Track vs noise...again

Well, it is obvious that picking soundproofing is like picking a wife, everybody has different ideas.  As I mentioned a few replies back, I am now using PolyPro EPS insulation board .  This is a styrofoam product with foil on one side and clear plastic on the other.  The main plus is that it is springy, not hard like normal foam insulation or ceiling tile material.  I tried it under Realtrax and its plastic roadbed, and it did an acceptable job.  With Lionel tubular on cork, it was dead quiet.  My frame work is open grid attached to the paneled walls, and 3/8 plywood on top of the grid.  The other main plus is that it is inexpensive, around 9 bucks a 4X8 sheet.

Personally, I'd be leery of the carpet foam underlayment as it has too much "give". Seems to me that, like insulation, the more you squish and flatten it out, the less effective it becomes as a sound deadener.

Mark - did you ever try to paint or apply glue and ground cover to the carpet pads ?

 

Yes, the underlayment is "squishy." Good point.

Whatever method works for you is best.  A lot depends on what your goals are scenery wise.  I like the classic postwar era layouts with green grass, plasticville buildings or going with the year round Christmas theme with Dept 56 buildings and such (have several from A Christmas story series that Sears carried years ago).  But for now its floor layouts.      Mike the Aspie.

Tru'dat! The only difference is ... I can throw away the wife. Underlayment, not so much. (only kidding)

Hello Dave (smiling as I recall 2001 A Space Odyssey, and a certain Apple Macintosh commercial).

Of note is the incredible dryness of a Laramie winter.

2001 is one of my favorite movies (And I love all 4 books.).  Wish I had know you were in Laramie, could have said hi this summer while I was there visiting my grandparents (They live about 7 miles north of town.).

As for sound, I was reminded how decent my setup is as I put FasTrack on tile floor for around the tree, and even with the 3 car train as slow as it can go, it is very loud and I have to turn it off just to talk to someone in the same room.  I need to get around to making a Christmas tree loop like I did my layout top, but then I have to find a place to put it.

Sinclair is a big name here, as you know. I toyed with the idea of modeling the Sinclair refinery,  but decided it was way too much for my modest talents. 

If you come again, or when you come again, stop in and we will run some trains!

Dr Joe & CALNNC,

    You can see why I liked the acoustical ceiling tile so much now, it was solid with some give to it, does an incredible job, unfortunately it is not cheap any more.  I got mine free when Westinghouse left East Pittsburgh years ago, it was finally falling apart after 30 years, so I discarded it.  I am going to look at Home Depot for the PolyPro EPS Insolation, if CAL had good luck with it, I may try it.   Cal can you drill thru this Poly Pro EPS Insolation without it totally degrading?  DR Joe I can't go the squishy backing route for what I need to accomplish engineering wise, my 2nd and 3rd levels need to sit on 2x4 type Trestling, the squishy stuff will not work.  Hoping the PolyPro EPS Insolation will be firm enough to do the job.

Thanks much guys for the recommendations

Never worry about what other people think, be strong and walk in the way of the Lord.

CALNNC, Lowes sells a product called Insulfoam R-Tech. I believe it is the same EPS insulation product as Home Depots PolyPro. It is the type of foam made from thousands of little white foam balls. They add a sheet of foil to one side and a sheet of plastic for a vapor barrier to the other. The foil makes it difficult to cut with a hot knife, but it may help as a ground plane for Lionel command system if a ground wire is attached to it. It cuts with any type of knife, but then sheds the little static charged balls that cling to everything. At one time you could buy 4 x 8 sheets without the facing but I haven't seen it sold like that in a long time, other then the pre-cut pieces that fit between wall studs. Does what I'm describing sound like the same thing. I still have a long way to go on my basement layout and may try substituting with this instead of Homasote sandwiched between plywood.
