Mainly used

The efficiency of insufficient heater with large volumes was compensated by the use of different materials complex. The situation has improved over time, and the system of materials was filled with spectacular heat -insulating materials with affordable prices and high functionality. Today, sustainable demand is based on basalt and fiberglass heaters. Mineral worthy materials include low thermal conductivity, operational long -term resource and low cost affordable for everyone, but its very structure, consisting of glass brittle threads, can become a real threat to human health. The understanding of fiberglass technologies is mainly used for underground pipelines and the foundations of buildings under construction.
