(1) Soft insulation - This is a soft, precut, fiberglass pad insulation that is wrapped with a cover and
stitched on with tie straps. It is found behind the sidewall liners in the aft cargo compartment.

come in two halves and are attached to its respective duct section with band clamp or wire lace.

大概意思就是：飞机上的气源管道有两种包裹隔离形式
第一种：软包裹，这是用一种软的、规格裁剪、玻璃纤维垫材料，用扎带之类包裹在管道上，一般在飞机后货舱的侧壁板的后面。
第二种，硬包裹，这是用一种硬的、预制,玻璃纤维夹板材料，它已经有一定形状被紧密的包裹在特定的管道部分，硬的管道包裹有两半组成，并且用卡箍或者扎带固定在管道外面。这种在龙骨梁部分比较常见。
如有不对，还请指正。
