PVC-u Fixed Round Window with Double Glazed Low E and Argon Filled Glass any size from 500mm 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 500mm and 800mm.
Visible glass area is 106mm less than overall diameter (The frame is 53mm either side so a 600mm frame has 494mm 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 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.

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

4 Comments on “uPVC Fixed Round Window – Double Glazed | White, Rosewood, Light Oak, Anthracite Grey, Black

  1. Ordered a 59cm round upvc window in Light Oak finish with obscure glass to replace a rotten frame in porch. Came well packaged and, helpfully, together with a range of plastic packers and a tube of matching silicone sealant. Perfect fit for 60cm opening. Very happy.

  2. Top quality product. Extremely well made. The colour we chose was an exact match to our current windows which are anthracite grey. Great value for money.

  3. Window arrived today, very well packed, love the window top quality, came with packers and good quality silicone. Just need to fit it now. Thank you so much.

  4. Excellent well made product at a very reasonable price.
