Holes & Notches
To accommodate service voids and column notches, the hollowcore can be pre-formed
to individual requirements. Large openings may require steel trimming supports. It is recommended that holes of less than 100mm diameter are drilled on site, on the centerline of cores.
A number of ceiling finishing options are suitable for hollowcore units: Soffits can be plastered using a suitable bonding agent. Proprietary suspended ceiling systems can be hung from supports located between units. Counter battens can be screw fixed to the soffit for a plaster board finish.
