Do you want to keep your horse clean and comfortable in their stalls?
MP SHEATH R-1.3. 1/2x4x8 insulation boards made by Georgia Pacific is the product for you!!! They are a little firm but squishy like rubber mats, cover most of the stall and level the footing and best of all keep your shavings from mixing with the red dirt.
Lowes caries them for 8.65 each. 2 are enough to cover 1 stall!! They are light and fit a any standard trailer for transport.
