PLANITHERM is a new generation of energy saving window glass that uses an advanced coating to retain more internal heat and to absorb free energy from natural daylight, designed for use in double glazed units. That means lower energy bills compared to standard windows but for the same cost.
Trade Windows are members of the "PLANITHERM INSTALLER NETWORK", and as such only install PLANITHERM products incorporating argon gas filling with warm edge spacer bar on their "A" rated windows.
