The Milgard® Ultra™ Series, as the name implies, is the ultimate window frame material for new construction and fiberglass replacement windows & doors. Because it’s made of glass fibers, it expands and contracts at the same rate as the insulated glass it holds. This puts less stress on the seals, reduces the chance for seal failure and results in a clear, fog-free window that lasts for years and years.
