Great video! It cannot be stressed enough - installation, installation, installation! Insulation is only as good as the installation- as with most processes in construction. The gaps at the rafters are not deficiencies in the insulation- rather the installation. This contractor obviously did not care and is an easy job to pick apart. Unfortunately when it comes to insulation people only seem to care about how little they can pay. There will always be someone who will do it for less, and you end up getting what you pay for in the end. Thanks Jordan!

I've been spraying 2lb Sprayfoam insulation for 8 years in Canada...works great and haven't had major issues. It looks to me like he tried to spray 4" at once or was spraying too hot....you shouldn't spray thicker than 2" per pass. spraying too thick will cause the foam to 'burn ' in the middle and will kill your density and R value
@raysmith27555 жыл бұрын
on a side note here.... that was 1/2 lb. foam not 2lb. you can apply 1/2 lb thicker as long as your not blowing back the material. you are however correct in saying that about the 2lb foam. and on another side note.... i did the spray foam for over 10 years in the states. and none of my jobs never looked that shitty. whoever did that job was not trained properly.

Just like other sealants it’s important to have the bond into the corner and on both the sheet and the stud. Really not sure why more crews aren’t two people.

TheEarthDoctor1 sigh you made one good point. Andthat was the other point the rest are blatant lies. First off all they do not keep offgasing when mixed properly and applied properly the finished result is chemically inert. Yes they are toxic in a fire but so is cellulose and fiberglass insulation (Rockwool is not toxic in a fire, only fire rates insulation) They are no more problematic during demolition than most other construction material including plywood. The dust of fully cured spray foam isn’t even harmful (Beyond regular construction dust, cement dust and rile is much worse for your health) You say you doubt you’ll see contractors recycling the bits. And your point is?!?!?! Do you think they recycle Fiberglas insulation? No. Rockwool? No. Cellulose? No. Expanded or extruded polystyrene? No. So what’s your point? What part of construction is recyclable? I install recycle roofing, and I I’m pretty sure only about 1 percent or less of construction companies do. Or do you think anything besides metal is typically recycled in a demolition? Lol and even then it’s really only like copper. I don’t know what fantasy world you live in. Btw I don’t even install foam insulation unless specifically asked by the client or by the architects plans, I recommend Rockwool it cellulose. But I just can’t stand blatant liars with an agenda. In regard to it getting in your water supply, that is a huge problem with ALL construction debris, and that is why federal fines for construction waste getting into the water supply are typically in the $100,000’s per incident. Of course those are not enforced strictly.

We went all through this in Canada in the '80s. After sealing the house up, you have to incorporate air to air heat exchangers in order to exchange all the air in the house depending on local code and circumstances. Do you have five dogs? More air changes. Under the sills we staple a "sill-plate gasket" before standing the wall up. But stick-frame should be used when you live near a sawmill. Otherwise, masonry is becoming the structural material for low rise buildings when it's thermal mass is captured inside the envelope. We have to leave the trees standing whenever possible.

This video shows half pound foam, all foam contractors will try to talk you into buying this because the job goes really fast, the 2 pound foam is going to cost more but a thin layer of that inside and out is the best sealer, vapor barrier and high R value and keeps the OSB from burning the house down from the built in E84 fire retardant.

A quality installer is paramount. The guy that can read the foam as it expands, sets and a few minutes later check to see if the material has destabilized. The cell structure is another tell tale sign of the quality of the install. The shrinking foam from the studs, the shallow areas, and the cup sprayed into the wall all indicate faults of the installer. Do your homework. Find a reputable company with licensed installers that are trained to use the very brand they are installing. Anyone who is worth their salt will be able to provide a much higher quality finished product than what is on display in this video.

