Asbestos cement tween panels (Fillets) and beam insulation for fire rated flooring/ceilings in multi-level structures
Description
Fillets were constructed from recommended low density board (LDB) or AC sheeting.
Fillets were designed to be screwed/glued to joists between the ceiling tiles or AC sheeting to achieve fire rating.
Identical use as in single storey but with added layers of fillets to allow insertion of insulation around beams in tween flooring space. Beam insulation covered with AC or LDB sheeting.
LDB sheeting/strips needs particular care due to low density of product matrix that tears and damages easily.
