Unverified遮光率与隔音不完全正相关：全遮光（遮光率≥99%）的银涂层/黑丝布未必隔音，其黑科技涂层重在遮光；真正隔音靠中间隔音棉层。选购需分别确认遮光率和克重两个独立参数86% similarUnverified遮光靠的是涂层或密织而非颜色，浅色遮光布内层加银涂或黑丝布同样能做到99%遮光，无需为遮光而牺牲选深色导致压抑84% similarUnverified涂层遮光（银胶/黑丝涂层）比高密度织造遮光更彻底，但涂层长期会开裂脱落且不透气；三层高密度提花布遮光率约90%-95%但更耐用透气，追求99%全黑选涂层，追求耐用选高密度织造84% similarUnverified遮光布应选'涂层遮光布（黑胶/银胶）'而非纯织物，纯织物遮光率仅60-70%，涂层遮光布可达90%以上，判断方法是对光观察是否透亮84% similarUnverified涂层遮光布（背面白色/黑色胶层）遮光率高但不透气、易折痕开裂；提花三层编织布遮光率同样可达99%且垂感透气更好，长期使用优选后者84% similar
