Arched PVC Windows: Harmony of Classics and Modern Technologies

Arched windows are one of the most expressive architectural elements that give a building a noble, historical appearance. Modern PVC structures allow implementing this classic shape while preserving all the advantages of plastic glazing.

Where they are used

• private houses in classical, Victorian, and Gothic styles;
• renovated historical buildings;
• country cottages and estates;
• public buildings (hotels, restaurants, cultural institutions);
• interior partitions and doorways to create a stylistic accent.

Design features

• The profile is hot‑bent using specialized equipment to precisely match the specified radius.
• Mandatory steel core reinforcement to maintain structural rigidity.
• Multi‑chamber insulating glass unit with energy‑saving coating (optionally with noise protection).
• Special‑shaped airtight seals for reliable protection against drafts.
• Hinge system adapted for the curved shape of the sash.

Available configurations

• Semi‑circular — a classic version with a perfect semi‑circular top.
• Pointed (Gothic) — a pointed shape characteristic of Gothic architecture.
• Elliptical — with an elongated arc creating a smooth silhouette.
• Segmental — an arch segment closer to a horizontal line.
• Combined — arched upper part + rectangular lower part (the most practical option for residential spaces).

Advantages

• unique architectural appearance of the building;
• increased light intake due to the shape of the upper part;
• high airtightness and energy efficiency of modern PVC systems;
• durability and resistance to atmospheric influences;
• possibility to integrate mosquito nets and ventilation valves.

Key considerations

• higher cost compared to standard rectangular windows due to complex manufacturing;
• limited selection of hardware for arched sashes;
• need for precise measurements and calculations during design;
• installation requires skilled professionals experienced with curved structures;
• large openings may require additional reinforcement of the opening.

Arched PVC windows are a successful combination of historical aesthetics and modern technologies. With proper design and installation, they will become a decorative element of the building.
