Bay Windows

A bay window is a set of windows joined at angles so the unit projects out from the wall, creating a shallow alcove inside and more glass and light than a flat window. Crateworks builds bay windows as an assembly of thermally-broken aluminum casement and fixed units, made to your opening for renovation and replacement projects.

Bay Windows spec into Maison Collection, and Farmhouse builds. Multi-tag products are shown with the same canonical URL across every look they appear in.

Common questions

A bay window is several windows joined at angles that project out from the wall, so the unit forms a shallow bay inside and gathers light from three directions. It is built as an assembly, typically a larger fixed or casement window in the center with angled units on each side.
Yes. A bay is built from individual units, so you choose which open. A common setup is a large fixed pane in the center for the view with casement windows angled on each side for ventilation. Crateworks configures the opening units to your needs.
This configuration is positioned for renovation and replacement projects while we close out additional certification. The thermally-broken aluminum casement, tilt-turn, fixed-picture, awning, and arc-top configurations are NFRC certified today; we are sequencing the rest of the line through the same path. Tell us your project and we will confirm what we can document before you commit.
