A timeless style.

Much more than industrial, much more than artisanal: this is Made in Sidel.

CLASSIC window

Look at the past with modern eyes.

The Classic window has round shape both inside and outside, commonly called baroque. It is a window designed to fit in a refined and classical environmental, but revisited in a modern way. In fact, the window is built to meet all the performance requirements of a current window. This line of windows has been designed in a modern key to respond to the ever more recurring requests for classic furniture revisited and updated; in fact, many designers have managed to make a restyling of the classics in combination with modern design, thus launching the fashion of the modern baroque style.

Classic window a unique and refined style.

Interior design furnishes the home according to a rich and precious taste. In this context we find the Classic window, perfect for the natural and veined wood stains but excellent in open-pore white lacquers where the wood grain can be glimpsed under the coloring, or even more in the brushed treatments that enhance the refined line and elegant.

Baroque style.

The Classic Window differs from the Leader series for Baroque work both inside and outside. This process makes the Classic window a sought-after piece of furniture with a strongly vintage design. Classic window is available in all woods and finishes.

Special finishes.

With the new opaque water-based paints, the colors become even more natural, enhancing the univocal beauty of wood. To enhance even more the classic style of the Classic Window it is possible to create colors with an antique effect, applied on precious woods like lamellar oak, perfect thanks to its natural veins.

Furniture accessory.

Personalize your home with the classic style. For lovers of perfectionism it is possible to create internal wooden thresholds to be applied under the Classic Window. With the use of internal threshold, we not only improve the beauty of the room but energy saving is improved, avoiding the thermal bridge between the internal and external environment.

High performance glazing.

Despite its classic form, Classic Window does not give up on performance. Like all Sidel frames, it is equipped with a series of accident-prevention glass both on the inside and outside.
