Need to build a box on the ceiling in the kitchen.
300 high, 700 deep and 3300 long.
Two duct fans at 25 kg each are to be hung underneath.
8 halogen/LED lights will be mounted.
What boards are best to use?
Thinking of 12mm chipboard and 45*45 studs as the frame.
Glue and screws.
The box will be placed 3.7 m high. The ducts for the fans will lie in this.
Is this the right approach?
Or must plywood plus gypsum be used?
