Why Garden Windows Are Not Energy Efficient

Interested in a garden window?  Garden windows are far less energy efficient than conventional windows. Why? First, let’s define what a garden window is.

A garden window is essentially a five-sided glass box that protrudes from your house as much as two feet.

The reason why garden windows are not very energy efficient is because they can utilize as much as twice the amount of glass for the same size window opening than would a conventional window. Glass, no matter how well-sealed or filled with gasses, is a notorious energy waster.
