Necromancing this thread, been pulling apart the front carpeting. Looking on Google for some info on Volvo 240 Sound Deadening and this thread came up top.
There's a couple of sound deadening floormats under the driver and passenger floor (1313119 LH & 1313120 RH) made from Mass Loaded Vinyl (MLV) although it looks as if the "vinyl" my be some sort of vulcanised rubber.
Mine were stuffed, a bit of moisture some surface cracking but most of all "The Smell".
Driver's side was starting to crack and looks like some water ingress. White powder is zinc from the galvanized wiring & hose service cover. Also looks like some sort of exotic Swedish mould.
Anyhoo Car Builder makes a "Mass Noise Liner" the weight and thickness looks the same. 10mm foam and approximately 3-4mm vinyl.
Got a sheet from Autobarn and can just fit in the front mats and have enough left over for the firewall insulation. Best way I suppose is to keep the pattern that slots into the floorpan…….. any sacrificed mm to be at the top. I've got these laid out roughly and should have the floorpan side in the middle.
Does anyone have a engine firewall insulation pad that I can get a pattern from?
