PVC-u Fixed Round Window with Double Glazed Low E and Argon Filled Glass any size from 450mm to 700mm diameter

This is a customisable listing. You can choose your size, frame colour and glass type when ordering.

Overall frame diameter – 450mm to 700mm.
Visible glass area – 100mm less than overall diameter (The frame is 50mm either side so a 600mm frame has 500mm of glass).
The frame has a 70mm depth into the wall.
The glass unit is 28mm thick and meets current UK building regulations for conservation of fuel and power.

Suitable for use on an external wall. If you are replacing an existing window you should order 10mm smaller than the brick to brick opening to allow clearance which can be filled with silicone.

e.g. A 600mm window would fit in a 610mm brick to brick opening.


For our Low E glass we use Thermaglas. Thermaglas is the most thermally efficient double glazed unit in Europe and combined with argon gas will perform 145% better than a standard double glazed unit and 60% better than Pilkington K used by most suppliers which means lower heating bills. It also reduces condensation by up to 3 times that of a standard glass unit and eliminates cold areas around windows.

(Comes with a 10 year guarantee against failing)

For our PVC-u Profile we use Spectus. Spectus is a market – leading manufacturer. Widely recognised as having the best and most complete product range in the market. Spectus Systems have been installed in millions of properties. Cheaper profiles will turn yellow over time.

The PVC-u Profile and Glass Unit are both manufactured to BS Kitemark European Standards.
