Silica Needled Insulation Lagging Felt / Batt - High temperature heat resistant and thermal insulating


1800°F / 982°C Continuous Exposure: Higher Intermittent

InSilMax™  InsulBatt™ 1800 High Temperature needled silica insulation (lagging) is fabricated from high quality Silica that will not burn and will withstand continuous exposure to temperatures of 1800°F / 982°C with excursions to 2300°F / 1260°C.

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is highly flexible and conformable.  Available in 1/8", 1/4", 1/2" & 1" thickness.

Applications for these products include thermal insulation and/or protection of equipment such as piping, valves, engine components, turbine casings, as well as affording personnel protection from high temperature plant equipment.

For 1" material tested to ASTM C177 (test density 9.98 lbs/ft2):
