Insulation in Wolf Ovens


  • White particles, fibers, strings, material, insulation in oven after use.
  • Is the oven insulation harmful, hazardous, damaging to one's health?
  • Is it normal to see oven insulation through the oven door glass?
  • Is it normal to see oven insulation in rack guide mounting holes or screw holes?
  • Should insulation be hanging out from corners, walls, or ceiling of a Wolf oven?


White fibers or insulation fibers can show up in all ovens, not just Wolf products.
  • This may be more noticeable in new ovens, particularly after the use of a convection mode.
    • Loose fibers may be seen within the oven glass door, rack guide mounting holes, rack guide screw holes, corners or edges of oven cavity, or oven door gasket.
    • Ensure that the proper burn-in process has been performed; refer to First Time Oven Use Burn-In Process.
    • Ensure that the oven interior is wiped clean after it cools completely.
    • Remaining fibers will dissipate with continued use; wiping out the oven cavity after each use will help to expedite this process.
  • Small fibers of the insulation are not directly harmful or hazardous; however, direct skin contact should be avoided to reduce irritation.
    • Formaldehyde is not used in Wolf oven insulation.
  • Insulation is also visible through vents on the unit.
  • If large gaps within oven insulation can be seen, or if oven insulation is freely hanging from sections of the oven cavity or oven door, no further troubleshooting advice is available.
