Garden Window Features: A Class Above

Our garden windows are more than just a window—they are a beautiful and functional extension of your home.

A Sun-Filled Nook for Your Home

Designed to capture maximum natural light, each garden window includes a sturdy, built-in shelf perfect for creating a mini-greenhouse for your favorite plants, herbs, and décor.

Smart Design for Fresh Air & Protection

Enjoy a gentle breeze with easy-to-open side vents, complete with insect screens. The 30° sloped roof is not just for style—it’s engineered to direct water away from your home, preventing leaks and protecting your walls.

Superior Energy Efficiency & Security

A multi-point locking system and a full-perimeter gasket create an airtight, energy-efficient seal that outperforms standard windows. The durable, weather-resistant vinyl frame ensures your window is built to last, providing comfort and peace of mind in every season.

Information About Our Garden Windows

Garden windows are three-dimensional windows that project outward from the wall. Because they have glass on top and three sides, they bring more light into the living space. Many people use this space for house plants and window gardens, which gives rise to the name.

Garden windows are often found in kitchens and bathrooms or areas where more light is desired, but only a small window will fit. If you’re planning to replace an old double-hung window, consider replacing it with a Keystone Window garden window for more architectural interest.

Frequently Asked Questions About Garden Windows

What is the average price of a garden window?

Pricing depends on size and product lines. At Keystone, we offer upfront quotes —no hidden fees, just transparent value for your home.

Why are garden windows more expensive than other window styles?

These include glass on three sides, built-in shelving for plants, and venting, making them more complex than flat casement windows or standard bay window styles. Keystone uses premium materials and expert installation for lasting performance.

What’s the difference between a bay window and a garden window?

Bay windows are angled and often larger, while garden windows extend straight out with a sloped roof and side vents. Keystone garden windows add ventilation, light, and indoor gardening space—perfect for kitchens and smaller rooms.

Are garden windows a good idea for my home?

Absolutely. You’ll enjoy fresh air, extra light, and a functional interior shelf. Keystone’s models bring the utility of patio doors and the charm of display windows—all in one energy-efficient upgrade.

Does Andersen sell garden windows?

They do—but Keystone offers a better local experience. Our garden windows come with expert fit, Energy Star-rated windows, and a transferable lifetime warranty, backed by trusted service right here in Pennsylvania.
