Why Bay & Bow Windows
Six Reasons Utah Homeowners Choose Bay & Bow
Flood of Natural Light
Multiple angled panels capture light from three or more directions throughout the day, dramatically brightening interior spaces, even on Utah's shorter winter days.
Panoramic Mountain Views
The angled or curved projection creates a wide-angle sightline that flat windows can't match. Frame the Wasatch Range, Oquirrh Mountains, or your garden in a single sweep.
Added Usable Space
Bay and bow windows project 12–24 inches outward, creating a built-in shelf, window seat, or reading nook, usable square footage without the cost of an addition.
Energy-Efficient Engineering
Each panel uses the same ENERGY STAR Low-E glass packages as our flat windows. Insulated head and seat boards prevent thermal bridging at the projection joints.
Ventilation on Multiple Sides
Operable flanking panels let you catch cross-breezes from different angles, something no single flat window can do. Ideal for Utah's dry-climate natural cooling.
Structural Integrity
Every EPIC bay and bow installation includes engineered steel support brackets, flashed and insulated head/seat boards, and proper load-bearing verification, built to handle Utah snow loads.
