PVC, COMPOSITE, OR ROCKDOOR FRONT DOOR

[Nicetoseeyoutoseeyounice]

I am having a new front door but am finding it very confusing as to the sheer choice on offer.
Are ROCKDOOR front doors the same thing as composite or these totally different.
Any recommendendations more than welcome.

Same, rockdoor is just a brand name and is one of the better quality ones but there are others like doorstop

The main differences are solid core i.e. timber vs foam core obviously solid being the better but if your on a budget then don't be put off by a foam core door

Thank you, I have asked this question in another post as I found it all a bit confusing, but, I have to say, although I was against foam filled, I have been reading about how wood filled can split.
My budget can stretch to a buy a little more expensive but I am unsure if the more expensive wood filled would be the right choice.
