Know What You’re Buying—Anatomy of a Window

Understanding the terminology when purchasing new windows will help you determine the best option for your home and your budget.

The Options!

Full-Frame Replacement

This involves removing the entire window unit right down to the rough opening in the wall. You’ll see the studs and inside the wall cavity.

When to do a full-frame replacement

  • Most comprehensive option
  • Necessary when the existing frame is damaged, rotted, or you want to change window sizes
  • Insulation is not up to par
  • Fear of moisture intrusion

Considerations

  • This method is a bit more labor-intensive and more expensive
  • It’s the most effective way to ensure the window is insulated correctly and properly flashed
  • Addresses underlying structural issues and allows for complete customization.

Pocket Replacement

Also called an insert replacement, the new window fits inside the existing frame.

When to do a pocket replacement

  • The existing window frame is level and in good condition
  • Your home is relatively new and is well-insulated
  • A desire to restore historic millwork

Considerations

  • Minimal access to add insulation
  • If the frame is not level or is damaged, or the window will not function as it should
  • You’ll lose some glass area since the new frame sits within the existing frame
  • Minimal disruption to interior and exterior finishes
  • Unable to flash/seal the outside to today’s standards

The bitterness of poor quality
remains long after the sweetness
of a low price is forgotten
