The Luminera Warranty
Luminera fiberglass windows and doors are engineered to last a lifetime. Our warranty reflects that confidence — providing comprehensive coverage across three categories for decades of protection.
Effective: July 2026 · Applies to all products manufactured after January 1, 2024
Fiberglass Product Warranty
Frame, sash, and structural components
Coverage Period
- Fiberglass frame and sash against manufacturing defects
- Structural integrity of all window and door frames
- Hardware components including locks, hinges, and operators
- Weatherstripping and seal integrity against air and water infiltration
- Proper operation of operable sash for the lifetime of the product
Glass Warranty
Insulated glass units
Coverage Period
- Seal failure resulting in visible condensation between glass panes
- Insulated glass unit against manufacturing defects
- Argon gas fill retention between insulated panes
- Low-E coating adhesion and performance degradation
- Glass against stress cracks from manufacturing defects (not field damage)
Paint & Finish Warranty
Exterior and interior finishes
Coverage Period
- Peeling, flaking, or chipping of the factory-applied finish
- Fading or discoloration exceeding normal weathering
- Chalking of the exterior finish beyond industry standards
- Cracking or crazing of the painted surface
- Adhesion failure of the coating to the fiberglass substrate
All three coverage periods begin from the date of installation and are fully transferable to subsequent homeowners.
1. Coverage Details
Luminera Windows ("Luminera") warrants to the original purchaser that its fiberglass window and door products ("Products") will be free from defects in materials and workmanship under normal use and service for the periods specified above. This warranty applies only to Products manufactured by Luminera and installed in residential or light commercial applications within the United States.
50-Year Product Warranty: The fiberglass frame, sash, and structural components are warranted against defects in manufacturing, warping, rotting, or deterioration for a period of fifty (50) years from the date of installation. Hardware components are warranted for ten (10) years. This coverage ensures that your Luminera products will remain structurally sound and operational for decades.
20-Year Glass Warranty: The insulated glass unit (IGU) is warranted against seal failure — meaning the hermetic seal between glass panes will not fail, resulting in visible condensation or moisture ingress — for a period of twenty (20) years from the date of installation. Argon gas fill and Low-E coating performance are covered under this same period.
30-Year Paint & Finish Warranty: The factory-applied interior and exterior finish is warranted against peeling, flaking, chipping, excessive fading, and chalking for a period of thirty (30) years from the date of installation. This applies to standard and custom color finishes applied at the Luminera factory.
2. What Is Not Covered
- 01Damage caused by improper installation, handling, or maintenance not performed in accordance with Luminera's published instructions
- 02Damage resulting from misuse, abuse, accidents, fire, flood, or acts of God
- 03Normal wear and weathering of finishes and components
- 04Damage from airborne contaminants, chemicals, or pollutants in the environment
- 05Condensation or frost on interior or exterior glass surfaces (a natural phenomenon)
- 06Breakage of glass from impact, thermal stress after installation, or vandalism
- 07Damage from unauthorized modifications, repairs, or field-applied finishes
- 08Issues arising from improper building construction, settlement, or structural movement
- 09Products installed in commercial applications beyond rated use
- 10Labor costs for removal, reinstallation, or transportation of replacement products
3. Luminera's Remedy
If a defect covered by this warranty is confirmed, Luminera will, at its sole discretion, repair or replace the defective product or component. Replacement products will match the original as closely as possible, though Luminera reserves the right to substitute components of equal or greater value if the original is no longer available. Luminera will cover the cost of the replacement product and ground shipping to the original delivery address.
This is your exclusive remedy under this warranty. Luminera is not responsible for labor costs associated with removal of defective products or installation of replacements, nor for consequential or incidental damages.
4. Transferability
This warranty is fully transferable to subsequent owners of the property where the Products are installed. To transfer coverage, the new owner must notify Luminera in writing within thirty (30) days of property transfer, providing the original purchaser's name, the property address, and proof of property transfer. The coverage period continues from the original date of installation — it does not reset upon transfer.
