Sound like a tall order for windows? Not for Vanguard Windows.
We've designed a narrow line patented window that emulates the look of traditional windows. But to make this narrow line window strong, energy efficient, and maintenance free, we married PVC with Fiberglass and created a material called FiberCore - an all-new way of making a window. The internal core of the extrusion is made of a pultruded core of fiberglass, because it's stronger than PVC, metal, or wood. And it's extremely thermally efficient.
If fiberglass is so good, why not make the entire window out of it?

Simple. Fiberglass is not a maintenance-free material; it needs to be stained or painted. To make a window out of fiberglass would mean we would have to mechanically fasten or screw the corners together, instead of fusion welding them together so they won't leak over time.

FiberCore combines the best of both worlds, like having your cake and eating it, too.
And it's only available on Vanguard Innovative Window Systems.
