GRP v solid wood external

[graemezz]

I am looking at replacing an old upvc front door with something else.
GRP I see is a sub-version of composite and cheaper. How easy is it to fit locks to it rather than solid wood?
Which is stronger grp or 44mm wood?
Someone said fixing multi point lock to grp is fiddly.

If the difference between GRP and composite door is the GRP is a foam core whilst the composite is a solid timber core then i'd prefer a composite just for strength, however I'm confused about why you want to fit multi point locks to them when 99% already come with them already fitted, just curious

The ones i saw seem to be plain like https://deal4doors.co.uk/products/grp-colonial-6p-white. Maybe if you spend more it comes with pre-fittings.
Thank you

That's an internal door surely?

Defo external but seems to be a door with nothing on it
