Yes. The substrate may be MDF, but usually the door skin is thermoplastic, thermofoil or a veneer. Michael

I'm resurrecting this thread...have a slightly different question in addition to all of the issues already discussed. I'm going to order from Conestoga I think. I'm replacing white thermofoil doors which are 20 years old and haven't really faded, but there are a few where a candle or the toaster got too close and caused some minor melting....Most people think they look nice, but in my mind they are still "cheap". The uppers are 42" I'm going to stick with white and just buy doors to match the existing boxes which are fine. Also, I have granite and it's hard to find someone willing to remove it to install complete cabinets. My question is....will a mapleframe/mdf center FEEL like a real wood door? Will it feel different than my thermofoil? I'm talking in terms of both surface and the weight in your hand as you open and close it. Will the outside edges and the panel raise etc be sharper than thermofoil? If I get mdf center will I still have the defined edges I am looking for. If you've had thermofoil you will know what I am asking. I'm toying with getting 5 peice mdf...but don't want to lose the wood look or feel... I think the mdf center is my best bet. My husband is what I like to call..anal...pretty sure he will be bothered by cracks, but he doesn't want the fake plastic look either. Pretty sure all wood is not a good choice for me, too bad because I love wood... The style I am leaning toward is https://www.cabinetjoint.com/cabinet-door/monarch-square/  but I am also toying with shaker style. Wondering if the shaker trend is headed out....Also considering doing a grey island by applying end panels. Guess I could start a new thread for those questions.

thank you guys..actually i realized that the granite we liked is not Bianco Antico but a very similar granite called Delicatus. I love it! But no matter how many searches I do online, I dont see it paired with antique brown cabinets. I have seen it with almost every other stained cabinet there is but not the stain we are choosing. DH does not want to go darker or lighter on the cabinet stain and thinks Delicatus will go just fine. Our designer is trying to push a more golden granite on us and thinks that I should stick to all warm tones...although she is the expert I somehow feel that Delicatus just might work. It has so many colors in it that I think it will compliment the brown cabinets pretty nicely. But then is the question of the flooring..Dark brown cabinets, Delicatus granite, and nutmeg stained oak floors scraped lightly. Do you think there are too many different colors going on there?

I know that this topic is getting beat to death, but I feel I must weigh in. If you are doing a painted door you be best off doing a hybrid door, maple or birch rails with a mdf center panel. The stiles and rails will be more durable while the center panel will not show lines from the stave expansions. Cracking is inevitable with the joints, however they can be so slight, that they are not visible, and you can only feel them when you run your hand over them, A flexible finish like latex paint instead a pigmented catalyzed varnish will be more flexible and be less prone to chipping in the future. Plus it is easier to touch up. If you are glazing with a hand rub method you will achieve a better look with catalyzed varnished because they tend to yield a smoother finish. If anyone thinks that a painted finish on a mitered joint with biscuits, will never show finish fractures, than they are naive! A mitered joint is the worst possible joint for a painted finish, mortise and tenon would be a much wiser choice. If the wood at a miter joint contracts then they both contract in the same direction, thus creating the possibility for a joint fracture in the finish. Montalvo, please keep in mind when Khat is talking about cracking the reference is to finish fracturing NOT joint failure. It is possible to have finish fracturing without joint failure. This is why NO door manufacturer or cabinet company would ever warranty against this. The movement of kiln dried wood can be very significant when there is even small moisture changes, With hard maple being one of the worst. If you would like I can post the chart information if you would like evidence. To think that a cabinetmaker would not be using kiln dried wood or making mitered joints without an additional joint lock is ridiculous, they would not be a cabinetmaker, they would be an amateur woodworker.
