The perforated vinyl facing allows moisture to evaporate and resists cracking and fading. These flexible sheets are good for insulating large enclosures.

Made of high-strength calcium silicate, these durable sheets withstand high temperatures and are often used in power-generating applications.

Sheets with a density of 40 lbs./cu. ft. can be machined.

Sheets with a density of 55 lbs./cu. ft. stand up to heavy compression.

Flame-resistant sheets meet ASTM E84 0/0 for flame and smoke.

Often used in high-humidity applications for its low moisture absorption, this flexible paper insulation is made of inorganic materials. It’s typically used in appliances and electrical devices. Insulation meets UL 94 V-0 and UL 94 5VA for flame resistance.

The fiberglass facing on these flexible silicone foam sheets protects against highly abrasive conditions and resists tearing. Install with contact adhesive (sold separately).

Even when subjected to heavy compression, these rigid polyimide sheets won't crack. To use outdoors, add metal jacketing.

Sheets with a density of 12 lbs./cu. ft. are easier to cut than denser polyimide insulation sheets, which makes them good for die-punching applications. They are not, however, good for machining.

Sheets with a density of 60 lbs./cu. ft. are more durable than less dense polyimide insulation sheets, so they can stand up to machining. They’re often used for mold bases or press insulation.

The lowest-density insulation we offer, these sheets are made of lightweight melamine foam. To use outdoors, add metal jacketing or a coating. Seal with reinforced insulation tape (sold separately).

Sheets with kraft paper facing have added impact resistance.
