EFX Spectra – Reflective Insulation
EFX Spectra Multilayer Reflective Insulation (MRI) is engineered to increase energy efficiency, provide a clean finished appearance, and simplify installation for all residential, post frame, light-guage steel, transportation, and commercial insulation applications.
The core of the product is made of a solid/flexible foam layer designed especially for EFX that allows the material to be effective at insulating while remaining highly reflective. The core of the EFX Spectra insulation is 1/4″ thick, providing additional insulation value and durability. In addition, the multiple facing combinations are thermally bonded in a unique process that provides a long term quality finish to every EFX roll. Finally, EFX insulation is thermally perforated, which provides a high level of permeability to moisture ultimately promoting its removal.
