Rockwool/fiberglass is out of place in your car!

I heard that many people use fiberglass for car insulation. What sort of material it is? Is this material appropriate for car insulation? I decided to go deep into these questions.

Fiberglass proved itís efficiency and is considered as one of the best insulators today. It is pretty cheap and popular among car enthusiasts. There are plenty advantages of this material. Mineral wool is used for thermal insulation of roofs, floors, walls and etc.

But there are some cons of using this material some people even donít know about.

Letís throw a light on them.

Fiberglass: myths and reality

Myth №1: fiberglass is the best thermal insulator.
This is partially true if you are talking about house interior. Rockwool will work if itís kept out of moisture,that means inside.Rockwool wonít work if it gets wet. Have you ever noticed condensation on your car metal surfaces like doors?If applied in your car rockwool starts to absorb moisture and destroy itís body.

Myth №2: fiberglass is a safe material

Rockwool consists of mineral fibers held together with resins based on formaldehyde.The better the quality of rockwool the more harmful resins it has.With time resigns start to decompose, mineral fibers turn into dust and penetrate into car interior holes. They are really harmful for human health as they penetrate into the lungs and become the cause of many health problems.

Myth№3: Mineral wool is fireproof
Rockwool can be referred to non-combustible materials but the resigns ,which are the part of glue mixture, are susceptible to burning.They can emit poisonous substances into the air and you even donít know about this.

Myth№4: Mineral wool is a cheap material to insulate your car

When applying mineral wool in the car you have to get a lot of material.In order to apply mineral wool youíve got to use the whole sheet.You cannot cut it in pieces and apply them separately. Consequently, you will have a lot of leftovers after the application.

So what is the best alternative for mineral wool?
There are a lot of car insulation materials that are harmless and easy to use. And,what is most important
that they are adapted to changeable car environment which is constantly heated or cooled and can be humid as well.

The materials that also can be used instead of rockwool:
1) A foam that absorbs moisture but doesnít evaporate it
2) Peno polyurethane that appears to be a bit more efficient in terms of vehicle deadening

What about making a list of mineral wool alternatives?
What can be applied in a car in order to insulate it and not to cause decomposition?
