We can either employ a window firm such as Albion, or a firm which

Suggestions?

That's a bit of an ironic username?

Looking at;

https://www.albionwindows.co.uk/door...-doors-london/

Albion supply uPVC doors, but not timber doors. They've previously
supplied windows for our house, they do good work.

Are uPVC doors acceptable from the point of view of security? I think
timber may be stronger than uPVC. Am I right to think that?
