Super warm glazing serves as an energy source

New iplus 3LS: Top transmittance values At the glasstec 2010, Interpane presented new developments and optimised glazing products for architectural as well as solar applications.

One of the highlights at the trade fair was the new triple insulation glazing iplus 3LS with its top notch transmittance values. Interpane was able to increase the solar factor to 63 per cent and the light transmittance to 74 per cent. In terms of appearance, the “super warm glazing” features excellent colour neutrality (Ra,D = 98-99).

Windows that have modern triple insulation glazing are a requirement for highly efficient low-energy and passive houses. These days, they are also increasingly used for renovations, since their insulation values are almost as good as those of a solid brick wall. With two significant advantages, however: They let precious passive solar energy gains and light into the house. The new Interpane “super warm glazing” now uses solar radiation even more effectively than before and produces high solar energy gains during the heating period and the transitional periods.

With the help of new functional coatings, the new iplus 3LS features a thermal insulation value (Ug) of 0.7 W/m²K (with argon filling), a solar factor of up to 63 per cent and a light transmittance (tL) of up to 74 per cent. While the warming sunlight passes through the glass quite unobstructed, the “return path” for the thermal heat is mostly blocked off. This also increases one’s living comfort: Even on cold winter days, the temperature on the glass surface inside the room will nearly be the same as the room temperature, thereby eliminating the “cold touch” that still exists with double glazing.
