Insulation/ sound deadening

Post by Benny88 » Sun Jun 13, 2021 9:39 pm

Folks I need some help!!

Iv recently brought a new van and have started to strip it down ready so can get my racking sorted for work. Upon taking off the ply lining already fitted, I saw that it’s had some insulation applied but no sound deadening

Does anyone know if either I can

1 strip it all off so I can start again


2 if I can apply the sound proofing over the insulation (but to me I think it would be pointless as it isn’t on plain metal)

Cheers in advance

You’d be best stripping it off. The sound deadening is designed to stop the metal resonating.
Make sure you wipe the panels first with alcohol wipes or similar. Also, silent coat doesn’t stick on the roof for very long, so I wouldn’t bother doing it. Other brands may stick better, I’d do research into this first.

As above strip it all off and start again, unless you know the insulation type bin it asit may absorb moisture and then you rot the van out from he inside.

Sound deading wise, its all about adding ,mass to a panel, the often foil backed sound deading does this but only for lower frequency, you idealy need to then add another foam layer for higher frequency then insulation on top.

Is the insulation not waterproof, have put some in my doors, and was wondering if we soak up water.
