Thermal insulation glass

Saint-Gobain PLANITHERM® TOTAL+

PLANITHERM® TOTAL+ is a new generation of energy saving glass. It is the most energy efficient available.

Its advanced coating technology reflects radiated heat back into the room, rather than allowing it to escape through the windows.
At the same time, PLANITHERM® TOTAL+ allows free heat and light from the sun to pass in to the room through the glass.

Saint-Gobain PLANITHERM® 4S

SGG PLANITHERM® 4S has been developed especially for conservatory glazing applications.

Offering excellent solar control properties, reduced glare and enhanced thermal insulation SGG PLANITHERM® 4S provides true year round comfort when used throughout the conservatory.

The advantages

Thermal Insulation
The advanced coating of PLANITHERM® TOTAL+ reflects heat back into the room. By using a 4-16-4 Argon Planitherm Total+ IGU, you can
achieve a U-Value as low as 1.2 W/m2K

Optimal Energy Ratings
PLANITHERM® TOTAL+ Enables a window frame to achieve an “A” Rating in the Window Energy Rating scheme (WER).

Free Solar Heat Gain
PLANITHERM® TOTAL+ uses advanced coating technology to capture free energy from natural daylight to help heat the home. By using a
4-16-4 Argon Planitherm Total+ and Low Iron IGU, you can achieve a “Solar Factor g” of 0.74

Reduced Haze & Tint
PLANITHERM® TOTAL+ maximises the amount of natural light into the home, without the haze or tint effects associated with some older
double glazed windows. By using a 4-16-4- PLANITHERM® TOTAL+ and Low Iron IGU you can achieve 81% Light Transmittance.

Reduced Condensation
PLANITHERM® TOTAL+ helps to virtually eliminate internal condensation and reduce draughts and cold spots in and around windows.

U-Values For PLANITHERM® TOTAL+ Double Glazed Units

Thermal Transmittance
The values represent the amount of heat lost through glazing therefore, a lower U Value (W/m2K) is a better option for energy efficient glazing.

Light Transmittance
These values represent the amount of light or glare which gets through glazing. A lower percentage is a better option for roof glazing.

Energy Transmittance
These values represent the amount of solar heat which gets through glazing. A higher g factor is a better option for achieving Window Energy Ratings.
