When daylight systems embedded in roofs become more extensive, good thermal insulation is increasingly essential.

The byword here is highly energy-efficient daylight systems.







Key aspects in energy efficiency are technical development and material-related factors in both the type of glazing used (for instance, thermal insulation glazing with coefficients of up to 0.6 W/ [m²K]) and in support structures. It is a question of optimising isothermal processes to such an extent that thermal bridges are eliminated.

A LAMILUX component known as a "Thermo Active Design TAD" uses patented structural ribbing to take advantage of the heat energy in room air underneath window bases to increase the surface temperature on the aluminium frame. This ensures a flawless isothermal process (UF < 1.5 W/ [m²K]) and provides very effective insulation.

The "IsoThermal Load Converter – ITL" also optimises isothermal processes by transmitting the bearing load from the daylight system into the supporting structure. As a consequence, the base profile is freed of loads and stresses, thus enabling materials with excellent heat insulation properties to be used. The ITL ensures the whole system is transformed into a thermally optimised interlocked structure with torsion-proof statics.

The Dynamic Layered Seal (DSD) features two separate seal layers, which are offset from each other both vertically and horizontally and ensure the system is perfectly air-tight. This seal protects against splash water and provides an effective vapour barrier.
