Insulating refractory firebricks

Our portfolio of refractory materials

We produce lightweight insulation fire bricks with densities ranging from 400 to 1300 kg/m3.

Our portfolio includes insulating fire bricks and shapes with a temperature classification from 500 °C to 1400 °C. They use high-quality European chamotte and high-alumina raw materials with good thermal insulation.

The bricks are manufactured from dry masses on a press, allowing us to give our products almost any desired shape. Our bricks are available in rectangular form and as wedges, tiles, shapes, and large-size formats.

Compared to the most commonly available imported lightweight insulating fire bricks from Asia, our insulating bricks stand out for their higher strength and resistance to mechanical factors. We achieve high resistance by using local raw materials and applying a production method based on pressing. In the production process, we do not use burnable pore-forming additives, which allows us to avoid additional emissions of harmful gases.

The ISOLUX product line includes our insulating bricks for high-temperature industrial applications, which have a wide range of temperatures from 500 °C to 1400 °C. Despite their low densities, these products feature high compressive strength, up to 21 N/mm². They are intended for use in the insulating layer of furnace linings.

Perlite insulating firebricks

Perlite insulating firebricks

Our lightweight, unburned perlite-insulating fire bricks offer excellent insulation. They are recommended for use in temperature ranges from 400 °C to 1000 °C, enabling significant energy savings. They are available in standard rectangular formats.

In the PERLITEX line, we offer insulating bricks produced by forming and air-binding methods - without firing. This process yields a product with excellent thermal conductivity and very low density. Their typical recommended application is as the second layer of insulation in ceramic masonry.

Shapes

We can shape ceramics in any way

In the refractory lining design, flexibility and the ability to adapt the lining's shape to the specific shell and installation conditions play crucial roles. Thanks to our versatile molding department, large series reaching thousands of pieces and short runs, including a few pieces of complex ceramic shapes, pose no challenge for us.

We are involved in both the design and production of all necessary molds. For each shape, we prepare a detailed execution drawing. Over more than 170 years of activity, our specialists have developed documentation and a parts database, enabling the execution of over 35,000 shapes on demand without producing new elements.

Examples of complicated shapes we produce:

Why choose our products

We are not just a manufacturer of materials used at high temperatures; our mission is to provide customers with comprehensive refractory solutions tailored to ceramic linings of kilns. We offer over 180 tested product brands designed to meet all challenges during device lining operation.

Predictable and consistent product quality

Thanks to the multi-point quality control plan, we can ensure that each batch of delivered products complies with the established tolerance limits, regardless of the shape of the product and the size of the batch.

Polish-made insulating brick

Our insulating products are manufactured at our single facility in Poland, allowing us to offer shorter delivery times compared to the most popular insulating bricks imported from Asia on the market.

High mechanical strength of products

Compared to typical insulating products available on the market, which are relatively light and brittle, our insulating brick stands out for its significantly higher mechanical strength. This strength is even three times greater than comparable insulating bricks from Asia. As a result, our products are easier to install and provide excellent stability for the insulating layer.

Dry press method production

We manufacture our insulating products similarly to dense-structure products. We form them on a press and then fire them to obtain the final shape. This method allows us to supply standard rectangular formats, such as planting wedges and complex shapes that enable quick bricklaying in heating furnaces.

High packaging standard

We deliver our insulating products to over 40 countries across different continents. We make every effort to ensure that our products reach our customers in the same condition as they left the production line. Well-designed packaging ensures a stable bulk, allowing for the safe storage of pallets even on several levels at the customer's site.

Reliable raw material sources

In our production, we use both primary and secondary raw materials. Primary raw materials are exclusively obtained from certified and vetted suppliers and manufacturers from various corners of the globe. We generate secondary raw materials through the recycling of products and semi-finished products. Each raw material undergoes double quality control - the supplier provides the first and the second, and we conduct ourselves after delivery.

What we do at this stage?

We prepare raw materials such as aggregates, clays, and grogs in mixers to obtain a uniform mass with appropriate parameters and moisture content.

The proportions of ingredients and granulation are adjusted according to the product type and final dimensions.

What we control at this stage?

We monitor the mass's moisture content and take a sample to check the mixture's chemical and granular composition.

What we do at this stage?

We produce 100% of the molds for presses for our own needs. The dimensions of the mold are adjusted to the type of product, and later, shrinkage or expansion during the firing process is taken into account. We regenerate molds regularly after a specified number of production cycles.

What we control at this stage?

We measure the geometry of the mold and check the correct execution of details by the drawing documentation.

What we do at this stage?

Our molding park has 20 presses, allowing us to produce short and long products, ensuring uniform quality from the first to the last piece

The pressing parameters are controlled through a pressing program, considering the parameters of the mass currently being formed.

What we control at this stage?

We meticulously examine the dimensions and internal structure of the raw product through visual, ultrasonic, and destructive testing.

What we do at this stage?

Our facility has three tunnel kilns with an automated system for controlling temperatures in individual zones. The firing process is conducted at temperatures up to 1700 °C and carried out according to a strictly defined technological schedule.

Products rejected at this stage are returned to crushers and processed into secondary raw materials.

What we control at this stage?

After firing, we perform a final visual inspection, examine the geometry, and assess the product's physicochemical parameters.

What we do at this stage?

For projects requiring additional actions on the product, we offer a range of services such as cutting, grinding, marking, strapping with steel bands, or pre-assembly.

What we do at this stage?

After a successful production cycle, we pack the products on wooden pallets (IPPC dimension 1100 x 800 mm or EUR dimension 1200 x 800 mm). Standard packaging elements include interlayers on each layer, cardboard corners, PE straps, and a welded plastic hood.

Each pallet is marked with a product label containing an agreed information set and a barcode for the production batch.

What we control at this stage?

We check the quality and stability of the packaging before transferring the pallet with products to the finished goods warehouse.
