Clera Windows + Doors

I was delighted by the service provided by Clera windows when they replaced my existing windows. I was looking for good looking windows with a high R value and Infrared+UV blocking.
We immediately noticed a difference once these windows were installed. The room where we had three replacement windiws installed suddenly became easier to heat/cool. The old windows, although supposedly energy efficient, were base builders' grade and made it difficult to control the heating and cooling in this south facing room.
I was so pleased with Clera that I have ordered 5 more replacement windows from them.
