Fabco proudly introduces it’s W20+ in 2026. Using the same W20 frame section synonymous with minimal sightlines, durability, elegance, and now with our best thermal performance.
Fabco has worked across a number of years to perfect a modern steel window and door that is visually identical to its original W20 product while encompassing all the benefits of the latest advancements in design and technology. W20+ represents a significant advancement in hot-rolled steel thermal performance, with all design enhancements carefully concealed to fully maintain the original sightlines of steel and glass.
