To ipaq4444,

Best is insulate both.

And if 4 sets of piping with 1/2 insulation, cannot fit into 4 x 3 trunking, it will be squeezed and defeats the purpose of having thicker insulation in the first place.

Min 6 x 3 or 6 x 4 for better fitting.

so there is a 6 x 3 trunking in the market? all along i only know there is a 3x4 and the ugly 4x4
