As recommended by our contractor Tamarack Windows and Doors (excellent installation) we chose sturdy black exterior / white interior “Aspekt 1800” windows.

This is a great company who went above & beyond with their support. My order was affected by the industry’s supply-chain issues (due to COVID) but the team at Glasshaus made a big effort to complete the job and ensure my project was a success. Excellent customer service that you can’t find at many other places. My door and window look great and are super solid as well. I would definitely work with them again and recommend to others.

Wow is the first thing that came to mind after these windows were installed! They look and perform amazingly. Jim gave us many options to choose. We had extra coatings added because our house faces east/west and the sun can be intense. We were very surprised at how well these coatings work keeping the heat of the sun out. The triple seals make a big difference in the noise from outside.
