​PLANITHERM is Europe's leading energy saving window glass and is the most efficient glass available. It uses advanced coating technology to reflect radiated heat back into the room, rather than allowing it to escape through the windows. At the same time, PLANITHERM captures warmth from natural daylight by allowing it to pass through the glass.

The result? – A more comfortable, lighter, brighter, warmer and more energy efficient home that saves you money on costly energy bills. Thanks to PLANITHERM advanced thermal insulation which is 3 times more efficient than single glazed windows and at least 25% more efficient than most double glazed windows.

​Eliminate Condensation

PLANITHERM helps to virtually eliminate internal condensation and reduce draughts and cold spots in and around windows

What Is Energy Efficient Glass?

A staggering 26% of all domestic heat loss escapes through the windows. Installing energy efficient windows with PLANITHERM glass can save you money on your heating bills when compared to standard double glazed windows and frames.

Research has shown that many homeowners assume that all double and triple glazing is equally energy efficient. In fact, there are huge differences in performance of different glazing configurations and it is the glass that makes the difference.
