Meridian | Rectangular, Balanced Diagonals
TuffX
The Meridian family is designed for the way spaces are actually built. Its rectangular format follows the natural shape of kitchen extensions, side returns, and open-plan layouts — while diagonal glazing bars maintain visual balance across the span. The result is a roof lantern that feels proportioned rather than stretched, delivering structured light and architectural presence in spaces where square designs don’t quite fit.
