roof lining

[blue ute]

Apart from dynamat what other options are there for lining the inside roof, the old bitumised cardboard on mine has seen better days.

Carpet underlay or a lino style underlay could both be glued on, needs to be glued well though or you'll end up with a lumpy hoodlining if it drops.
If the original stuff is still structurally OK I'll glue it back up.

Stinky I did think of carpet underlay but the stuff I've looked at is too thick to fit between the hoodlining bows & roof.
Incedently what was the purpose of the insulation, is to reduce inside cabin heat or noise or both or neither.

[stinky]

Both, probably more to do with noise though as a panel as large as a roof would tend to "drum" whilst driving. You can get different thicknesses of the carpet underlay, I think there is a 6mm version that should do the job.

Stinky it's on a ute so wouldn't think there would be any drumming, nor much heat for that matter, unless it's keeping the bows off the roof to stop them vibrating ??

[stinky]

Do you want to wait until your car's on the road to find out if the ute roof drums or not?

As has already been suggested it probably serves a combination of purposes.

To stop the roof metal drumming (more so a problem in sedans and wagons than utes because of the roof area ).

Some heat insulation.

And to assist in stopping hood bows from touching the roof and causing an annoying vibration which would drive you mad on a long haul.

I'm currently looking at the same thing.

I also found car stereo insulation carpet, may be another alternative. It's used to go around those external speaker boom boxes, and can be glued to the roof also.

I believed it was for both heat and sound insulation.

I used Dynamat, thin and sticks like sh*t to a blanket!
