Single glazed windowsérie 4200

The high-strength aluminium window thermal break

The aluminium windows in the Sepalumic cold range offer easy maintenance, great durability and an unfailing robustness that will be able to adapt to the most rigorous climates and weather conditions.

The versatile 4200 aluminium window meets the requirements of residential and commercial projects and ensures interior comfort in all climatic zones without the need for thermal break profiles.

Thanks to its slim profiles and its meticulous design, the window can be adapted to all architectural projects with numerous shades, colours and finishes offering up to 20% more glazed surface area thanks to the concealed sashes.

With an excellent performance/price ratio and depth of range, the Sepalumic 4200 series of casement windows has everything to seduce you.

Give shape to your windows

The 4200 window is available in many configurations: fixed, single and double hung, single and double tilt and turn, fanlights, skylights, French windows and light doors with single and double sills opening inwards and outwards, composite frames.

Known for its strength and resistance, aluminium also offers unequalled aesthetic possibilities, particularly thanks to bending, which makes it possible to create curved joinery with rounded shapes.

Circular shapes, ogives, basket handles, ellipses, the Sepalumic curved cold window is a guarantee of quality and careful finishing to give your project a touch of style.
