How to Install Spray Foam Insulation DIY 

Thank you with helping my decision

Great info!

Was it just roof you had sprayed ? Closed ornopen cell ? No condensation problem in winter ?

There must be some missing info here about the 2 houses. A typical attic is uninsulated. The home's insulation is found in the attic floor not on the attic ceiling. So the heat in the attic is determined by how well it's vented to the outside. The insulation doesn't make a difference because it's only creating a temp barrier between the house living space and the attic.

I live in North Port Fl heat & humidity take your breath & to pay outrageous energy bills to cool my house is absurd. I have done enough home construction to know I can do this to my mobile home interior wallas. 1x3 studs with cheap insulation. This should be great for my home. How much is the question. Home is 36x24

Some people think I talk too much but that is where the details are usually.

@@HouseImprovements there's no way you talk too much. That is what sets your videos apart. Very detailed. Love them.

Randy H where you buy it? S?

@@joelreyes8478 princess auto and Canadian tire have it.

Roy Korn can you tell me what insulation kit this was or the one similar to the one you used please.

Where do you buy the insulation kit home depot?

What brand is this kit?

@@trayvonlovell9301 I bought the Froth-Pack 200 by dupont, there are larger tanks available as well (650, etc). Make sure you you pull the the trigger all the way at all times - learned this the hard way the second time and I did not watch this vid as a refresher....

Truthseeker how far do those kits go?

It's crap if you want to do any work in the future

@@DemnRaig80 I run conduit for wiring (mostly Cat5/6, so 1") first so re-wiring is easier. I don't really see much need to open up walls otherwise

Thank you very much for sharing that information It is vital to know!

works nicely!

Are the rim joist what sits on the foundation edge around the house??!

Lol

Thanks. You da real MVP.

Thanks

Thanks

You really a life saver 🤣

J Martin Are you saying you spent $9000 in Foam?

This is similar to what I'm planning with my own remodel. I'll just be doing one room at a time as it will be a live in remodel. And due to being a live in I can't afford to rip everything out all at once to spray and then recover. For me the costs of the kits would be will spent in comparison to living in a hotel due the entire time of the tear out, electrical prep, HVAC prep, plumbing prep, shooting the walls/floors/ceilings, and then covering it all back up.

@Dale e Sounds like you had an unusually bad experience. I was referring to a vapour barrier applied over the wood framing and insulation before adding your gypsum board to prevent humidity penetrating from the inside. Any moisture problems coming in from the exterior of the concrete requires a barrier on the exterior side as well as proper drainage. Did your spray foam break down? That's surprising--wonder if any other people had that happen?

I thought 2" of closed cell foam constituted an air barrier...

You sound knowledgeable. Could you use this on a ceiling with corrugated metal ceiling? Any recommendations for brands?

@@TheJnetnunez Can be used for corrugated metal roofs. That is a standard "upgrade" people do to shops/barns. Just realize that it's basically glue, and replacing any panel it's sprayed on (say in 20-30 years) is quite difficult. Can still be done though. Brand doesn't really matter, you just want to use closed cell (rather than open) for the layer that contacts the roof. Open cell will absorb moisture and can cause problems.

@@whitenite007 we did a shop addition and all you should really have to do is put the pink styrofoam insulation board up first then spray foam.

Good tips thanks

Acetone

You're welcome, George.

no this is not a good trend because as soon as we get enough global warming than we wont have to use as much heat to warm our houses GLOBAL WARMING FUCK YA! DUMB FUCK climate change is make believe its all about the money 99 % of scientist agree climate change is made up to initiate a world wide carbon tax to enslave global population

So many idiots still alive I guess Darwins rules of evolution are not working now or you probably believe the world was made in seven days LOL. All climate change means is the weather is changing and is getting more severe however the reason the numbers and facts don't lie unlike idiots like you, happy inbreeding :)

How do I get spray foam here in Zambia

Look up Global Solar Minimum that is real climate change. Always follow the money on all issues.

trees dirt Shannon is the man!

Thanks for clearing that up.

Haha, i just came to the comments to say the same thing

Nirky You're BOTH correct! By his application of multiple passes, he IS helping the TWO chemicals the needed curing time. When applied too heavily, the curing time is greatly increased and the foaming effect slightly decreased. Think of it like a good pot of soup - letting it simmer s-l-o-w-l-y helps the over-all results.

