Help finding window trim

[TheFew]

Hi,

I need to find some right angled plastic trims to tidy up an old window (shown in the below picture). The aim is to cover the old wooden window surround and cover the gaps between the surround and the plaster.

The trims need to be around 1.2m long, 100mm deep to cover the old timber and have a right angle section that is 40mm long to cover the gaps between the wood and the plaster.

Having had a look online I am struggling to find a suitable product (not really sure what to search for).

Can anyone provide any guidance on the sort of product I need?

Thanks

Use a fascia board with neat mitres at the corners

Phone your local window company and ask for PVCu windowboard covers. They will be able to supply you with what you need.
