Hot Water SystemHot Water System

Electric Tankless Water Heater Energy Efficient- Energy is not wasted in keeping water

heated, it is used to heat water on demand Simple Design Easy Installation

Window and Frame SystemWindow and Frame System

Window similar to Serious Window’s 1125 Series foam insulated fiberglass frame with dual pane glazing

and three low Solar Heat Gain (SHG) films The 1125 Series has a U-Factor of 0.13 and a SHG

coefficient of 0.20. The R-value of the frame set is R-11 and combined with the window, the R-Value has a rating of R-7.1

Window and Frame SystemWindow and Frame System

Why Fiberglass? High Strength-Because it is fiber reinforced it is

extremely resistant to warping and corrosive materials, works well for large openings

Insulator-Fiberglass is 800 times less conductive than other frame materials such as aluminum allowing for no thermal bridges to occur

Maintenance Free

Living in the Midwest should not eliminate us from forward thinking and Sustainability.

While this concept is intended to pass before a panel of international judges in Europe, the intent is p j g p ,to remain affordable and practical.
