Color Your Flame

Roka Refractories produces refractory bricks in hundreds of designs, as well as a variety of colors such as yellow, black, red, brown, and white firebricks, covering every need and special preference of the world market. With a sales network of more than 46 countries, and more than 2,000 customers worldwide, Roka Refractories is ranked as one of the most powerful European refractories industry in the world.

About Us

With extensive experience in meeting the needs of the global market, Roka Refractories is a company that combines innovation, quality, and competitive pricing policy by investing in economies of scale.

Innovation: We are the first company in the world to produce Brown firebricks. Following this success, we managed to win over the global market, by being the first company in the world to produce black firebricks. Every new innovation embraced by our customers, is an incentive for us to bring new materials to the global market, covering needs even before they are created.
In 2019, Roka Refractories was evaluated by the European Union, in the EU GATEWAY program, as one of the 40 dominant companies in the field of construction and new technologies.

The culmination of our success, besides our wide range of products, is the creation of a completely new patented, ecological, pressed firebrick, which breaks all the laws of natural science. In particular, the ceramic connection is made without the use of fire, with the same properties as common firebricks in terms of mechanical and thermal resistance, saving the planet and future generations by more than 1,184,833 carbon dioxide emissions per year.

Quality: We follow all ISO protocols for the production process and our products comply with the standards of ASTM as well as EN. We provide certifications for contact of firebricks with food, for the lack of any carcinogens, as well as radioactive residues. Through these certifications, from independent international companies, our customers are able to feel completely safe about their choice.

Economy: How does a European product compete directly in terms of pricing with Asian and the Eastern companies? Τhe answer to the question is simple, technology. We follow all the developments of technology and robotics in our industry. This allows us to constantly invest in new developments and state-of-the-art machinery, as well as produce smarter and faster by investing in economies of scale. In combination with our choice to be a verticalized company, mining our raw materials with our own material and technical structures, we provide you with the stable quality of Roka Refractories products at the most competitive prices on the market.

Lavamix is a high-temperature refractoriness material that can endure up to 1200⁰C. It is a mix of primary ingredients that can be found in nature, which we were able to mix with our technological infrastructure in order to provide the best possible result.

Fire boards are special refractory clay boards whose heat resistance meets or exceeds 1200°C. They are made of silicoaluminate clays and calcium-based binders and they are used as inserts in metallic stoves (fire backs) and fireplaces.

Roka Refractory Mortars constitute a turn key solution in a fireplace’s or a barbecue’s construction process. Our mortars are, in fact, a mixture of special refractory cement and a variety of fireclays which results from the firebrick production process.

Fireclay is the dominant raw material in the production of firebricks. Roka Refractory possesses its own quarries, in different locations in the Balkans.
After careful elaboration, we abstract useless elements to offer a clear and qualitative material to our customers.

Insulating Firebricks are whitish in color and light weight. They are made of mullite, a product of aluminum and silicate after exposure of refractory clay in high temperature.

Ceramic blanket is an insulating material, easy to install, which contributes to the thermal insulation of the combustion space of industrial kiln, fireplace, stove, barbecue, bread / pizza oven.

Roka Refractory

Expanded clay is produced from special plastic refractory clay with no or very little content of lime. The clay is dried, heated and burned in rotary kilns at 1100–1300 °C.

Roka Refractory

It is a natural material that comes from volcanic explosion. It is light weight and insulating material as well. It can be used for many applications such as barbecues, pizza ovens, flooring, contraction, production of cement based decoration materials and cement blocks.

Fireproof Material

A refractory mineral is a mineral that is resistant to decomposition by heat, pressure, or chemical attack. It most commonly refers to a mineral that retains strength and form at high temperatures. Refractory materials are used in furnaces, kilns, incinerators, and reactors.
