The IBS temperature controlled damper system automatically adjusts the temperature room by room and is easy to install, cost effective, and can be installed in existing or new construction, the company says. The patented system does not sweat, thus eliminating mildew problems and rust, and it opens in increments as to how much air or heat is called for, thus maintaining a constant comfort level and eliminating the highs and lows in existing forced air systems, according to the company.
