36×48 Window

36×48 Window: Types, Materials & Replacement Guide

A 36×48 window measures 36 inches wide by 48 inches tall — a widely used residential window dimension for bedroom, bathroom, and secondary living space applications. The recommended rough opening for a 36×48 window is 36½ × 48½ inches, providing ¼-inch clearance per side for shimming and flashing during installation.

The 36×48 dimension appears across both single-family homes and multi-family construction, making it one of the highest-volume replacement window sizes in the North American market. Hotian manufactures this size across all major window types and frame materials, supporting both single-unit renovation replacements and large-volume project orders within the same production system.

36×48 Window Types Available

Single Hung 36×48 Window

The most commonly specified 36×48 window type for residential replacement. The lower sash tilts in for interior cleaning access; dual weatherstripping and Low-E insulated glass are standard options. Available in white and custom color vinyl, and powder-coated aluminum.

Double Hung 36×48 Window

Both sashes operate independently for flexible ventilation control and both tilt in for easy cleaning. The double hung in 36×48 is suited to bedroom and living room replacements in traditional and colonial-style homes.

Sliding 36×48 Window

A horizontal two-lite slider for locations where an outward-projecting sash is not practical. Each lite is approximately 18 inches wide. Available in vinyl and aluminum with standard or upgrade glazing.

Casement 36×48 Window

Side-hinged outward opening with multi-point locking for maximum ventilation and security. The 36×48 casement suits bedroom and living room applications where the window faces a clear exterior wall. Available in single-lite and paired configurations.
