PVC Arched Windows: Elegant Shape in Modern Cover

Arched windows have long ceased to be a privilege of historic mansions — today their elegant silhouettes blend naturally into modern homes. Thanks to PVC profile manufacturing technologies, arched structures have become more affordable, durable, and functional.

What makes arched windows special? First and foremost, their ability to transform a facade. A smooth curve softens the strict lines of a building, adding individuality. Inside, an arched window creates a unique light pattern: rays fall at an angle, forming soft shadows and giving the space a sense of volume.

Modern PVC systems allow for various arch types:

semicircular (the classic half‑circle shape);

pointed (with a tapering top, evoking Gothic style);

Moorish (horseshoe‑shaped, with a gentle curve);

elliptical (elongated, with a soft contour).

The key aspect is structural strength. In PVC arched windows, the profile is reinforced with steel inserts that follow the curve of the arch. This prevents deformation from wind loads and temperature fluctuations. For large openings, reinforced profiles of at least 70 mm width are used.

Insulating glass units for arches are made using a special technology: the glass is bent in a furnace at high temperature to precisely match the profile’s radius. Special seals adapted to curved surfaces ensure airtightness.

From an operational standpoint, arched windows are on par with rectangular ones: they are equipped with the same hardware (tilt‑and‑turn, sliding), feature micro‑ventilation modes, and multi‑point locking systems. Routine maintenance requires only standard PVC and glass cleaning products.

When choosing, consider:

the arch’s angle (affects insolation and view);

compatibility with the home’s overall style;

the need for additional opening reinforcement.

A PVC arched window is a synthesis of aesthetics and technology: it retains heat, protects against noise, and yet remains a visual accent capable of turning an ordinary house into a miniature architectural masterpiece.
