Warranty Claim Tips

  • Most insulation warranties are essentially material warranties — labor is almost never covered
  • Spray foam warranties require installation by a certified applicator
  • Keep your energy audit or blower door test results as baseline documentation

HomeScore Pro Tips

  • Insulation rarely fails within warranty — the bigger risk is improper installation reducing R-value by 20–40%
  • Rockwool is the only major insulation brand that doesn't degrade from moisture contact
