SF 600 Vermiculite plates 5 piece 500 x 300 x 30 mm Also like chamotte, vermiculite is designed as lining in fireplace stoves and fireplace inserts. Due to the high temperature resistance (fireproof) and very good insulation, the material is used as an inner lining in combustion chambers. The plates can be easily worked with a jigsaw, skill saw or fox tail saw (hand saw) and cut precisely. Also perfect for ovens for which no spare parts are available in the store, even if this stove had a chamotte liner before, this material can be used as a replacement. Technical data - Classification temperature: 1100 °C - Gross density: 600-650 kg/m³ - cold pressure resistance: 4.5 N/mm³ – Material is not flammable. Weight: approx. 2-2.5 kg.
