Thermal Insulation Classification

In Simple Terms

When teams add thermal insulation (heat-protective material) to car parts, if it's permanently attached through methods like welding or bonding, it's legally considered part of that component itself rather than a separate add-on. This affects how the part is classified and regulated under the technical rules.

• Thermal insulation permanently attached by riveting, bonding, welding, brazing, or plating becomes part of the underlying component
• This classification matters for technical regulations and component homologation
• The attachment method determines whether insulation is considered integral or separate
• Teams must account for insulated components in their overall design and weight calculations
