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

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