Have you tried an auto parts store?

Cork gasket material has been used in cars since they were invented.  I haven't bought any recently, but I think it is sold both in sheets and rolls.

Cork source?

  I haven't bought any for a couple of years but I got mine on ebay.  There were a lot of sellers offering cork in rolls. I used 1/8 inch thick by about 24 inch wide rolls , they had about 8 feet per roll IIRC , Best deals were lots of three rolls in a cello pack at that time....DaveB

big box

Try a big box home DIY store? In the US Home Depot has 30 square foot packages plus 200 square foot rolls. Maybe you can find a place with a 30 square foot package or thereabouts and stretch it to cover the necessary parts of your 16x2 area.

Cork supply

I have a need for some cork sheets so this is timely for me. My local Wisconsin Home Depot has no rolls of sheet cork in stock.  Amazon has rolls and sheets in stock and while I did not do a deep dive, most of the pricing was less then the HD local site I was on

Since you are in Canada I did check Amazon Canada.com and they are showing pretty much the same in stock that on found on the Amazon USA.

good luck and have fun when you get it

I bought sheets...

I bought 12"x36" from Amazon and a supplier called Cleverbrands. They make many sizes and thickness. I was able to get sheets for both my mainline areas and yards...

I did not like the density of what the big box stores had and wanted to get as close to the Midwest cork as possible..

Hope this helps...

One thing

we found with the flooring material (2mm, 2'x3' leftover from house build) was that not only was it coarser, it crumbles and fractures more easily.  Our first yard was done with this, but we ran out, thank goodness.  It was painful to work with.

We're in Ontario.  For our second staging yard, we ordered 3/16" 24 x 48 rolls from Nasco Discount Office Products.  Excellent, quick turnaround.

We found this thin material to be sufficient for deadening sound in our yards.  We simply sand 2' long transition grades into the Midwest approaches; takes very little time with a coarse sandpaper wrapped around a wood block. 

For the club, all of our cork

For the club, all of our cork sheet has come from Amazon. 

What about considering engineered flooring vinyl underlayment?

I got myself a roll of closed-cell, vinyl, floor underlayment that I will be using for underneath my tracks when I get to that point. I know of a couple people who have used this on their layouts and swear by it. Easy to use, cut and install as well as having great sound damping qualities.

I got mine surplus from an Flooring Installer who had excess left over from a job.

Your mileage may vary....

big rolls from big box stores

@TomO: it may be a special-order item. I know Randy Seilers bought rolls, I remember a couple years ago reading about it in his blog. I am not sure what he said about it being in stock vs special order. I vaguely think he had to order it.

But that's for people who want 200 square foot portions, the OP needs much less. And not to diminish the caveats about coarseness.

Quartet Cork

I bought these four packs of 12"x12"x3/16" cork tile and they match the thickness of Midwest cork perfectly.

I have also found similar 3/16" cork tile at craft stores.

Michael's

24x48", 2thicknesses, $16 for the thick one.

To unroll it, be generous with a spray bottle on the inside of the roll

Bulk flat Cork By the Case

Dollar Store

I bought the extra cork I needed for my new layout at Dollarama, a Canadian Dollar store.

They had thin sheets rolled up (24"x 36") and thicker tiles either 12" x 18" or 12" x 12" forget how many came in each pack, I think it was two of the 12" x 18" tiles and four of the 12" x 12" tiles.

Each pack was either $2 or $3.

Not Cork; but, Homasote road bed is available, again!!!

Homasote Road bed is available again through Central & Western Homaroad Supply, if anyone is interested.  The can be reached at CWHomaRoad@gmail.com

Bangor Cork

I second agbrewer's suggestion about Bangor Cork.They have a wide range of thicknesses, widths, and lengths, including cut-to-length rolls. I've had good luck with them. https://www.bangorcork.com/shop-products/cork-products/cork-rolls-and-sheets

Cork tiles….

I have no recollection what they cost, so it might be cost-prohibitive for a large area….I bought 12x12 cork tiles made for bulletin boards I suppose. They’re the same exact thickness as Midwest HO cork roadbed…

I used it to cut triangles to put under turnouts between the two diverging outer road bed strips….

Home Depot

If you are in Canada, I ordered a pack of 5 sheets online at Home Depot. Each sheet in 2’ x 3’.

Found Some

Update for everyone. Thanks for all of the ideas!

The current best source I found after much searching is Lowe's. Criteria were: 1) Decent quality, 2) Decent price, 3) Actually in stock...

The Local Lowe's had 2X3 foot rolls that are 4mm thick and sell for $12 Canadian Pesos, before tax. They line up pretty well with the slightly thicker Midwest and a bit of sanding will get it right. I also think the cork sheets will be good for sidings/businesses with the slightly lower track height will be easy to blend but adding a nice visual effect.

Second best was Michael's. It looked and felt very similar but would have been about double per square foot.

A big complaint online about many suppliers was cracking/crumbling when unrolling. I think this would be particularly an issue with old stock not stored properly; I live in a very dry climate. So, for my unrolling I did it slowly and sprayed it liberally with a water spray bottle while unrolling. The first test piece is stretched out and weighted to dry flat. We will see how well this works though. Stay tuned.

cracking/crumbling when unrolling.

Just unroll it carefully and you should be fine. I glue my cork down with a layer of yellow glue and weight it good for a few hours. The glue soaks in and makes the cork plenty strong enough.. ...DaveB
