Planibel G is a pyrolytic, low Emissivity glass. The Low-E coating is applied on a substrate of clear float qlass by a pyrolytic process called online CVD (Chemical Vapor Deposit technology.
In winter, the aim of the coating is to reflect the heat back to inside of the building to prevent heat loss and keep the indoor climate at an even temperature.
In summer, the coating will reduce the amount of re-radiated heat into the building thereby keeping indoor cooler and comfortable.
