He maha ngā whakamahinga o ngā kōtaha PVC hei whakaputa i ngā hua whakaputa, e whakamahia whānuitia ana puta noa i ngā rāngai hanga, whakapaipai, ahumahi me te ahuwhenua. Ko tōna rongonui kei roto i te nui o te whai huatanga o te utu me te ngāwari ki te urutau ki ngā āhuatanga maha, engari ko te pumau o te mahi me te roa o te mahi e whakawhirinaki ana ki ngā wāhanga matua pēnei i ngā mea whakau.Ngā whakaū TopJoyHe mahi nui tā ngā kōtaha PVC ki te whakatika i ngā herenga ā-roto o ngā kōtaha hei whakatutuki i ngā tono maha.
Ka whakarōpūtia ngā kōtaha PVC mā te tono kia aro ki ngā hiahia motuhake. Ko ngā momo matua ko ngā kōtaha tatau me ngā matapihi o te whare (te matua mō te whare hanga whare), ngā kōtaha whakapaipai (ngā papa whāriki, ngā rārangi whakapaipai mō te whakaotinga o roto), ngā kōtaha ahumahi (ngā whakangungu taputapu hei tiaki) me ngā kōtaha ahuwhenua (ngā anga whare kati kōtuhi mō te whakatipu hua).
He nui ngā painga o ēnei kōtaha: he kaha te ātete ki te waikura, he māmā mō te tāutanga ngāwari, he tino pai te whakapaipai (he rite ki ngā kakano rakau/kōhatu) me te pumau o ngā āhuatanga. Heoi, he uaua te tono ki ngā herenga ā-roto—he ngoikore te ātete ki te pāmahana teitei (he ngawari ake i te 60°C), he pakarukaru ki te pāmahana iti (he ngatata i raro i te -10°C) me te ngawari ki te koroheketanga o waho, e aukati ana i te whakamahinga i roto i ngā taiao uaua.
He rerekē ngā āhuatanga tono, ā, he whakaritenga mahi kua whakaritea. Hei tauira, me ātete ngā kōtaha tatau me ngā matapihi o te whare ki te tawhito o waho me ngā rerekētanga o te pāmahana, engari me ātete ngā kōtaha ahumahi ki te wera kia urutau ai ki ngā taiao mahi taputapu. Nā ēnei tono ka puta he hiahia nui mō ngā otinga whakaū pono.
Ka whakaratohia e ngā pūmau TopJoy he otinga kua whakaritea mō ēnei āhuatanga mamae. Ka whakarei ake i te ātete pāmahana teitei/iti o ngā kōtaha PVC, ka ārai i te koroheketanga o waho, ka pupuri i te pumau o ngā āhuatanga, ka roa ake te ora o te ratonga. Mō ngā kaihanga, ka āwhina ngā otinga pono a TopJoy ki te whakaputa i ngā kōtaha kounga teitei e tutuki ana i ngā whakaritenga motuhake o te rāngai, ka whakanui ake i te whakataetae me te whakawhirinaki o te mākete.
