Insulation Warranty & Damage-in-Transit Replacement
Two layers of coverage on every order: the NAIMA-certified manufacturer’s lifetime R-value warranty on the material itself, and Insulation Overstock’s damage-in-transit replacement policy on freight-related damage.
Manufacturer Lifetime R-Value Warranty
Every roll and batt sold on Insulation Overstock comes from a NAIMA-certified U.S. mill. NAIMA membership requires each manufacturer to warrant the stated R-value at time of manufacture — and to warrant that the material will not chemically or physically degrade in a way that lowers the R-value over the useful service life.
Damage-in-Transit Replacement
Freight damage is separate from manufacturer defects. If a bale or roll arrives with facing damage, water intrusion, crushed material, or torn packaging, the manufacturer will not warrant it — freight damage is the LTL carrier’s responsibility. That is where Insulation Overstock steps in.
We hold standing damage-claim agreements with our LTL carriers, which means you never have to file a freight claim yourself. Report the damage to us within 30 days of delivery, and we handle the paperwork with the carrier, the replacement order with the mill, and the re-shipment coordination. You get replacement material at no additional cost.
Look at every bale before you sign the freight receipt. Note any visible facing tears, water staining, or crush points directly on the driver’s BOL (bill of lading).
Take clear photos of any damaged material within 48 hours of delivery. Photos taken later may not be accepted by the LTL carrier’s claims department.
Text photos + order number to 303-594-8373 or email [email protected]. We respond same business day.
Approved replacement orders ship within 3–7 business days. No additional freight or service fee is charged. The damaged material stays with you — do not attempt to return it.
Lowest Verified Wholesale Price Pledge
Insulation Overstock’s calculator publishes the manufacturer’s actual wholesale rate. If you find a lower verifiable wholesale price on the same NAIMA-certified spec (same manufacturer, same facing, same R-value, same width), we will match it and refund the difference.
Claim the pledge by sending the competing quote to [email protected] within 30 days of your order. Approved matches are refunded to your original payment method within 5 business days.
What These Warranties Do Not Cover
Warranty coverage is specific to product defects and freight damage. The following are excluded from both the manufacturer warranty and our damage-in-transit replacement:
- Installation errors: Compression below rated thickness, wrong facing orientation, unsealed seams, missing banding on overhead runs. These are addressed in our installation guide.
- Post-installation environmental damage: Rodent, insect, or water intrusion after installation. These are building envelope issues, not material defects.
- Mid-installation damage: Facing tears from utility knives, staples, or fasteners during install. Order 5–10% extra to account for install waste.
- Modification voids warranty: Applying secondary facings, adhesives, or coatings not specified by the manufacturer will void the R-value warranty.
- Non-NAIMA product: If a supplier substitutes non-NAIMA-certified material during a shortage, warranty coverage does not apply. Every roll we ship is NAIMA-certified — verify the mill batch documentation on delivery.
