Nsalu zoteteza dzuwa zimapangidwa ndi ulusi wa poliyesitala ndi PVC, zomwe zimagwiritsidwa ntchito kwambiri poletsa zinthu zovulaza za kuwala kwa dzuwa ndi kuwala kwa ultraviolet, ndipo zimagwira ntchito bwino pamunda wothirira dzuwa.Ndilo yankho losunthika kwa onse omwe akufuna kusangalala panja popanda kuyika pachiwopsezo chambiri komanso kutentha kwa dzuwa.Nsalu yatsopano, yopumira imalola kutentha kuthawa ndikuziziritsa malo, kuchepetsa kutentha mpaka madigiri 15.

Nsalu zotchingira dzuwa zimagwiritsidwa ntchito kwambiri ngati chotsekera chamkati cham'nyumba cha sunshade, makhungu oyima, mitundu yonse yamitundu yotchinga, mithunzi yachiroma, zokongoletsera ndi magawo.

Nsalu zoteteza dzuwa, yomwe imadziwikanso kuti nsalu yoteteza dzuwa kapena yoteteza ku dzuwa, ndi nsalu yopangidwa makamaka kuti iteteze ku zotsatira zovulaza za cheza cha ultraviolet (UV).Amagwiritsidwa ntchito kwambiri popanga zovala, zida, ndi zida zakunja, monga zipewa, malaya, zovala zosambira, ndi maambulera.

Nsalu zoteteza dzuwaamapangidwa pogwiritsa ntchito ukadaulo wapamwamba wa nsalu womwe umaphatikizira zinthu zotsekereza UV mwachindunji munsalu.Zinthuzi zimatheka kudzera m'njira zosiyanasiyana, kuphatikiza kuwonjezera kwa ma UV-absorbing agents panthawi yopanga kapena kugwiritsa ntchito ulusi wolukidwa bwino womwe umatchinga mwachilengedwe.Ma radiation a UV.Nsaluyo nthawi zambiri imavotera kutengera ultraviolet protection factor (UPF), yomwe imasonyeza mlingo wa chitetezo cha dzuwa chomwe chimapereka.

Cholinga chachikulu cha nsalu yotchinga ndi dzuwa ndi kuteteza wovalayo ku zotsatira zovulaza za kuwala kwa UV, zomwe zingayambitse kutentha kwa dzuwa, kukalamba msanga, ndi chiopsezo chowonjezeka cha khansa yapakhungu.Povala zovala zopangidwa kuchokera kunsalu iyi, anthu amatha kusangalala ndi zochitika zapanja pomwe akuchepetsa kukhudzidwa kwawo ndi cheza cha UV.

Nsalu zoteteza dzuwa zimapereka maubwino angapo pa nsalu zokhazikika pankhani yachitetezo cha dzuwa.Amapereka mlingo wapamwamba wa UPF poyerekeza ndi zovala wamba, mogwira kutsekereza gawo lalikulu la cheza cha UV.Kuphatikiza apo, nsaluyo ndi yopumira, yopepuka, komanso yomasuka kuvala, ndikupangitsa kuti ikhale yoyenera kuchita zinthu zakunja kwa nthawi yayitali.Mitundu ina ya nsalu yowala ndi dzuwa imapangidwanso kuti ichotse chinyezi ndikuwuma mwachangu, kupangitsa kuti ikhale yabwino.
