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.
