求翻译：在材质上，夏季使用的窗帘一般透光性要强，宜用轻薄通透的材质。绒布在欧式风格中有不错的表现，但夏天使用则嫌厚重，业主可以选择更换，或不拉绒布帘，只拉纱帘、遮光布。是什么意思？

The materials, summer use curtains of light transmittance is stronger in General, material should be treated with light permeability. Rongbuk in European style with good performance, but using too heavy in the summer, owners can choose to replace or not napped fabric curtains, gauze curtains, shade cloth only.
