That looks like a framed and ledged door with tongued and grooved solid timber battens - which is not the same as laminated. It doesn't say what type of oak it is though, which may matter if you're trying to match it to other oak, for example. Someone may well be able to identify it. Solid timber should have a much greater life as it can be readily sanded, repaired and redecorated if necessary. Though such doors may not be compatible with the aesthetic of the building as a whole, and many doors are probably changed for fashion rather than due to problems.

Veneered doors are trickier to repair due to the laminate - you can't sand out more than surface damage - but can look good, and be more affordable. The core largely determines the thermal and sound insulation, and could be a range of materials from cardboard honeycomb, to chipboard, plywood or laminated timber, and various varieties between. The more solid, the better their robustness & sound attenuation.

The veneer need not be timber though - high pressure laminates, Formic and the like, are among the alternatives but, from your post, I guess you're after a timber finish...

We have veneered doors, because SWMBO insisted on no ledges etc anywhere to catch dust and require cleaning. So I bought fire doors for everywhere; they're not that much more expensive and they are a lot more solid. Haven't had any problems but there are only the two of us and two lazy cats. No toddlers, balls or dogs.

I suppose Stefan, the first question you have to ask yourself is, do I want the doors to look the same from both sides. The answer to that will guide you down a particular construction and price route.

Posted By: SimonDrequisite bottom ventilation gap

Forgotten where I learned it - one of the PH websites, I think? But you can build in the ventilation gap concealed in the architrave above the head of the door rather than cutting off the bottom of the door. Works well.

That's a nice idea!
