Technical details

DLS – Dynamic Layer Seal

Seal: two independent seal layers, which are staggered both vertically and horizontally, provide an exceptional seal against driving rain (Class E 1200 EN 12208) and offer low air permeability (Class 4 EN 12207). The Dynamic Layer Seal (DLS) protects against splash water and ensures an effective vapour barrier.

TAD – Thermo active design

Saving energy: A patented structural ribbing uses the heat energy of the room air below the base for the glazing. This increases the surface temperature on the aluminium frame, resulting in a flawless isothermal characteristic (Uf < 1.5 W/[m²K] as per EN 1007) with condensation reduced to a minimum as a result.
