Design Engineering DEI 51403 Thermal Acoustic Insulation & Damping Kit - Complete Pre-Cut Interior Kit

The Design Engineering DEI 51403 is a complete, multi-piece pre-cut thermal acoustic insulation and damping kit engineered to dramatically reduce interior heat and noise. Unlike generic, one-size-fits-all sound deadening solutions, this is a fully engineered heat and sound control system delivered in a precision pre-cut package for a professional-quality result.

The kit employs a multi-material approach for maximum effectiveness across different interior zones. D-Mat ultra-lightweight insulation serves as a superior heat barrier for firewalls, headliners, and hard-to-reach areas. Under Carpet Lite provides a lightweight yet powerful heat and noise barrier for floor applications. Boom Mat 2mm Damping Material targets structure-borne vibrations, squeaks, and rattles at the panel level. High Temp Spray Adhesive is also included for secure, lasting installation.
