How much is needed? Sound deadening

[Daggz68]

I see this on amazon, but not sure how much would be needed to do the sides, rear doors, roof and floor? I'll do the front doors and floor later on.

I used nearly 5 SQM to do the front foot wells, front doors (partial) and full bulkhead.. not done the rear, but it's a fair amount you will need

You want the whole sides, so upper and lower panels, roof, doors and floor done?

I've ordered a 40 sheet (3,7sqm) Dodomat pack and that's not enough. Guess you need about 5 sqm or so.
Also depends if you put in the effort to cover every panel.

I used 2 boxes for my caddy maxi. Not including the front cabin which I'm yet to do.

Hi. Just bought a 2018 caddy, after reading the comments assume I need 50 sheets as just doing the back. What size and thickness roll of deadening would I need, and also the insulation I would need. Any advise much appreciated.

judging by how much I used for the cab and bulkhead, for significant coverage I'd 'guess' about 20m square for a Maxi.
I'm sure others will comment who have done the rear. Also, if some of the guides show specific areas rather than full coverage, I guess will be less.

Based on listed dimensions of a Maxi.. full coverage...
Rear door area 1.2m X 1.2m = 1.5m sq
sides, 2.2 X 1.2 (X2) = 2.6m(x2) = 5.2 m sq
roof and floor, 2.2 X 1.2 (x2) .......= 5.2m sq
bulkhead = 1.5m sq...

front cab.. 3 to 5m sq.. from experience..

= 16 -20 m square... plus curves and wastage..

So regarding that pack from amazon, how many to do the rear. May as well put maxi so I'll have some left over. Brain is fried so won't try and do maths this eve

dodo Matt is available most cheaply as a 5m Square roll... not sure on size and area of the packs of individual sheets
