Great purchase

Would Recommend

I bought these after always wanting them but always seen then as single windows. These are great all connected and vinyl.

Not a bad window but arrived used and dirty

Would Recommend

The window was special ordered and upon pickup it was very dirty and looked used. The box was also ripped apart. I was able to clean it up pretty good but I am very disappointed none the less, especially after waiting 3 weeks.
