PVC-u Full Opening Round Window with Double Glazed Low E and Argon Filled Glass any size from 590mm to 800mm diameter

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

Overall frame diameter made to measure between 590mm and 800mm.
Visible glass area is around 186mm less than overall diameter (The frame is 93mm either side so a 600mm frame has 414mm 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.

The hinge has a security pin which cannot be removed without first removing the handle from inside the house.

The handle also acts as a restrictor, holds the window open 150mm for ventilation as shown in the pictures and snaps down in place to lock the window, there is no key needed.

The window will be sent with the hinge fitted. We fit the handle to make sure the window works correctly but it must be removed when packaging and for fitting, there are four screws included for the handle which you can screw in with a Philips screwdriver by hand once the window is held in place with packers. Please make sure to fit the handle after packing the frame into the opening and check it opens and closes correctly before sealing in place with silicone.

Suitable for use on an external or internal 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 Kommerling. Kommerling is a market – leading manufacturer. Widely recognised as having the best and most complete product range in the market. Kommerling Systems have been installed in millions of properties.
