How do you fire upgrade a lath & plaster ceiling?

Underdraw the existing lath and plaster with chicken wire (supplied by others and fixed in accordance with manufacturer recommendations). A cavity should then be formed by counter battening with minimum 38 x 38mm timber or by using GypLyner UNIVERSAL. Various Gyproc plasterboards can then be screw fixed to the underside of the battens depending on the fire performance required. Please refer to WHITE BOOK Chapter 06 Section 06 Page 04 and Page 13 for more details.
