DEI Ultra Block is a 48" x 48" sheet of reflective, open‑cell acoustic foam with a mylar face engineered as a heat and noise barrier. It reflects heat up to 428°F, resists flame per FAR 25.856(a), and dampens sound in confined spaces like generator boxes or under‑hood areas. Aggressive adhesive backing makes installation peel‑and‑stick simple while protecting components and improving cabin comfort.
