help needed - new upvc windows and doors

[mase001]

hi guys,

Me and my other half have just bought a new house and basically, the seller has got his mate to fit new windows and doors but hasn't completely finished the job. The actual windows and doors are in, but there are gaps around the edges of them all - almost as if there should be clip on pieces of plastic or something? I have no idea what these bits are called and describing them to people is bloody difficult as well.

Any help is much appreciated.

Either add ons if the windows are slightly small. Minimum size is 15mm. Or upvc trims from places like eurocell

Expanding foam and trims. Eurocell for both, they have branch's everywhere.
Get a proper foam gun! the diy cans are uncontrollable and will go everywhere
