Vermiculite board is made from a naturally occurring aluminium-magnesium silicate layer that has been already expanded with the application of heat. This expansion process is called exfoliation and the resulting material is used in bulk form or processed to boards by a press forming process. The board can be worked easily with wood working tools. It can be sawn, drilled and sanded.rnrn***Available in different patternsrnrnKey Features:rnrn• Low thermal conductivityrnrn• Easily machinedrnrn• Stronger than ceramic fibre boardrnrnExamples of Applications:rnrn• Night storage heatersrnrn• Hearthsrnrn• Register platesrnrn• Boilersrnrn• Vessels and tanksrnrn• Fireplaces and Stoves
