I couldnt find information about whether the cab is insulated or not.
I found some videos about insulating and sound deadening the cabs of trucks and I thought that might be interesting.
Does somebody here have experience with insulating the F150s or with replacing the carpet?
Thanks in advance for every information!

 

Just remember that stuff all adds weight that will take away from your payload.
The carpet should have padding under it for heat/sound insulation. There is/may be a small pad on the outside/back of the cab but I think that is about it. Nothing in the doors/ceiling that I have come across, or not much and just a little in the pillars I remember seeing in the video about the seat belt pre-tensioner recall.

 

Thank you for your input. Indeed it is a little more weight. But for long traveling I think it makes sense for me personally. First I will only insulate the doors because they are easier to do. I added two pictures of how it looks behind the door panel. In the rear door is no insulation except this thin PE foil, the small piece of fleece, and one patch in the middle of the outer door sheet.

Rear passenger door. Door panel off

 

I think it depends on your trim level.
Upper levels should have more sound deadening.

 

I thought about that too. A Platinum should look different. Mine is a 2015 XLT 302a

 

If you want to add sound deadening insulation, the floor and the fire wall are the biggest sources of noise. Doors are minimal, which is why Ford spends very little money insulating them. Obviously adding a little here or there won't cost you much, but on Fords scale they probably determined the benefits weren't worth the cost.

The floor and the fire wall should have insulation.

That sticky mat inside the door is insulation. For example, look up the product FatMat, which is essentially the same thing.

 

I first added this aluminum/bitumen inside the backdoors. On the front doors I furthermore added audio insulation.

 

On your truck, behind the glovebox up from the footwell, is there a sound panel?

Mine has one, if your doesn't, maybe you can get one from a parts dealer.

 

the small panel in the door, is all that is needed. adding more results in diminishing return. a lot of work for little return unless your about sound systems.

the back panel is biggest contributor followed by transmission tunnel exhaust and then the seams where the door closes.and kick panels behind the front fenders

these by and large do more for you than covering the entire floor

a better swifter and more precise means to this end is to blanket the engine. oil pan first. valve covers exhaust manifold ( s)

you will gain greatly by tracing the contributive noise back to its source which is , of course, the engine.
seal that up and save effort , time and money
