just been reading a few of the topics and came across the one in regard to fixing C track and one member mentioned using purchased corrugated material from Noch.
As an underlay for noise reduction on any size layout would work out to an expensive way of noise reduction, would it not be cheaper and easier then to go to your local large appliance store and ask them for several large empty cardboard boxes that get recycled and then to use them as noise reduction materiel, these can be cut to any size for any layout and can be painted to match any colour scheme and are very easy to fasten to any module or table top.
even easy to remove the creases caused by the corners of these boxes Just slice the of with a decent SHARP knife and then lay the cut section next to each other, has to be much more user friendly and POCKET friendly then having to purchase this sort of material.
Even when one decides to redo a layout then remove used cardboard to the recycle yard and start with fresh from the local store.

I was one to go out and purchase five large sheets of Cor-flute from a local frame manufacturer at some considerable cost to my pocket and now having thought about this i will be going out this coming weekend to source several Large cardboard boxes from my local GOOD Guys store and I know that they will gladly give them to me as i have previously gotten a cardboard box from dishwasher for our kittens to play with for free.

Is this stuff similar to what is used for display boards and land agent signs? The stuff I am thinking of is flat both sides but has a core consisting of tubes in a honeycomb fashion (best way I can think of to describe it). Real estate agents around here get their signs silk screened onto this stuff and it is rugged enough to withstand most weathers.

Certainly good thinking for light weight bases.

Apart from the cost what about what we used in the old days, good old cork?
