Spark Plugs. said:Are there any alternatives for Dynamat? It's too expensive!
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.
fortunately i work in a construction industry...Perhaps a few people could get together for a roll, or it might be possible to get scraps from a roofing contractor.
You should get some and try it out....let us know what you think of it...!mhi said:fortunately i work in a construction industry...
yeah..im gonna do that...its gettin hot down here so need to work in it fast...You should get some and try it out....let us know what you think of it...!
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?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.
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.mhi said: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?
Sounds like damaged weather stripping. Only thing that will solve that problem is to repair or replace it.mhi said: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)
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.mhi said:everybody is saying that i have a damage weather stripping but honestly...i dont know where are those weather stripping... can you tell me where are these parts located?
