Magnetite window comparison; the window on the left has a magnetite window panel installed and the window on the right does not. It is well below freezing outside and the window with the magnetite panel is 8 degrees warmer than the window without it.
Set up an appointment on first call. Tony was professional, friendly, and courteous. Cleaned up thoroughly. They submitted a proposal for work they identified as deficient in their test. The proposal was broken out by project, so I could select specific areas.
