Unmatched Performance

Ultrex fiberglass is 8x stronger than vinyl.  Ultrex offers superior bend and flex resistance to ensure windows stay tight and true.  Infinity windows are resistant to leaks, seal failures and stress cracks that can compromise energy efficiency and long-lasting performance.  Ultrex captures the beautiful details and profiles of wood without the maintenance.

Timeless Design…Attention to Detail

Because Ultrex is so strong, we actually use less of it in window frames.  That means more daylight and greater views outside.
