Achieve passive house standards using 75 mm profiles

The highest energy efficiency standards are a key feature of the latest WICONA window series. WICLINE 75 TOP’s highly innovative ETC Intelligence® thermal break zone ensures highly effective thermal performance equivalent to stringent passive house standards.

WICONA’s WICLINE 75 TOP is a window system which is equivalent to passive house standards in energy performance. It combines ease of fabrication and the unrivalled quality of conventional aluminium window systems with a 75 mm frame depth and the highest levels thermal performance from one single system.

T = High levels of thermal insulation
O = Optimum performance and fabrication
P = Passive house standards

The new ETC Intelligence® thermal break zone ensures Uf values for the glazed unit/frame combination can be as low as 1.0 W/m²K as a result of an intelligent combination of materials and design – with no additional inserts for insulation

ETC Intelligence® means:
▪ Low Emission foil to reflect heat emissions effectively
▪ Low Transmission insulation webbing material to keep heat transfer to a minimum
▪ Low Convection insulation profile fins to minimise heat loss through convection in the thermal break zone

Other key features:
▪ Uw values in line with passive house standards
▪ Uf value improvements of up to 0.3 W/m²K for visible sash/frame combinations
▪ Uf value improvements of up to 0.6 W/m²K for concealed sash/frame combinations
▪ Concealed sashes are sufficiently robust to accommodate glazed units up to 50 mm
▪ Insertion frame with 44 mm insertion strengt
▪ Improved insulation support for structural connections

Thermal performance:
▪ Uf = 0.79 to 1.3 W/(m²K) for fixed glazing with outer sightline from 48 to 155 mm
▪ Uf =1.0 to 1.2 W/(m²K) for sash/frame combination with outer sightline from 74 to 142 mm
▪ Uw value below 0.80 W/(m²K)

WICSTAR DPS system hardware:
▪ High quality concealed fixings with a direct positioning system (DPS). Components can be installed in any order. Sash weights for concealed hinges of up to 160 kg and for surface-mounted hinges of up to 200 kg

System combinations:
▪ WICLINE 75 TOP window is fully compatible with WICLINE 75 windows, WICSTYLE 75 doors and the current WICTEC façades using insertion frames
