Bifold help

[alicetripp96]

I am after some advice. A friend of ours is a ‘builder’, he built our extension inc these bloody bifolds which quite frankly I wish he hadn’t. As you can see the fitting from the external (posted below), I need some help on trimming in the gaps. Any ideas?

Probably add some powdercoated aluminum angle trim coloured to match, got a better photo? That ones a bit crappy.

I dont have a better picture as file size is too big. Its anthracite though but the gap is probs just over an inch on left filled with expansion foam and 2 inches on right filled with expansion foam and timber?
