A compelling feature of an operable glass wall is its ability to improve your home’s indoor air quality while reducing reliance on traditional mechanical ventilation usage (central air-conditioning) – reducing energy costs at the same time. The following is an excerpt from the US Environmental Protection Agency’s – Guide to Indoor Air Quality: “While remodeling or improving the energy efficiency of your home, steps should be taken to minimize pollution from sources inside the home, either from new materials or from disturbing materials already in the home. In addition, residents should be alert to signs of inadequate ventilation, such as stuffy air, moisture condensation on cold surfaces, or mold and mildew growth.” With an operable glass wall installed in a home, it provides a fast and easy means to completely open an area and allow for fresh air to circulate and do so at a much greater rate than a typical French door or sliding patio door. The indoor air quality (IAQ) of your home is more important than one may realize. Prospective homeowners today are increasingly concerned about the indoor air quality in their homes. Pollutants like mold, radon, carbon monoxide, and toxic chemicals are receiving greater attention as poor indoor air quality has been linked to a host of health problems.
