual sizes and shapes chosen by the customer. The Gneiss is used as road pavement and tilling /cladding/ of houses, gardens, eco-houses, exterior walls, fireplaces, floors, SPAs and luxurious hotels, aqua-parks, golf courses, vacation complexes, swimming pools and others.
Once put on its place you will never have to remove this stone, because the Gneiss is: extremely tough;resistant to wear-out, humidity, cold and heat; waterproof, with nonslippery surface.
Priceless quality is its perfect insulation and practicality – reduces unwanted heat loss or gain of temperature, by keeping heat in the winter and not letting it in during summer and decreasing the energy demands of heating and cooling systems.
