hollow core vs thin solid core, any difference?
« on: November 18, 2014, 07:06:57 AM »

I'm about to build a partitioning drywall in order to isolate a soon-to-be-bedroom from talking noises right outside the front door, I live in a condo btw.
Not wanting to spending a lot of money, at my local DIY mall I have being given basically two options: a hollow core door or a thin solid core door. Both doors in this price range weight essentially the same, 67 pounds for the thin solid core (pine wood, around 3/8 inch thick) and ironically, 75 pounds for the hollow core. Not sure how much of it is the door panel itself and how much is the outside casing.
According to the guys at the shop the thin solid core door still has better soundproofing performance but weighting less I have my doubts.
Any opinion on this matter?
Thicker pricier doors are not an option at the moment

thank you very much

Mass law is set in stone...the heavier the door the better the reduction.
to answer your question use the solid core door...a hollow door is a resonance chamber that is why it is so easy to talk through them.
I understand having a budget but you really need a heavier door if you want to be happy with the reduction.
I normally like to see excess of 150 lbs. as a minimum.
You can always add mass to the door to increase the reduction.
