This ASL Solutions Dog Palace is an insulated dog house, featuring up to 4 inches of real foam (Styro/EPS) insulation in each panel for optimum comfort, making it cooler in summer and warmer in winter than look-alike dog houses without insulation. The ASL Solutions Dog Palace Insulated Dog House amenities include an easy pass-through, self-closing door; a raised floor that provides a dry and warm bedding area; a sloped floor with a drain hole that whisks liquid away from your pet's living area; self-storing window panels that easily reposition from winter's closed position to summer's cross-ventilation position without tools; and, durable plastic construction that cleans up easily.
