Another perfect window
Written by Tim B. on 24th Jun 2020

These two windows arrived perfectly, and popped right in, nice and easy. This 14x21 fits pretty nicely in a regular stud bay with a shim or two. It looks great and lets a breeze in. Customer service was exceptional in providing updates about it arrival, being on backorder from the global pandemic.

better than expected.

The windows were better than expected. Great affordable window. Easy to install. The dimensions were right on. Better quality than I thought. It would have recieved 5 stars but 2 out of the 4 windows I purchased had a bent corner and were slightly bent in, near the edges at the glass but not that big of a deal I just straightened them out. Again I just installed them so I am not sure about the duration of them but they seem they will be fine. I would highly recomend the product. And shed windows was very helpful when I called asking about there products.

Prompt delivery, good quality

I was building a chicken coop for my wife, and needed an affordable window. Ordered this one, it arrived in 3 days. The install was simple and the product itself was exactly as described. Good material quality. I would highly recommend it

Great little windows!
