solid core door

Contacted a local shop that sells doors, and told him my requirements. He quoted that they have:

"1-3/4 solid core hardboard for $83.70, weighing 80lbs"

Sounds cheaper than the solid core doors people talk about on the forum, so I am skeptical. Are there different 'fillings' in solid core doors, and what is optimal?

The prices we talk about are with hinges, mounted in a jamb and the loch holes pre drilled 150-175 delivered to the job site.

Ah okay. Do you prefer the exterior door jams or soundproofing the interior ones?

ask them to kerf and weatherstrip the jambs, add a sweep, as well as cut the door 1" longer. There will not be any space there for airflow between rooms as that's a sound leak. If too long, you can always plane the bottom as required onsite. I'm having to add MDF to the bottom of my short door to fill the gap.

Are these homemade doors much more effective than a manufactured STC 56 door such as http://www.zeronoise.com/sound_contr...h_stc_door.htm ?

I fear trying to get the workers to correctly build a proper door for my theater. I've managed to get them to figure out double decoupled walls and the drywall guy knows green glue and proper technique there... but the door worries me. These premade doors for recording studios are not cheap, but are they as/more effective than the DIY?

I've never bought one of those doors but I can tell you adding two layers of 1/2 inch MDF to a 1 3/4 solid core door is pretty beefy. Did that at curve frenzy.

You should be aware that if you have an in swinging door there will be nothing behind the Jamb to drive extra long screws into to help support the weight.

If you have an oversize rough-in you can add custom cut (finished dimensions of drywall to drywall) 2x material that cantilevers over the edge of channel and drywall. Or. downsize your door plans accordingly.

Fwiw... I used construction adhesive and lag bolts to increase the jamb thickness and make up for the additional thickness of the Channel/DW on an inswing to bring it out flush without sacrificing width in the original framing... Something like this....

that would work too, just remember to do it before the channels and drywall go up or you're looking at some nasty cutting to retrofit.

How about using a commercial rated steel framed steel door like this one from Home Depot. I have one of these at my office, which is located in a commercial shopping center. It seems pretty beefy.

That is a beefy door alright! Haven't seen anyone on these forums with something like this.

I have trouble walking through metal door frames. It's my magnetic personality.

Questions:
1. How did you fasten the layers of MDF to the door?
2. Did you use Green Glue between the layers?
3. Was the MDF the finish surface and was it trimmed anything (e.g. to cover fasteners)?
