Is the ultimate window frame material for new construction and fiberglass replacement windows. Because it's made of glass fibers, it expands and contracts at the same rate as the insulated glass it holds, thereby putting less stress on the seals, reducing the chance for seal failure and creates a clear, fog-free window that lasts for years and years.
All of our fiberglass windows withstand the harshest weather yet look like traditional painted wood windows. Milgard offers the option of custom colors applied at the factory, all custom made to your home's exact specifications at no extra charge, and no extended lead time. Custom hardware finishes are available from our wide selection of hardware finishes and grid options. And, all Milgard fiberglass windows are covered by our Full Lifetime Warranty with Glass Breakage.
