Thermoguard systems guide

Approved Product Systems

Some Thermoguard products are part of a tested system and must be used together. Where a product system is shown below, the correct basecoat and topcoat combination is required for the specification we would certify.

Important: Certification depends on the correct full system being used, the correct substrate, and the correct application rate. Buying one product alone does not automatically mean the full fire-rated system has been achieved.
