SULKO ProfiAl Aluminium Window

These windows match requirements of customers with high demands on top design and energy savings.

Outstanding thermal insulation – Aerogel

The product range of ProfiAl contains a multi-chamber thermal bridge completely filled with Aerogel which improves the already very proficient parameters of the profiles even more and thus pushes them even closer to perfection. The final thermal insulating properties of this profile range, therefore, tend to appeal to customers of the highest demands for thermal insulating elements. As a consequence, the product presents the perfect alternative for both energy-sustainable and passive houses while having the heat passage coefficient of Uw 0,77 W/m2K as the perfect proof of it all.

Quadruple glazing

Quadruple glazing ensures the ultimate thermal insulating system of the profile together with HeatMirror glass with embedded foil and as a result, to reach even more enhanced thermal insulating properties.
