Is this a one piece sized at 60x40"?

Yes. It comes as one piece. Make sure you don't plan on using it for voice isolation though. Works great for thermal insulation

How many of these should i order for an extra cab silverado. Want to do doors, floors, back wall.

You will have to measure your interior. I would assume it would take four. If you are trying to quiet your vehicle then you want a butyl sound deadening mat (at least 50 mil) and cover about 25% using smaller squares located strategically to keep body panels from vibrating. It is kind of heavy like peel and stick roofing material. Then insulate.

What the heck is "high density foam cotton" ??? is it cotton or is it foam? it cannot be both.

It would appear to be a poor language translation. The term "cotton" probably is meant to be a description for a flat layer of foam insulation as one would use a cotton blanket.

It's OK, perhaps a little too thick, it's not very strong either and if you apply it and want to move it, nope. It just tears off. So it's what it costs sort of thing. I'd recommend a thinner more expensive version of this.

Utilisé pour refaire l'insonorisation de la tôle entre moteur et habitacle,côté moteur, d'une clio. Posé il y a quelques mois, le collage n'a pas bougé et l'effet insonorisant est réel. De plus, cet isolant n'a pas l'air d'intéresser les rongeurs qui avaient déchiqueté celui d'origine (genre de laine minérale compressée) sur ce véhicule qui dort dehors en campagne.

I bought this to replace the foam under the engine cover, it's really sticky and did a great job. Also used to sound proof in the boot so a great product.

Bel isolant, ne semble pas intéresser les rongeurs, contrairement à la mousse d'origine de mon Ford Ranger. La face métallisée offre un bonne protection Se mets en place sans problème, tient bien en place.
