These products can directly contact with fire, characterized with high temperature resistance, lightweight, low thermal conductivity and good energy saving effect. Compared to the traditional "galvanized plate+ insulation cotton" duct, Wanhao lightweight insulation brick has the following advantages.
Wanhao lightweight insulation brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature.

1. The energy-saving effects of lightweight insulation brick can be increased by 10% to 15%, having more advantages than the traditional products on energy-saving and insulation aspects
2. Compared to traditional products, the new lightweight insulation brick’s service life extends three times.
3. When contacting burning fire, lightweight insulation brick is non-smoking and non-toxic gases being released.
4. When lightweight insulation brick used in construction, no condensation water produced, sealing effect is much better.
5. At the same time lightweight insulation brick can reduce 5 to 10 decibels noise.
6. Lightweight insulation brick can shorten project duration 3 to 5 times, reduce 20% project cost
7. Lightweight insulation brick’s output up to 120,000 pieces / day, assure prompt delivery.
8. Manufactured as per ASTM standard

Above all, compared with traditional products, Wanhao lightweight insulation brick from insulation effect and environmental protection aspects is more advantageous and it has low cost and strong seal . Applied in smelting furnace, firing kiln, flue, refining apparatus, heating apparatus, reproducing apparatus, gas stoves and pipes, soaking furnace, annealing furnace, reaction chambers, and other similar industrial heat treat equipment.
