Indwangu engalukiwe ye-spunlace efanelekela izembozo zezimoto ezivikela ilanga yenziwe kakhulu nge-fiber ye-polyester engu-100% (PET) noma i-fiber ye-polypropylene engu-100% (PP), futhi imbozwe ngefilimu ye-PE engamelani ne-UV. Isisindo ngokuvamile siphakathi kuka-80 no-200g/㎡. Lolu hlu lwesisindo lungalinganisela amandla okuvikela nokukhanya, luhlangabezane nezidingo zokuvikela ilanga, ukumelana nokuguguleka kanye nokugcinwa okulula.
