Installing Cellulose Insulation

[luvkountry]

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.

[senorjorgegonzales]

you can't rent insulation blower machines in the UK. What do you think of mixing the cellulose in a huge bucket with some water and then throwing it on the walls by hand? Perhaps similar to rendering/harling/plastering? Take a long time, but what are my alternatives?

[cotequadsport]

@senorjorgegonzales do not do that at all what so ever. you dont want this wet stuff in your wals anways. its a joke and takes forever to dry if it ever does. basiclly you have no alternations. fiberglass batts

[myjavelina]

I am hoping to wet spray cellulose insulation into my cathedral ceiling on a new house. I live/am building way off the grid and there is no one within a resonable distance who does this type of install. I was hoping to be able to rent a machine and just do this myself. Would I be able to just buy a nozzle specifically for wet spray, and use a basic rental blower such as those found at home depot or rental place or is there a special type of blower used too? Any tips?

[cavibird2005]

Isocyanate Foam is by far a better bet the cellulose. I say this as a installer.

[b0ssh0gg]

great video, i am doing this today for the first time

[coventry87]

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

[kyleseevers]

@coventry87 if you are starting up your own company i would say yes go

buy one they are great i am a full time insulator and soon to own my dads

insulaton company, if you are looking for a quick one blowing job then

there would be no point they are very expensive,

[veggiepowered]

please come insulate my attic

[cotequadsport]

i do this for a living,(dense pack) we use a fiber material that is applied to the 2x walls then a hole is cut and a 2 inch hose is used to get up and down each bay.. when the walls are completeled, we then cover the walls with poly( plastic) which is used as a vapor barrier. why would you add water jusrt so it will stick. 1, the water will not completely evaporate(same theory as throwing a wet wash cloth in a ball)2, once (and if) it dries it will not be dense packed, it will settle..

[sammysf415]

what the machine used to suck up the left over insulation

[jjmaker]

Cellulose is an absolutely horrible insulator. Great sound deadener. I'd rather fiberglas bats than cellulose. Outdated product

[cotequadsport]

that is preposterous, you say cellulose isnt a good insulator? think of this, ever tear into a wall of an old house? well if you hvant, the cmost common insulator was news paper.. in case you dont know, cellulose is 93% neswpaper and 7% borax.. now fiber glass which is well, made up of glass. now when it gets cold outside touch a window. cold aint it? it is because fiberglass is a horrible insulator.. not to mention cellulose with fill a bay without air leaks, fiberglass can not compete pal

[jjmaker]

I'm sorry your knowledge of insulation is so limited, I'll try to update you. Sprayed cellulose in a wall cavity is a terrible insulator with an effective R value around 7. Fiberglas is a much better R product. Blown cellulose in attics does have similar R values as fiberglas. If you need any more help w/ product knowledge just let me know

[lancemanm1c0]

jjmaker.... maybe do some research on R values per inch.... cellulose is BETTER than fibreglass. Plus it is not thermally conductive... fibreglass IS. Fibreglass insul. relies on trapped air for insulation, whereas cellulose doesn't. It's more fire-proof, better at insulating per inch, and better at sound deadening. win, win, win.

[smazz104]

did you add any water or gluetype material to the cellulose mixture? I read that some people do this to allow the cellulose to "stick" to its application better.

Thanks

[rolficus]

im getting my roof done with this but theyre also adding wool to it will this make a difference and do they spray right into the roofs edge (the eeves)

[JonnyRawket]

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.

[econnelly27]

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

[JonnyRawket]

I'm referring to the caption at 0:44.

It's an oversimplification of the sound blocking phenomenon.

[gworrel]

Try encasing your house in 6 inches of solid steel without air leaks and let us know how well the sound gets in. It will be quiet as a tomb. Small air leaks are the primary means of sound transmission in a home. Your comparison to steel makes no sense.

[JonnyRawket]

Actually you're wrong. Large air leaks are the primary means. Medium leaks are less so, and small leaks are the least.

I can use the Google button on my internet machine too.

[gworrel]

You are right. Large air leaks transmit more sound than medium air leaks which transmit more sound than small air leaks. Sounds reasonable to me.

[67tallcool]

@JonnyRawket I just installed wall bar cellulose in the walls of my house and with the doors and windows closed you cant hear a thing.

[rolficus]

@JonnyRawket 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 .

[pupplesan]

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

[pupplesan]

Ack! Premature submition. To finish the question: I made the mistake of using this stuff as garden mulch. It killed the plants and my hands.

Thanks!

[verucabilderberg]

If they start selling cellulose insulation as fertiliser or moisturiser, then you will have a case.

[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.

[econnelly27]

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.

[dsharpe40]

@pupplesan dry adhesive... glue activated by water, with insulation, like for example, air , fuel, in a combustable gas engine.. ?? make sence , ?

[attapattapie]

Icynene baby!!! no comparison

[GeorgiaPatriot41]

Your right. Icynene costs a least 3 times more! COST PROHIBITIVE....BABY!!!

[chaos131313]

cellulose is ok but mice love it and it grows mold real well

[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.
