Planitherm glass is the most energy  efficient glass on the UK market today, enabling you to cut your energy bills by up to 28%.

  How does Planitherm glass work

By using advanced coatings to retain more internal warmth whilst capturing  energy from natural daylight. This advance in glass technology manufactured on Saint-Gobain glass UK’s ‘magnetron’ coater,  means that it is now possible to achieve A rated windows with your choice of window frame.
