Despite the excellent thermal insulation the new products achieve outstanding values for light transmission and solar factor. The latter makes possible high solar energy gains in the colder months of the year. For large windows or those that face south, additional solar control is often required in order to prevent overheating of the building in summer. For this purpose AGC Interpane offers the product "iplus Energy N". It has a special silver coating that reduces the solar factor. At the same time, daylight transmission, colour neutrality and reflection are optimized. The product variant "iplus Energy NT" is temperable. All iplus low-e products have the green building certification "Cradle to Cradle Silver".
"Super-warm glass" offers effective thermal insulation, high daylight transmission and solar energy gains.

Triple glazing for passive houses and anyone who wants to save money
In the "super-warm glass" segment AGC Interpane offers the products "iplus top 3", "iplus top 3C" and the radiation-optimized high-end product "iplus 3 LS" together with the temperable version "iplus 3 LST", which are certified for passive houses. In combination with an outer pane made from clear float glass iplus 3LS, for example, achieves a solar factor of 63 percent and a light transmission (Tv) of an excellent 74 percent. So warming solar rays pass through the glass relatively unhindered but the "return route" for valuable heating energy is blocked. With an argon filling the glass achieves a low thermal transmittance (Ug) of 0.7 W/(m2K). With krypton gas a value of 0.6 W/(m2K) can even be achieved.
AGC Interpane now offers a new product range for thermal insulation.

Coating against condensation
The better the thermal insulation of a super-warm glass, the greater the likelihood that when the humidity is high and in the early morning condensation sometimes forms on the outside of the windows. This is normal. It occurs because the warmth from the inside of the building no longer reaches the outer pane, which therefore remains cold. The moisture contained in the air condenses visibly on the cold window, just like it does when it forms dew on grass that is still cold from the night. In order to maintain a clear view to the outside AGC Interpane therefore offers anti-fog glazing with a pyrolytic layer that helps to prevent the build-up of condensation: the variant "iplus AF top" provides high thermal insulation, and effective solar control is offered by "iplus AF Energy N".
