Arched windows and round arched windows

Aluminium round arched windows made to measure

Arched windows, such as round arched windows or segmental arch windows, are often chosen for historical buildings, where it is important to keep the traditional architectural style. But arched windows also stand out when they interact with modern architectural styles, particularly in properties made of natural stone: There is something exclusive about the contrast between modern and classic.
Round arched aluminium windows give you many design options in terms of shape and design, while still maintaining the excellent performance features of heroal window systems: heroal arched windows made from aluminium offer you excellent sound insulation and burglary protection as well as the best thermal insulation with U-values of up to Uf ≥ 1.3 W/m2K.

What are the differences between segmental arch windows, basket arch windows and pointed arch windows?

Segmental arch windows, basket arch windows and pointed arch windows are different shapes of rectangular, arched windows. Basket arch windows have a gently curved, half-circle arch at the top, which makes the window look subtly more elegant. The arch of segmental arch windows is even a little more curved, which lends a romantic aesthetic to any building style. The round arched window shows the greatest curving, it also lets plenty of light into the room. Pointed arch windows are not round but pointed in the arch. They attract attention with their tapering triangle in the upper window area, reminding us of the Gothic era.

Round arched windows made to measure


Each of the arched windows, including the circular "bullseye window", is individually bent using heroal's in-house bending and folding service, which is unique in the industry. This service makes it possible to produce precisely fitting window profiles very fast and in accordance with your individual requirements – both for the building shell and the interior. This also allows us to respond to the manifold requirements and needs in the best possible way. You also benefit from heroal's coating expertise: The profiles of half-circle windows are available in all RAL colours and the shades of Les Couleurs® Le Corbusier. They can also be powder-coated in various gloss levels. With heroal SD coating technology, you can also refine your round arched windows in striking looks, such as concrete, rust or wood.

Opening variants of round arched windows

The opening variant of the window has an impact on the supply of fresh air and sunlight, and thus also affects the way the residents use the window: Round arched windows are suitable for all opening variants in new and old buildings. These include fixed window sashes, turn sashes to the left or right, and tilt/turn sashes that you tilt and open to the left or right. It is also easy to combine turn or tilt/turn sashes with fixed window sashes in order to accentuate special visual aspects.

  • What about the energy efficiency of heroal round arched windows?

    Thermal insulation plays an essential role not only for living comfort, but also with regard to resource-efficient construction. heroal arched windows ensure the greatest possible thermal efficiency and achieve U-values of up to Uf ≥ 1.3 W/m2K.

    The high thermal efficiency is due to heroal’s compound system applied to the aluminium-plastic profile that hardly emits any heat, and the geometry of the insulating strips in the window, significantly reducing heat conduction. This insulating strip technology is patented, and currently far exceeds the requirements of the German EnEV regulation.

  • Are round arched windows secure?

    Burglar-resistant windows, whether rectangular or round arched, are indispensable not only during the holiday and travel season. It is important to consider which resistance class from RC 1 to RC 4 is suitable for your windows, regardless of whether they have a rectangular, half-circle or round shape. The police recommend a minimum protection of resistance class RC 2 for windows. Round arched windows from heroal are certified up to resistance class RC 3 and withstand perpetrators using simple tools, an additional crow bar and simple drilling tools for at least five minutes.
