Plaster window frames

I have just had new double glazing installed and there is a gap where the old wooden frame was. The new window frames are thinner than the wooden.
Most people have wooden frame/facing round there to hide this.
I would like to plaster it to the window for a neater finnish.
Can this be done?
Do I need to insulate the gap first?
I also had a window removed and a french door installed and there is a 10mm difference between where the window was at the top half and where the wall had to be cut at the bottom half for the door.
Whats the best way to fill and finnish this off?

Thanks in advance

Hard to tell exactly your problem but it sounds like - if you fill the gaps with expanding foam first, let it set trim it down with a knife then skim over it.

I have sent pics to admin so hopfully you'll see my issue.
How thick would the plaster have to be for the skim to not crack on the foam?
This gap shoulld have been filled by the fitters. Ideally it should be plastered, but for convenience and to avoid spoiling the decorations, they normally fill a cover piece over the gap.

I would get them back to cover this, and when you next decorate, pull the strips off and plaster the gap flush to the frame.

You don't need foam, just use some one coat

I didnt want the finnish on the windows as I personally dont like it. I prefer the plaster to the window thats why they didnt do it.

I thought about one coat thanks for confiming that.

Is it OK to put one coat on about 10mm thick?
