He porowhita te hoahoa o te mowhiti o waho o te peera UCP e hono ana ki te mata kōpiko o te whare peera. Mā tēnei hanganga ka taea te whakatikatika i te hē o te tuaka i roto i te whānuitanga o te 0.5° ki te 2°, ā, ka taea te whakauru i ngā āhuatanga tāutanga. Mā te hanganga whakauru ka māmā ake te tukanga huihuinga, ā, ka taea te whakakapi takitahi i ngā wāhanga peera i te wā tiaki, ā, ka whakaitihia te wā tiaki me ngā utu e pā ana. Mā te hiri whakapā taha-rua ka ārai i te urunga o te puehu, ka pai ai te peera mō te whakamahi i roto i ngā taiao puehu. Hei tāpiri, ka taea e te peera UCP te mahi pono i raro i ngā pāmahana mai i te -30°C ki te 120°C, e whakarite ana i tōna whakamahinga i roto i ngā tono tere me te taumaha.
