This product specifically created for use on Dave Snow's 73ft Thrall CenterBeam Flat Cars. Works pretty good on other 73' centerbeams too!
ComfortBase is a resilient board that cushions hard concrete, yet is structural and durable enough for heavy traffic and moving furniture. The single-ply concrete flooring system is perfect for finishing basements or improving concrete slab floors, increasing the floor surface temperature with twice the insulation of wood, and reducing foot, leg and back pain caused by standing, sitting or walking on concrete floors.
Companion product asset to my Homasote ComfortBase 8ft Product and scenery assets.
