Sigma produces a variety of, low emissivity, reflective facer films used for the production of insulation and radiant barrier laminates. Sigma's ability to deposit protective layers in vacuum, prior to exposure to air, moisture, and other contaminants, results in reflective that are unsurpassed in quality, durability, and longevity.


Exceptional corrosion resistance for long-lasting performance.

Protection of reflective layers from oxidation and corrosion is paramount for long lasting performance. Sigma combines its PML deposition, SigmAlOx™ Fortified Aluminum, and DryFab™ Omniphobic technologies to create low emissivity surfaces that stand up to the harshest conditions without sacrificing reflectivity.
