Ultra™ Series Fiberglass Windows
The dimensional stability of Ultra™ Series fiberglass windows make it a popular choice for high humidity and high heat environments, such as bathrooms and kitchens.
A Frame for all Seasons
Ultra™ Series windows and patio doors stay true through almost any environment. Because it’s made from glass fibers, the frame expands and contracts at approximately the same rate as the insulated glass it holds. This puts less stress on the seals, reduces the chance for seal failure while allowing for a clear, fog-free view.
