insulation i mean protection/rejection of extreme heat outside (also sound)....summer here reach bout 40 deg. Celsius..so AC is workin overtime...yeah Dynamat is one of them...too expensive though thats why im thinking of an alternative way..what you think?

I reinforced my carpet with a layer of carpet padding. I also used padding to pad out/fill my door inserts. That worked great, but it was more of a sound deadener than weather insulation.

I did consider a way to use insulation... I tried a bit of the expanding foam and the bagged foam.
I drove around testing it and didn't see a difference, plus the foam and insualtion was just too ghetto, even for my dumb ass.

E-dead or fatmat is pretty cheap and can go a long way.

In this question, "Dynamat" refers to all commercial products that are marketed expressly for reducing ambient noise in the car. Dynamat, Stinger RoadKill, et al. all have similar pricing, so this question is intended to give non-standard options.

There is a material known as "Ice Guard," which is used by roofing contractors. It is similar to Dynamat, both in thickness and density. It is self-adhesive on one side, and seems to work very well. Unfortunately, it is sold only in large quantities (225 ft^2 rolls), and runs about $70 for this much. Perhaps a few people could get together for a roll, or it might be possible to get scraps from a roofing contractor.

Heat is going to come through your windsheild and windows anyway, insulation is going to keep it in more than anything I would think. Would obviously work for sound though...

Grace Ice & Water guard is asphalt. It will do nothing to reject heat and very little to reject noise. It is not meant to be used in high temperatures, so it will probably melt. It really isn't comparable to Dynamat at all. Dynamat uses a butyl adhesive that is much more resistant to heat and has a heavy foil lining that both protects the adhesive and improves its insulating abilities. It's also more than twice as thick as Ice & Water Shield.

Best thing to do is get a liquid paint on product like Second Skin Firewall, Lizard Skin Ceramic or the similar one made by Cascade. Of these three, the Second Skin product is a good compromise between heat and sound proofing. Lay it on about 2mm thick and you should notice an improvement. Need a good heat rejecting tint for the windows too.

i have some excess rolls for duct insulation, its a sort of a fiber glass material sandwich with aluminum foil with diff thickness...you think this will do?

Might help with the heat, not too much with noise since it isn't heavy enough to damp vibrations effectively - should absorb some high frequency noise. Just make sure it isn't harmed by moisture if you are going to put it inside your doors.

ic..well i have to check the manufacturer for moisture reations on this insulation..
though im not to particular on the acoustic but the only thing that bothers me is the hssssssssss noise which i think is caused by the uneven slits on the body and some damage rubber gasket on the winshield and doors...(maybe im wrong)

Sounds like damaged weather stripping. Only thing that will solve that problem is to repair or replace it.

They are the rubber parts. There should be one going around the door frame (the car, not the door). There will be one where the windows go into the doors. One goes around the windshield. Any place you see rubber filling the gap between two metal structures.
