.......but did your waterpump motor have a tendancy to get to hot as its covered in ? as that's my worry with this motor an I don't wanit to catch fire an thanks Ron for your input

Over heating might be a problem for your application. My water pump is only on for enough time to fill a kettle!

Perhaps still worth a punt for the time it would take to trial the idea.

Polystyrene should work fine, I expect weight wise there will be little difference between that and foam. You could also try EVA foam which is lightweight, waterproof and available in various thicknesses - https://www.amazon.co.uk/Thickness-Cosplay-Project-DIY（9-6-pieces/dp/B07D4D96WK

CHEERS Bob for that i'll have a look

Cooling holes may work Chris. You need to reduce vibration transmission and overall noise amplification rather than noise per se. Another cooling option is a PC fan pushing fresh air through the area. They are very quiet in operation.

How about putting some polystyrene sheet on the underside of the roof too, and anywhere around the hanger etc. that won't be seen. Every little helps
