All Rainbow windows contain Planitherm glass. This is the most energy efficient window glass available. Planitherm uses advanced coating technology to capture free energy from natural daylight to help heat the home. A double glazed unit containing Planitherm glass is on average 40% more thermally efficient than standard non-coated double glazing.
