Fullback Siding

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
  • Reduces the heating and cooling energy loss through the walls by up to 20%
    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