Actually, there is a limit to the depth of the lifts too, because it is an exothermic reaction, ie, creating heat as it cures, the insulating properties can trap the heat inside a thick layer causing it to overheat. It will be burnt, crispy with poor insulating value and can actually catch on fire. The minimum thickness to create a vapor barrier depends on the permeability of the specific product being used, whether it is open cell, closed cell, low density, medium density, etc... This website says that the lifts must be between 12 and 50mm in thickness, the minimum to ensure that there is a sufficient temperature for curing caused by the exothermic reaction, the maximum to prevent overheating. Page 12. cufca.ca/docs/CUFCA_SPF_GUIDE_2013_Final_Xerox_Press.pdf

What happens to the wood if you don't put vapor barrier? If insulation is done like this, I really recommend vapor barrier. There should be one hole layer foam, when you can left vapor barrier out.

Omg that is awesome!

Greatest comment in man kind 🤯🤯🤯

😂😂 Tata

🤣😂😅🤩

REHEHEHEHEHHEHEHEHE

I was wondering what will turn it back to liquid. Thx!

I'm surprised they don't tell you these things. I have a can of spray foam gun cleaner and you'd think they would have you use that to clean the tips out if it starts to clog.

Thanks! That’s good to know.

@@harleymeyerink3747 You won't buy new tips if they tell you how to fix it.

Yeah spray foam cleaner or you can get a can of spray release as well.

are you using the guitar sting to cut off the excess foam sticking above the stud's after it has cured?

Expanding foam is compatible with all materials except human skin - and the old 1960's polystyrene granules are not harmful to PVC cables apart from being an attractive irritant.Sep 28, 2010

Thanks for that info. Looking at doing this very soon. On my house as we rebuild it.

@@loushear4497 One thing to keep in mind tho... Houses are designed for a certain rate of air infiltration to assist in a healthy rate of fresh air exchange and humidity. When houses are 'excessively' air tight, an Energy Recovery Unit is often used to make up for the lack of fresh air. Also, if your house is heated by gas or oil fired appliances (boilers or furnaces), they also need a source of unrestricted fresh air.

@@burnerjack01 no gas anything. Do you think walls and ceiling would be a bit much? I'm new to this as you can see.

@@loushear4497 I really can't say. I would do it. Absolutely. Just saying you may be setting yourself for "Sick Building Syndrome" (as best as I can recall). It's stagnant air that's the issue. Mold can become a real issue for you depending on your locale and temps. With bldg management and HVAC designing, it's always a battle between energy efficiency and health and comfort. Just saying before you go all in, do some research and always keep in mind that there are a lot of good and a lot of "hungry" contractors out there. Be thorough in your research and understand the 'micro environment your creating. Don't mean to be alarming, it's just that a lot of people don't really understand the big picture and they really need to.

Thanks 👍

+Betty Olson LOL!

Betty Olson works great Bettty

I always keep my tip lubed just in case!

Go old school, just spit on the tip.

Funny that's what she said!

Excellent!

IMO ,I do not think so.

Foam does mold if exsposed to moisture...

We would spray block and concrete basements on the outside from foundation footings up to the top amd only the exposed foam would need to be sprayed with a UV protectant and a fire shield.

The Froth Paks are extremely fast curing.

I would have gave everything one coat first just in case you run out and end up w/a cavity w/ no foam at all. Too expensive for a DIY guy to buy another kit to finish. Maybe finish w/ can foam?

That's exactly what I'm thinking about doing...but I don't know anything. 😄can we or should we spray wood with it? Like ceiling in basement also?

you are welcome

depending on the kit you purchase they will list how to get the best mix with their products.

yeah it depends on the kit

@@HouseImprovements what is the kit brand name? Which store selling it? And how much?

Its a 200 kit, 200 board feet to square feet. I just dont know the conversion off hand

@@GemCityRCOutlaws A board foot is actually a measure of volume. By definition, a board foot is one square foot, one inch thick. The most common mistake made in calculating board footage is forgetting to multiply by the thickness. Example 1: A 4/4 board 8 inches wide and 8 feet long has 5.33 bd.ft.

yes that is a good use for this

Using these systems should work fine working overhead, i personally have never used one on rafters but can't see why they would not work. Cover yourself head to toe as it could get a little messy. If you have a lot to do a foam contractor would be cheaper in most cases.

HouseImprovements very cool. how much did one of those 2 tank kits cost?

I would imagine closed cell is fantastic. This is one reason why I'm doing spray foam vs bat insulation.

+Jeff M Ok there is one problem with your math. The tiger foam is 600 sq.ft. at 1" thick. So if you want 3" one kit only does 200Sq.ft So the math is this : 11234 -10800. = 434$. So if your labour is worth anything The pro is a better deal plus I believe a good pro is a better product as far as consistency . Also I have never had a DIY kit yield as good as they are supposed to.

