FAQ: What Is Hybrid (Split Frame) Window Installation?

Q: What is hybrid or split frame installation?

Hybrid installation, also known as split frame installation, is a combination method that involves full-frame replacement on the exterior while preserving the original interior components. This method is typically used when:

The existing window is vinyl
The jamb extension is wood
The interior casing (trim) is custom or high-quality wood the homeowner wants to keep

Hybrid installation offers a balance between improved efficiency and preserving interior aesthetics.

Q: What are the steps involved in split frame (hybrid) installation?

1. Selective Removal

The installer removes:

Exterior brickmould
Old window frame

The following are preserved:

Interior casing (wood trim)
Jamb extension (interior ledge)

2. Cleaning and Prep

The stud cavity between brick and drywall is vacuumed and cleaned
Old exterior caulking is removed from surrounding brick or siding

3. Window Installation

The new window (without brickmould) is inserted into the opening
The window is centered with even gaps on both sides
Shims are placed at bottom corners to ensure level placement
The window is then screwed securely into the studs

4. Insulation

Low-expansion spray foam is applied from the exterior to insulate between the frame and studs

5. Exterior Finishing

The gap between the window and brick or siding is measured
Custom aluminum capping (brickmould) is fabricated and installed
Exterior caulking is applied around the aluminum for weatherproofing

Q: What are the advantages of hybrid installation?

Cost-Effective: Less expensive than full-frame replacement
Preserves Interior Trim: Keeps original wood casing and jamb extension intact
Blinds and Shutters Fit: Interior dimensions remain unchanged
