Needled Silica Insulation. InsulBattÃ¤ 1800 High Temperature needled silica insulation is fabricated from high quality Silica that will not burn and will withstand continuous exposure to temperatures of 1800Â°F / 982Â°C. This material resists most acids and alkalis and is unaffected by most bleaches and solvents. It is highly flexible and conformable.
And on top of that, it generally costs less than granite and quartz. Letâs take a look at the finer points. First of all, soapstone is the most heat-resistant countertop surface available. Thatâs why itâs commonly seen in laboratories and settings where heat resistance is of the utmost importance. One thing that make this a great choice in kitchens is the fact that it conducts heat poorly.
