吸音性能(sound absorption)差
这是保温材料的各项参数比较:这两种材料最常见,且不含有害物质,他们大部分性能都差不多,都拥有良好的防水性,挤塑板保温性能更好,但防火级别较低
The sound absorption performance (sound absorption) misses this is the thermal insulation material each parameter comparison:These two materials are most common,and including the deleterious substance,their majority of performance is not similar,has the good waterproof character,pushes models the board heat preservation performance to be better,but the fire protection rank is low
