SmartShield's 3mm roll is a foil-faced foam radiant barrier, not a bulk insulator. It blocks radiant heat rather than slowing conductive loss, so it works best as a wrap over garage doors, ductwork, attic rafters, sheds and metal buildings. The 24-inch by 50-foot roll is light and cuts with scissors, which suits DIY jobs. Compared with fiberglass batts it offers no meaningful R-value on its own and does nothing for air sealing, so treat it as a supplement to mass insulation, not a replacement.

The SmartShield 3mm Reflective Insulation Roll is a thermal barrier for homes, garages, workshops, and commercial spaces. It has a foam core with reflective foil on both sides. It limits heat transfer to help keep spaces cooler in summer and warmer in winter.
The reflective surface blocks up to 97% of radiant heat. The 3mm material is lightweight and flexible, so it is easy to handle. It also protects against moisture and dust, and it can be used by DIYers and professional contractors.
