“With the new ‘S 7000 IQ Passive House’ window system, GEALAN assemblers can round out their product range and at the same time – thanks to the powder-coated skirt– extend the available range of colours.

The advantages of S 7000 IQ Passive House:

• High-insulating window system: thanks to the cladding, U_w-values of 0.80 W/m²K can be achieved. With the right glazing, U_w-values as low as 0.61 W/m²K can be achieved.
• Various possibilities: the components of the S 7000 IQ series can be combined with passive house windows. Not only single lights but also meeting stiles, mullions and transoms are possible.
• Wide variety of colours: a wide variety of colours are available thanks to the special coating of the aluminium shell.
• Elegant optics: thanks to the avoidance of a sash-encompassing frame, the profiles affect a more slender appearance.
• Excellent impermeability: the four encompassing gaskets ensure an optimal seal against air drafts and driving rain.

Reducing heating costs in the private sector is one of the major goals recently pursued by lawmakers. Guidelines such as those dictated by the German Energieeinsparverordnung (energy conservation act) flesh out the requirements that the construction must fulfill. Thus the trend in Germany and Western Europe has gone from standard to low-energy houses and finally to the passive house.

Since a passive house does without traditional heating systems, optimal components are vital. The most important element is the appropriate window.

The leading German testing centre, the Dr. Wolfgang Feist Passive House Institute in Darmstadt, has tested and certified the new S 7000 IQ Passive House. The uninstalled test window meets the required norms with a tested U_w-value of 0.80 W/ m²K.

System description

'S 7000 IQ Passive House' window system, GEALAN

S 7000 IQ Passive House windows consist of frames made out of vinyl profiles, high-insulation cladding profiles, thermal breaks in the steel stiffeners inside the frame, standard steel reinforcements in the casement for high structural stability as well as triple glazing with a U(g)-value of 0.7 U_g = 0,7 W/m²K (4/16/4/16/4). Four layers of gaskets ensure an optimal seal.

Calculated values:

• U_f = 0.79 W/m²K
• psi = 0.026 W/m²K with spacing element “Swisspacer V”
• U_w = 0.80 W/m²K for the non-installed window with standard dimensions (1.23m x 1.48m) and pane value of U_g = 0.70 W/m²K
• U_w = 0.84 W/m²K for the installed window in three standardised sizes
