Insulated Duct MVHR

[Dutch]

I am considering purchasing the VENT AXIA SENTINEL KINETIC PLUS B 
It has been suggested pre insulated ductwork is the way forward.

The unit has 4 spigot of 150mm

distribution box  size 150mm

 

All the pre insulated ductwork I can find is 160mm so it would need reducers into the Unit x4

2 x Distribution box

 

Then I would need about 6 metres of. Insulated duct

11 elbow, from the what I can see I would need connectors between the pipe and elbows,

so far this process is ridiculously expensive £500 are the any cheapest supplier, tried bpc, ventilation land, epic air

I just used normal ducting (a mix of rigid and semi-rigid) and fed it through insulated ducting of the next size up. Cheap but effective. (Example supplier link to illustrate)
