Interior Doors: Solid wood vs MDF vs Molded

C L | Posted in Green Products and Materials on

Interior doors come in solid wood, which is probably the safest, but also most expensive. Trying to discern which are the most affordable. Does someone have a good internet source for solid wood interior prehung doors whose price competes with either MDF or molded?

Interior Doors also come in MDF and molded. MDF is often suspect due to the off gassing.
Does the concern with MDF apply to interior doors, or just trim that may be cut on site and may not be sealed all four sides?
– If the concern applies to interior doors, are there any brands that are better than others?

Interior Doors also come in what is called “Molded” which are the most affordable prehund doors. Molded can be hollow or solid core. I am not able to find any information regarding these “Molded” and if there is any off gassing concern. Does anyone have any info on this?

    As long as you seal them all six sides with a low VOC paint they can't off-gass and it doesn't matter which type you start with.

    Trustile offers MDF doors that meet CARB 2 standards. They also have a door with no added formaldehyde, which is the chemical most people are concerned about.
