SmartSHIELD 20mm white film is built to handle heat like a pro. With a polyethylene foam core and dual layers of engineered foil, it forms a powerful thermal shield. The white film reflects up to 96% of radiant heat, while the closed-cell foam traps air to block heat transfer through conduction and convection. This dynamic duo helps keep your space cooler in the summer, warmer in the winter, and your energy bills lower all year long.

This high-quality SmartSHIELD 20mm white film is built to last, resisting moisture and preventing mold growth while withstanding everyday wear and tear. Its non-toxic, non-carcinogenic design is safe for any space, and with an R-18 rating, it maintains stable indoor temperatures year-round.

Looking for maximum thermal protection? Upgrade your project with our premium reflective insulation roll - designed for long-lasting performance in the toughest conditions.

Designed for easy handling, SmartSHIELD 20mm white film is lightweight, flexible, and simple to install.

FAQ

SmartSHIELD 20mm white film insulation has an R-value of up to R-18 with a single layer and up to R-25 with two layers

Yes, for optimal performance, a reflective foil insulation requires an air gap of at least 3/4 of an inch on one side.

Yes, while both reflect radiant heat, they differ in design and application. Radiant barriers are typically thin materials installed in attics to reflect heat away from living spaces, whereas reflective insulation combines reflective surfaces with insulating materials to reduce heat transfer through radiation, conduction, and convection.
