Why Do Some Window Grilles Have a Bump?

Have you ever noticed window grilles that extend outward instead of lying flat? This design, often called a “belly,” serves more than just an aesthetic purpose.

Traditionally, window grilles provide security by preventing intruders from easily accessing windows. However, curved bars offer additional practical benefits:

Space for Planters – The protrusion creates a ledge for flower pots, allowing homeowners to add greenery and charm to their windows.

Support for AC Units – In older buildings where air conditioners are installed in windows, the bulging design provides extra space for ventilation while maintaining security.

If you’re considering installing window grilles, look for durable materials like wrought iron or steel. Many home improvement stores and online retailers offer various designs to match your home’s style. Professional installation ensures they function safely and effectively.

While window grilles enhance security, they work best alongside other protective measures like strong doors, alarm systems, and exterior lighting. Next time you see curved window bars, you’ll know they’re both practical and stylish!
