Insulated Siding with Fullback® Technology and Fullback® Thermal Support is a structural insulation backer that fits behind and fully supports the contour of any siding panel.

Insulated Siding:

  • More energy-efficient
    • Up to 5 times the “R”-value of conventional backers
  • Better looking longer
    • No denting, sagging and warping
    • Extreme weather protection
    • PreventolTM® repels termites
  • More liveable
    • Permeable "vapor breather"-does not contribute to mold growth

All factors compare Fullback insulated siding to ordinary, hollow siding.
