The DEI Universal 2‑Door Vapor Kit is a cut‑to‑size vapor barrier sheet designed to block moisture, reduce cabin noise, and add thermal insulation for two‑door vehicles. Constructed from closed‑cell PVC foam with an aluminum reflective facing and adhesive backing, it conforms to irregular surfaces and replaces worn barriers to reduce condensation and vibration while simplifying installation for improved cabin comfort.
