Stone wool is considered to be one of the best materials for heat and sound insulation and fire protection. The main advantages of stone wool include low thermal conductivity, non-combustibility and inability to support combustion, high temperature resistance, good sound insulation, resistance to microorganisms, chemical neutrality, steam permeability and water repellency.

Melting Furnaces

The vast majority of stone wool producers use coke-fired cupola furnaces for melting raw materials. In addition to this, Izotech can supply gas-fired tank furnaces and electrical furnaces. The choice depends on the current gas, coke and electricity prices at the plant site. The latest melting furnace design is the gas-fired cupola furnace, which is recommended in countries with low gas prices. Izotech can provide consultation services to help you choose the most appropriate melting furnace.

Process & Methodology

Izotech designs and builds stone wool production lines in accordance with strict EU environmental regulations IPPC. Our stone wool production lines- depending on the customer’s demands- can produce standard or biodegradable stone wool, which is standard in EU.

IZOTECH stone wool production lines range from 5 to 200 tons/day capacity (5 000 to 100,000 tons/year), and are fully automated thanks to PLC and Scada systems.

The construction of industrial plants undertaken by Izotech is based on the PDCA (Plan-Do-Check-Act) methodology. CAD/CAM & CAE are implemented during the design and fabrication of the equipment.

Simulations of the occurring processes are modeled with the CFD software covering fluid flow and heat transfer phenomena. Object-oriented modeling and simulation are also applied by utilizing OOP tools.
