These asphalt products are used instead of CLD, which reduces vibration. Just another note - the asphalt lining products are not exactly a substitute for a soundproofing layer, that's what MLV is for. Not sure how much it will help, but it's cheap as chips and I need the thermal insulation anyway. Personally I gave up on the idea of using MLV (mass-loaded vinyl) and will just use a combination thermal/acoustic insulation product, probably polyester batts. But there's still a problem of the asphalt running.īut if it's turned out to do the job well and lasted at least this long, I'd still be interested to know! So I suppose depending on how it was used in a Sprinter fit out it may not fall away. If you look at the Grace info it shows their products adhered to a completely flat surface (so 100% adhesion) and then held in place with the actual roof directly on top. Plenty of people have posted about having the asphalt products fall down after a bit of a hot day (not just here but on plenty of other forums as well). I'll bet that anyone who uses it will end up with a goopy mess if they try and remove the lining or need to remove panels that are covering it. The asphalt will stink, and it melts in extreme heat. never knew that info about asphalt-based products!įrom what i've learnt about using those roofing materials for soundproofing - basically you get what you pay for. A search can be conducted using the product name, UPC codes etc. Per State and Federal OSHA requirements manufacturers must readily provide MSDS of their products.Īnyone considering using any insulation, adhesive, chemical or building material in their Sprinter buildout is highly advised to conduct a Google search on the product's MSDS to verify if exposure could or will lead to health hazards etc as well as the proper safeguards to undertake when using such products.įor example 3M has made a worldwide (per country and language) MSDS search available online for downloading at : MSDS formats can vary from source to source within a country depending on national requirements." It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. "material safety data sheet (MSDS), safety data sheet (SDS), or product safety data sheet (PSDS) is an important component of product stewardship and occupational safety and health. Still a little intimidated to go tearing into dash and doors but after putting the rubber up and eliminating noise from the rear it accentuates the motor noise I get.įYI for those who do not know MSDS stands for Material Safety Data Sheet. Started putting Raam stuff in passenger area. I'm going to apply this to the inside of my panels before I screw them on to form a seal between panels and metal, which should serve as both vapor barrier, eliminate panel rattle, and give more sound deadening. I doubled up the big window panels just to finish up the roll and tapping them from the outside sounds solid. The sound inside is completely deadened, and driving is amazingly better. (I used a flexible putty knife to get where the roller couldn't) then it's stuck for good. It can be easily pulled back to reposition until it's rolled or pressed down. Results were much better than I expected. Air bubbles are your enemy with stuff, so I applied it carefully, rolled it (critical in making it stick) and the bubbles I did get I carefully sliced open then rolled. I didn't really trust the self adhesive back so gave it a little help with spray contact adhesive applied only to van, let dry to tack and apply rubber. I wanted to do some soundproofing in cargo bay without spending a fortune so settled on rubber roofing from Lowes.
