Advice on Window Frame Measurements Please.....

[beckandcall]

Although my house was fully double glazed when I moved in , there is 1 small wooden frame in the upstairs wc. As it is small, I intend to replace it with a upvc frame and fit it myself. I have measured it from brick to brick as per advice on other threads but the only problem I can see is that the height measurement will take into account the old sill. When I order the new frame, do I need to order it minus the thickness of the new upvc sill ?

Any help on this would be much appreciated as I have never fitted a window frame before.

When you order the window make sure you tell them that the total height measurement you give them is " including the cill " and as long as you have measured from the brick/stone at the bottom to the brick/stone at the top you will be ok.

Thanks for that

Don't forget it is normal to knock off around 10mm from the measurements. This is to allow for any run out in the brickwork, unlike wooden frames you can't plane a bit off to make it fit or level.
