Thermo aluminum - slide SSI-128

Thermo aluminum, a specially designed thermal barrier or "thermo bridge" in the middle section, provides maximum thermal insulation and strength: about 1.87 W/(m•K), the thermal conductivity of windows, and sound insulation: ≤ 39 (-1; -3) dB decibels (depending on the thickness of the glass). It also provides airtightness and high wind resistance.
