Vermiculite is a naturally occurring aluminum-magnesium silicate mineral, non-toxic and environmentally friendly. It is easy to work with woodworking tools. Moreover, it can be sawn, drilled, and sanded.
Vermiculite boards provide fire resistance, insulation, and thermal stability. Normally, they are tested to withstand extremely high temperatures and can be used to cover fireplaces, line openings for wood burners, stoves, heaters, and other heat-producing appliances…
If you decide to line your fireplace opening with vermiculite boards, we highly recommend the Vitcas shop as they specialize in providing refractory and heat-resistant products. We have consulted the Vitcas technical team and after inspecting laboratory data sheets for burning and testing our Bio Container, they confirmed that this board is suitable for lining your opening. The vermiculite board can be ordered on their website.
