Round PVC Windows: Style and Functionality in Unusual Shape
Round windows are a striking architectural element that can give a building a unique appearance. Modern PVC structures allow implementing this shape while preserving all the advantages of plastic glazing: airtightness, thermal insulation, and noise reduction.
Where they are used
private houses and cottages (attics, gables, living rooms);
cafes and restaurants (to create a memorable interior);
public buildings (decorative facade inserts);
saunas and steam rooms (as light portholes).
Design features
The profile is bent using special equipment to precisely match the required radius.
Steel reinforcement is used around the perimeter for strength.
Seals have a special configuration to ensure airtightness along the entire circumference.
The insulating glass unit is made of tempered glass or laminated glass for enhanced safety.
Available configurations
Fixed — no opening mechanism, the simplest and most budget‑friendly option.
Pivoting — the sash rotates around a central axis (less commonly around an offset axis).
Top‑hung — the upper part tilts for ventilation.
Combined — a mix of fixed and operable sections.
Advantages
unique design that makes a building stand out from standard solutions;
even distribution of light load;
resistance to wind loads due to symmetrical shape;
long service life when properly installed.
Key considerations
higher cost compared to rectangular counterparts due to complex manufacturing;
limited selection of hardware for opening mechanisms;
precise load‑bearing calculations are required for large diameters;
installation must be performed by specialists experienced in working with curved structures.
Round PVC windows are a bold design solution that, with proper implementation, will become a reliable and aesthetic element of your space.
