Sound travels through many things. One could say that sound can't travel through steel because it is airtight. In fact, sound travels tremendously well through steel. So, your reasoning makes no sense.

I'm not sure I understand what you are talking about.

If I may, some ignorant questions:

1: Is water added by the blowing machine? If not what allows the material to 'stick' to the wall cavities and not simply fall out?

2: What is the fire retardant? I made the mistake once of buying a cube of this material

[econnelly27]

Water is in fact added by the blowing machine, however the material is not soaking wet when it is applied to the wall. It is more like a mist of water to activate the glue compound in the material to allow the material to stick in the wall cavaties. Other situations might be cathedral ceiling in that case you would need netting material to keep the insulation from falling out.

The water is added at the nozzle. There are two hoses the applicator has in his hand. The one right above the cellulose tube is the water.

The amount of pressure the insulation in blown in at is what allows the material not to fall out. This material is dense packed which also creates less air to penetrate through.

[econnelly27]

Fire resistant qualities are owed in large part to a unique, two-stage process of injecting both dry and liquid fire retardants to penetrate its fibers, resulting in an exceptional insulation that exceeds every fire safety standard, and can provide up to 50% better fire resistance than fiberglass. Cellulose insulation also greatly restricts the amount of oxygen available to support combustion.

Sturmgeist1819 maybe you should consider doing your research before making an idiot out of yourself.

where can i buy a a cellulose blower in the uk, anyone?

[emutiny]

id guess its the fact that your video says sound travels the same path as air which is an utterly false statement. I stopped the video at that point to comment how I lost all faith in your promotion but somebody already brought it to attention.

cellulose has amazing acoustic abillities. do some research

[Linsey Knerl]

Use google and look up homemade cellulose blower. You will find some decent applications using a higher-end leaf blower. I have seen this used successfully as long as you realize you can't get the same "packing density" without some patience and extra time. Approximately 25 lbs per 16'' on center 8' area. Hope that helps. (high-jacking wife's acct atm please no comments:)

Hotpaper APS, har benytter papirisolering i over 5 år nu og vi rigtig tilfredse med det, vi er placeret på fyn nær faaborg.

Cellulose is an ingredient in processed shredded cheese. And it's NOT safe to digest. But they put it in food.

I'm building a house in the bush, and I want to wet spray my walls. The Cellulose Mfg Institute does not recommend a DO IT Yourself Installation, but it looks pretty easy to me. As long as you get the moisture content correct, how hard can it be. Do you know where I might be able to rent or buy the appropriate spray system to wet spray?

How will moisture evaporate if it is airtight/

Moisture produces mold.....

[cotedoug1988]

maybe down south this method would work nice.. not in new england. the moisture would never dry..

[773cat]

I prefer foam but it's to expensive. I have exposed framing like in the video, what netting do you recommend I use? You help is greatly appreciated.

cellulose acts as a buffer sound travels through air -and by creating many air pockets it traps the sound by dampening its effects and abilities to vibrate they bounce within the trapped pockets of air - steel is more dense and allows for sound to vibrate through its core due to the lack of air pockets , creating many airpockets is the same as the muffler on your car or the supressor on a gun each time the sound vibrates through each barrier it gets weaker .
