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.

Superior Thermal Insulation

A double glazed unit incorporating  Planitherm glass is up to 3 times more thermally efficient than an ordinary double-glazed unit and offers significantly better thermal insulation compared to traditional hard coated low-E products:

  • · Considerable reductions in heating bills
  • · Reduces condensation on the inner pane
  • · Improved comfort with less drafts and cold spots near glazed areas
  • · Environmentally friendly solution, given the lower C02 emissions associated with reduced energy consumption
