ᐅ Interior doors – The general contractor usually includes CPL (continuous pressure laminate) interior doors as part of the scope.

Hello,

We are currently looking at possible interior doors. Basically, they should be relatively plain (white).

The general contractor includes CPL interior doors from Prüm. The core is a hollow chipboard structure, so not bad at all.

What has also been offered to us:

(1) Doors from Herholz in S-design. These doors would be flush-mounted with a stop, which we like very much, but (for now) they would not be fully flush with the wall (only the frame and door leaf would be flush). However, we were warned that every millimeter the door is misaligned would be noticeable and could quickly lead to dissatisfaction.

(2) Completely flush doors using a construction where a steel frame is installed and then painted; this adds about 1.5cm (0.6 inches) to the wall, which is then plastered flush by the plasterer. With this setup, the door leaf ends up truly flush with the frame and wall. It seems that no special on-site measures are required with this construction, unlike other flush door solutions.

Any opinions on these alternatives?
Does anyone have experience with option (1) and can share?
Is anyone familiar with solution (2) and the manufacturer offering it?

Can anyone estimate the additional cost for these alternatives?

Thanks.

Best regards

It’s best to first get a quote from your general contractor (GC) for the alternative options, or to find out how much will be credited per door if you don’t have the GC install them. Also, check prices from other companies that offer doors. Then you can decide.

A quick search on some online shop showed an additional cost of around €300 (about $330) just for the door slab. We also looked at various nicer alternatives to the standard CPL doors, and we never found anything under a €300 (about $330) surcharge per door. Your option will probably be even more expensive.

Prüm is quite acceptable. We chose a similar manufacturer.

But is honeycomb core really alright? After cardboard core, it is the second cheapest option. For just a little more money, you can get corrugated core (significantly better sound insulation) or solid chipboard directly.

Yes, that’s probably the most sensible approach.

Experience with (1) and (2) would still be interesting.

Typo:
I meant to write honeycomb chipboard panel...

It reads much better. I can’t comment on the other two options, but I thought the CPL doors from Prüm were good (even though we ended up choosing Ringolit).
