  • Extira panels can be carved, routed and machine well.

Environmentally Friendly Panel Product

  • Made from sustainable materials: No old growth wood is used in the manufacture of Extira panels. They are made from wood that is of no commercial timber value and is the byproduct of other operations.
  • No added urea formaldehyde: This is certified by Scientific Certification Systems under certificate number SCS-MC-01802.
  • Complies with CARB: Extira panels are acknowledged by the California Air Resources Board’s (CARB) Airborne Toxic Control Measure (ATCM) 93120 to utilize exempt status ultra-low emitting formaldehyde (ULEF) resins.
  • Contributes to green building programs: Extira panels contribute to industry green building programs such as LEED and the National Green Building Standard.
