It is required that drums be stored and displayed in an area where there is not constant sunlight or a heat source directly on the drum. Natural skins adjust to various degrees of temperatures.  The extreme, constant heat will ruin the drum, as it dries it out too much causing it to split.  The best display manner is at room temperature in a well-lit area away from direct sunlight or heat. The drums have withstood various temperature changes in their creation and can move from outside, if used as a dance drum, back to an inside display place.
