遮光率与隔音不是同一指标：遮光靠涂层（银胶、黑丝三层织造），隔音靠克重和密度。要求全黑遮光选'黑丝布'织造工艺（无涂层不掉渣），银胶涂层款用久会开裂脱落

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89% similarUnverified黑丝布（三层黑纱）遮光率高但透气差易发闷，涂层银胶布遮光同样好但易开裂脱落，长期使用优先选夹层黑丝而非表面涂层工艺88% similarUnverified隔音与遮光常由同一涂层实现，全遮光（遮光率99%+）窗帘多带黑丝或三层织造，通常隔音也更好；但纯银涂层遮光布虽遮光好，涂层薄硬、克重低，隔音反而弱于绒面吸音布88% similarUnverified遮光与吸音是两个独立指标：银涂层/黑丝遮光布主打遮光但材质硬挺吸音差，绒面/织物层数多的主打吸音；需同时满足应选'吸音棉+遮光背衬'复合款86% similarUnverified遮光率与隔音不等价：全遮光窗帘（遮光率≥99%）靠涂银或黑丝布层实现，这类涂层布克重低、不隔音；追求隔音应看克重与层数，追求遮光应看织造密度与遮光涂层，两者需分别确认86% similar
