He rite ngā wira ki ngā "hū" o ngā taonga whare, o ngā taputapu rānei, nō reira mā te whiriwhiri i te rauemi tika ka māmā ake te neke me te tiaki i te whenua. Kei raro nei, ka tangohia e mātou he 3 meneti hei whakaako i a koe me pēhea te wehewehe i ngā painga me ngā ngoikoretanga o ngā rauemi matua e toru, arā, te nairona, te polyurethane, me te rapa, hei whakarato i ngā whakaaro hoko e ahu mai ana i te whenua.
1. Tirohanga Whānui o ngā Rauemi
1). Nairona (PA)
• Ngā Kupumatua: Mārō, Taumaha, Haruru
• Ngā Āhuatanga: He pakari rawa, he kaha ki te pikau i ngā kawenga, engari he haruru nui te hurihuri; he ātete ki te kakahu engari kāore i te "ngawari". I muri i te pana me te tō mō te wā roa, ka rakuraku pea ngā papa rakau, ngā mata uku rānei.
• He kupu whakarite tirohanga: Pērā i ngā potae o te waka haereere, ka taea e ia te kawe i ngā kawenga taumaha engari ka haruru nui.
2). Polyurethane (PU)
• Ngā Kupumatua: Ngāwari, Mārie, Whānui te Mahi
• Ngā Āhuatanga: He ngāwari i waenga i te kirihou me te rapa, he iti te haruru, he ātete ki te hinu me te waikura. He pai mō ngā awheawhe kore puehu, ngā taiwhanga, ngā hōhipera, me ētahi atu taiao he tino uaua ngā whakaritenga; he pai mō te papa, kāore he tohu pango e waiho ana.
• He kupu whakarite tirohanga: Pērā i te takahanga waenga o te hū, he pumau, he marino hoki.
3). Rāpa (NR/SBR)
• Ngā Kupumatua: Ngāwari, Pūmau, Utu iti
• Ngā Āhuatanga: Ārai-paheke me te pupuri kaha, kāore e paheke ina panaia ngā kawenga taumaha; he mimiti ru kua whakauruhia, he marino, he ohanga hoki. Ko ētahi o ngā ngoikoretanga ko te koroheketanga i raro i te roanga o te rā me te rerekētanga i raro i ngā kawenga taumaha.
• He kupu whakarite tirohanga: Pērā i ngā potae marino o tētahi motuka whānau, me pana "mārie" kia kore ai e utaina te taumaha mō te wā roa.
2. Kia Mārama ki te Kōwhiri me te Tēpu Kotahi
| Ngā Hiahiatanga o te Horopaki | Rauemi i Manakohia | Take |
| Ngā kawenga wheketere taumaha, ngā papa sima | Nailoni | He kaha te pikaunga, he ātete ki ngā karawarawa o te papa |
| Ngā hōhipera, ngā taiwhanga, ngā ara hōtēra | Polyurethane | Āta marino + tiaki papa + ātete waikura |
| Ngā kāpata rokiroki kāinga, ngā kāpata pana tari | rapa | He marino, he ārai-paheke, kāore e kino ngā papa rakau, he iti te utu |
| te pānga o te rā me te ua ki waho | Polyurethane (ātete UV kua whakarerekētia) | Ātete ki te koroheketanga, ka ngawari te pakaru o te rapa i raro i te rā |
| Me whakanoho te pēki | Ahakoa he aha ngā rauemi, arotahi ki te hanganga parai | He mea nui ake te roa o te oranga o te papa pēki i te rauemi o te mata o te wira |
3. Ngā Whakamātautau Hokonga e Toru-Taumata
1. Tirohia te papa: Mō ngā papa rakau me ngā papa uku, ka taea e koe te whiriwhiri i te PU, i te rapa rānei; mō ngā papa sima, maitai rānei, he pai te nairona.
2. Whakarongo ki te taiao: Mō ngā tari me ngā hōhipera e hiahia ana kia "kore haruru", me karo i te nairona.
3. Paunatia te kawenga: Te kaha kawenga o te mīhini kotahi ≥ (te taumaha taputapu katoa ÷ 3), ka waiho he tawhā haumaru e ranea ana.
Whakarāpopototanga i roto i te rerenga kotahi
Ngā kawenga taumaha, kāore he āwangawanga haruru—kōwhiria te nairona; e hiahia ana ki te marino me te ma—kōwhiria te polyurethane; e hiahia ana ki te penapena moni engari kia marino—kōwhiria te rapa. Whakatauritea te rauemi ki te horopaki, ā, kāore e uaua te whiriwhiri i ngā wira.
