IDEAL 4000

The bestseller among affordable windows. The IDEAL 4000 profile series combines the modern technology with the highest comfort of living. Proven solid, durable construction which you can use for the larger building projects. Classic design and parameters are ideal for the regions with moderate climate and mild winters. Thanks to the reasonable price, it’s an ideal choice when you want to save on the purchase of window joinery.


The classic, elegant lines in slim profiles with clear contours guarantee timeless elegance. If you are looking for unique possibilities of creating their windows, take a look at the Round-line series  – where you can choose between a standard straight or rounded sash. Various types of glazing beads allow for additional styling of the window and matching the character of the interior. The universal IDEAL 4000 system works well both in modern architecture of single- and multi-family buildings, as well as in case of renovations. In the latter case, where it is often impossible to enlarge the window opening, there is a particularly important advantage: the reduced height of the frame and sash which increases the area of glazing and allows more light to enter your rooms.
