I recently had a conversation with a customer about the choice between hollow core and solid core interior doors. I thought it might be useful to share my thoughts on this subject. The following is a list of comparisons that may help guide with your decision.
Durability:
Common sense would dictate, with little dispute, that the s.c. (solid core) door will have an extended life beyond that of a h.c. (hollow core) door. The question would then be how much longer the s.c. door will last, as compared to the h.c. door. I’m unaware of any studies on the subject but, in my opinion, there is not enough difference in lifespan to warrant the added expense for the s.c. door.
Sound Transmission:
It may be a bit counter-intuitive but, since sound is transmitted through a material by vibrations in that material, it would then make sense that the hollow space in the h.c. door would offer a buffer from the vibration passing from one surface to the other.
Feel:
I have long preferred the more substantial feel of the s.c. product. The subliminal message that speaks of quality of construction cannot be understated in my opinion. That consideration aside, I appreciate the ability for fingertip closing that the additional weight of the s.c. door provides as well. Because of room air pressure variances, more effort is need to securely close the h.c. units.
Expense:
For obvious reasons, the s.c. product is the more expensive door. If you are a first time home buyer or otherwise very budget conscious, then the h.c. door is a fine alternative to consider. If, however, you are building a more upscale home, the s.c. product may be a better choice. As a percentage of the total cost of the home, the cost difference between the h.c. and s.c. doors is fairly insignificant.
