Classic Series


Classic window features a moulded frame movement on both sides, commonly referred to as baroque. It is a classic-inspired window revisited in a modern way.
It is designed to meet the needs of those who desire timeless furniture with a modern twist. Classical, highly evocative windows now find new life through specific processes that make them modern and performing. Perfect in natural and grained wood stains, excellent in open-pore white lacquer finishes where the wood grain is clearly visible under the coloring, or even more in brushed treatments that enhance its refined and elegant design.

Baroque workmanship

Classic window is characterized by baroque style, a workmanship that results in a refined design and vintage-inspired piece of furniture. Classic window can be made in all wood species and paints.

Special paints

Thanks to water-based opaque paints, colors look even more natural. It is also possible, if desired, to choose colors with antique effects, even on fine woods such as glued-laminated oak.

Furniture complement

Upon request, Sidel can realize wood internal thresholds to be applied to the base of Classic windows. Choosing to use window stools increases energy savings, effectively avoiding thermal bridging between the indoor and outdoor environments.

High-performance glass

Despite its design, Classic window does not sacrifice its performance. In fact, like all Sidel windows and doors, it is equipped with accident-prevention glass on both internal and external sides.
