Reflective Insulation Roll 16″ x 50ft (3mm) Foam Core Radiant Barrier

Upgrade your vehicle or home with Miuwauer’s premium reflective insulation roll. This 16″ wide, 50‑foot long sheet is constructed from 3mm closed‑cell polyethylene foam, double‑sided with high‑reflectance aluminum foil that reflects up to 95% of radiant energy. The dual‑layer design keeps interiors cooler in summer and warmer in winter, improving temperature stability and reducing HVAC load.

Installation is straightforward: simply cut to size with scissors, then secure with nails, glue, or spray adhesive. The moisture‑resistant foam acts as an effective vapor barrier, protecting against humidity in both indoor and outdoor settings. Safe and non‑toxic, it requires no protective gear during handling.