That figure I gave was accounting for this. 3" of foam, covering roughly 1200 square feet of wall. I guess I should've included that detail. So, it is still the $3600. That also doesn't take out the studs, so this too will add another 6% of product for use.

It's not. You explained it very well. I couldn't have said it any better myself. Nicely done!

+Jeff M Ever see what happens when you spray the foam in the wrong conditions? Try spraying the foam when it's incredibly humid and hot, it won't cure properly - ever. Kits IMO should only be used if it's a small area, and the humidity and temperature can be controlled for the entire curing process. Professionals will usually be able to compensate for differences in climate when it comes to new construction, where as a DIY guy wont know the first thing about the off the shelf foam he just bought, and won't understand what will happen long-term.

+Jeff M Your math is not right. The 600 kit is 600 sq. ft. at one inch. If you do have 3750 square feet and are looking for 3" then it is actually 3" x 3750. This is now 11250 board foot divided by 600 per kit. 18 plus kits is what you need. 18 kits x $600 per is actually $10,800 just for materials. Trust me people I have been a professional applicator and estimator for nine plus years. For a small project these are great if proper prep and safety is performed. But anything larger then about 1200 bd. ft. and you can have it done professionally dollar for dollar with someone else having the hassle and liability. One other thought, these tanks weigh 60lbs each (can get old quick moving these around a site) and you need to make sure your area will allow you to dispose of them. Hope this helps. Thanks Jeff B.

Where’s the fun in that?

The way I saw it the wires were on the back sides of the studs and not drilled through at all.

It is used in new homes a lot actually. Maybe your builder is not comfortable with it?

Thanks for replying back.

If you are that worried about future wiring, I would run conduit if possible. Then you can use single conductors instead of romex.

If you use closed cell there is still a space. You have to add makeup air if the building envelop is that tight.

You have problems running wires behind any covering on walls, however you can make a nice straight hole in this stuff with an red hot ball bearing doped from the top down. This is how they run wires in Sip's homes. Heat cuts right into this stuff like butter. So you can fish wires with a red hot poker. Wile wire isn't always going to be where you need it anyway. But I'd plan ahead and run the wires before Sheetrock any walls even plan on what you might run a few years from now like Cat 5e or 6e or even fiber. They make an inexpensive home use plastic fiber you can terminate later if its in the walls for later use. also you can run Low voltage wires for lighting upgrades. Homes are moving more to Automation so new stuff comes out everyday. Just plan ahead. Hey If I told you in 1903 to run copper wires next to your gas lines for lights, you would not had to hire an electrician to come wire up your home a few years later. I think cat 5e and 6e as well as fiber will be around for a few years anyway. Wired home phones are all but going out of style, and cable TV coax is going out of style, only other thing is Power wires and speaker cable's and or Thermostats. I really do not think your going to change wires all that much anyway, and I'll bet you would have moved out of that house after about 10 years or so anyway. The money you can save from Spray Foam over fiberglass insulation is a lot in energy cost, he's giving bad advice. but thats my 2 cents on it.

good deal

Makes great bumper cars. Hardly any dents.

BRILLIANT!

It must be covered with a fire protection like drywall or something like that.

Smoke a cigarette while you are applying it and let us know

That's the downside, very flammable as is rigid foam board.

inflammable. Very easily set on fire. Not once it is cured.

The foam insulation in the Grenfell tower tragedy was rigid flat panels, pre-made in a factory and attached onsite. Tragically, the many contractors and people involved used the wrong products, installed the wrong way in the wrong places for the wrong purposes. Sad tragedy but Hopefully the investigation results it will lead to better regulations, better oversight, better testing to prevent this in the future. And Hopefully All the existing screwed up buildings that made similar mistakes will somehow get retrofitted (corrected) to avoid a similar tragedy.

*The flat panels comprised the outer facade frontage, behind them was a slab of insulation foam, this ignited and aided the fire progress. What needs to be said is many products have fire certificates yet fail during a fierce blaze if enough heat is applied to them. Foam is not made to fight fires but to conserve heat. Foam burns and end of story*.

@@pipersson9258 The foam used in that case was extruded polyethylene. Caution with foam is absolutely warranted, but what is critical is that the right product is used in the right application, which that was not. Closed-cell foam like that most commonly used for high insulation value in the US can be purchased in a fire-rated form as well. www.greenbuildingadvisor.com/article/building-errors-were-behind-grenfell-tragedy

Yep I agree. These kits are hard to use even for everyday handy person. I sprayed a little structure over my well. Very messy and hard to get depth wanted. Plus insects loved it and quickly moved in boring all kinds of holes/tunnels.
