Cork has been the sub-roadbed material of choice for decades. It's all-natural, clean, provides an appropriate rise to create a ballast profile while helping to deaden the sound.
This product is 6mm thick and is used for O scale track applications. Rolls are unique in being able to deliver long, sweeping curves without traditional joints. Unlike strips, rolls do not have a bevel edge. The slope of the ballast profile is created with a bead of caulk. Use a thin, steep application for highly groomed mainline tracks and a thicker, wider application for older or less-well maintained lines.
A single roll is slightly longer than 48-feet. Laying two strips side-by-side will produce 24-feet of roadbed from a single roll. Strips are 1.125" wide and produce a roadbed 2.25" wide.
Rolls allow roadbed to be shipped more economically than long strips! Four rolls (96 feet of roadbed!) fit in a single 14x14x4" box that doesn't require excess size shipping rates.
