Our round windows are formed from our custom thermally broken system. The system has been specially designed to bend easily without distortion.


All joints are welded and dressed flush so that no joint lines can be seen.


All fittings are silver finish as standard but other colours are available if required. All our round windows are internally beaded for security purposes unless otherwise requested.

Powder Coating

Single Colour

Our frames are finished with a polyester powder coat using a wide variety of colours.

Dual Colour

We also offer a dual colour option, which allows the outside of the frame to be a different colour to the inside.

See the Finishes page for more details.

Window Types


Fixed aluminium circular windows can be formed into smaller and larger diameters than opening ones (see table above).

Opening (Horizontal Pivot)

Fittings for our aluminium circular pivot windows include an adjustable friction hinge with a built-in 15 degree restrictor stay and reverse position catch.

The reverse position catch allows the window to be turned 180 degrees, enabling both sides of the window to be easily cleaned from inside the building.
