Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.

Casement windows are safer against intruders than double-hung windows because they are extremely difficult to pry open from the outside. However, if you’re concerned about young kids or pets, double-hung windows have safety features you might prefer. With double-hung windows vs. single-hung or casement windows, you can lock the bottom sash and open just the top sash to keep children and dogs or cats safe.

Shatter-resistant glass will ensure that even with a high impact, the glass of your window panes is less likely to break. If you’re looking for a more low-cost way to prevent vandalism, the most traditional answer would be to board up windows with a strong plywood sheet. Adding security cameras is also a surefire way to ward off potential vandalism.
