Hiri ahi me te paowa pakari kua whakatauria ki te ahi mō te tatau
Ko te hiri o te Gallford Intumescent Fire Door he mea hanga ki te karāhe kua tangohia te kiri, ka whakamahia mō ngā tatau ahi me ngā matapihi, mō ngā wāhi katoa rānei hei ārai i te ahi, te paoa me te oro. Mā te whiwhi i te kounga me te reiti whakamarumaru e hiahiatia ana, ka mau tonu tō oranga haumaru.
