ThermaBlend® Shield

A lightweight self-adhesive composite with targeted thermal protection.

ThermaBlend® Shield is an exclusive technology from CTA Acoustics, providing versatile, localized thermal protection. Our patented, ultra-lightweight composite is an alternative to traditional metal heat shields, perfect for heat-resistance in tight areas and on irregular surfaces. ThermaBlend® Shields are constructed of a unique blend of needled fiberglass and polyester with a high temperature adhesive, an aluminum foil layer for heat dissipation, and a high-tack pressure sensitive adhesive (PSA) backing for ease of attachment.

ThermaBlend® Cross-Section

Our patented technology consists of a composite of materials that provides ultra-lightweight, targeted thermal protection.
