28×54 Window

28×54 Window: Egress Requirements, Types & Guide

A 28×54 window measures 28 inches wide by 54 inches tall — a dimension commonly encountered in residential renovation and egress window replacement projects. The recommended rough opening for a 28×54 window is 28½ × 54½ inches, providing standard ¼-inch clearance per side.

Egress code note: Most North American building codes require a minimum net clear opening of 5.7 square feet for egress windows, with a minimum clear height of 24 inches and minimum clear width of 20 inches. A 28×54 window in a single hung or casement configuration typically provides a net clear opening that satisfies these requirements in most jurisdictions — however, egress compliance should always be verified against local building code for the specific project location and window type before ordering.

The 28×54 dimension appears most frequently in renovation projects where the existing rough opening in the basement or lower-level bedroom was framed to this non-catalogue dimension. Hotian produces this size as a standard made-to-order unit with no surcharge for the non-standard width.

28×54 Window Types Available

Single Hung 28×54 Window (Double Hung Available)

The single hung is the most practical egress window configuration in a 28×54 opening. The lower sash slides fully upward, providing a clear opening that meets egress height requirements. Tilt-in sash for interior cleaning access. Low-E double insulated glass and dual weatherstripping standard. Available in white vinyl and powder-coated aluminum.

Casement 28×54 Window

An outward-opening casement in 28×54 provides the maximum net clear opening area for egress compliance — the entire sash opens outward, maximizing the usable escape opening. Multi-point locking hardware standard for security. The casement is the preferred egress window type where maximum clear opening is the priority.

Sliding 28×54 Window

A two-lite horizontal slider in 28×54 — each lite 14 inches wide — provides ventilation and partial egress opening in locations where an outward-projecting sash is not permitted. Note: sliding windows typically provide only half the nominal opening area for egress purposes; egress compliance should be verified for this configuration against local code.

Egress Window Considerations

When specifying a 28×54 window for egress compliance, confirm the following at order stage:

• Net clear opening area — the usable opening after deducting frame width and hardware, not the rough opening dimension
• Minimum clear height — typically 24 inches net clear in most jurisdictions
• Minimum clear width — typically 20 inches net clear
• Window well dimensions — for below-grade installations, the window well must allow the sash to open fully and provide clearance for egress

Hotian can confirm the net clear opening specifications for any window type in the 28×54 dimension at order stage.