I have been scientifically taught good spray foam acts as a vapor barrier. I know it is accepted widely in North American building to meet code and most certainly qualifies as a vapor barrier. If you deploy spray foam and then use the exterior foil membrane, you have in fact created two vapor barriers that can not breath between them. Whatever is sandwiched between the spray foam and the foil membrane will retain moisture that leads to mold and rot. Now you have a problem coming to your structure down the road. Dual vapor barriers is bad news in my experience. Most building inspectors in my area don't even know this. I have only met a handful over the years that have the education and experience to acknowledge this. That foil wrap would work proper with a loose fiber type insulation on the inside but even better: Breathable exterior sheathing over the OSB or plywood With loose batt insulation in the stud cavities Vapor barrier on the interior studs. I very rarely use spray foam insulation on any job. It has its place but under ideal building situations in new modern structures, there is no need to deploy spray foam insulation. The spray foam insulation in this KZbin video was NOT FLASH sprayed with a wet coat prior to adjusting to the deep spray passes. This video does indeed show very poor installation of spray foam. It is not acceptable to see spray foam break away from the structure to leave gaps. If it is doing so then it is done incorrectly. I hope this home does not make its inhabitants sick in the years to come.

Cement, gypsum, vapour barriers and waterproof creams have caused rot and mold problems when applied to old houses because they trap water in the masonry. Lime+ hemp if done correctly has excellent humidity/condensation buffering and is naturally mould resistant due to its high alkalinity. If you are using hempcrete for new build then it can be used to create a full thickness wall which provides not only insulation throughout the wall but also thermal mass.

If you like mold and rot: yes. Making a house airtight on the outside of the insulation is a really stupid idea. Even the holes in the insulation of the original house would be better because the moisture could evaporate over time. The sealing will keep it indefinitely between the frames.
@cargogh5 жыл бұрын
Sven, I keep thinking about the house as a glass jar that I hold to my mouth and exhale into. The moisture starts collecting. You are correct. Giving credit to my expectations of that foil wrap, there's no way the interior will match the seal of the exterior. A boiled pot of water without the exhaust hood on, the same with a shower, a window left open during a rain, plumbing or roof leaks, or daily living--the house is soon a mushroom without moisture exhausting mechanicals. If the electricity goes out, a generator fails, or any component of the air exchange system goes out, let the mold begin.

In my opinion too costly and time consuming. Best option is to buy the ZIP sheathing and use the ZIP tape.

First, the open cell that's in the walls is different than closed cell ,which would be the better choice when it comes to spray foam. Closed cell has added structure strength and superior R value but with added cost. 2nd, canned foam and two part spray foam are very different animals. So the broad brush of the video title is a little misleading. 3rd, any probably my biggest gripe, is that the foam contractor that did this job puts all other foam contractors in a poor light. Simple things like air sealing around truss heels and soffit blockers is easy but the extra time and labor to someone that is already lazy is a recipe for what happened here. ( a cup foamed over in the wall...wtf!) Foam is a very specialized trade, many many things need to be watched and taken into account. From substrate, material and ambient temps, proper pressure of the foam type being sprayed, humidity of both air and substrate etc etc. We are manufacturing polyurethane on site, so everything needs to be monitored in order to make perfectly mixed inert plastic. Remember this the next time you look for the lowest bidder.
@guytech73105 жыл бұрын
Yup. Strong reasons to avoid spray foam. Unless the Foam guy is really good, your end up with problems. The other issue is with closed cell if you need to repair work or remodeling work in the future. Good luck trying to snake a cable or fix a plumbing leak in a closed-cell spray foam. Open cell is a moisture-water problem. You might as well just stick a wet sponge in your walls. One plumbing leak or exterior water leak and your screwed. I am sure the repair contractors love when a homeowner has to spend 3 or 4 times for a repair because of spray foam.

Most new homes have continuous exterior insulation. Near the end of Jordan's video he show the home with 2" Rigid foam insulation.

I'm not sure how many polyiso jobs you've hired out but I've had to fix air leaks in every single job I've ever done. It's very difficult to get 100 percent sealing. It boils down to this, if the rework you're inevitably going to do is too extensive and your contractor is not improving his quality, you have to move on to another company. It really comes down to the guy on the gun. If he can't be bothered to do what is expected, he's losing his company my business. I've had to switch contractors and I must say, the norm in thirs area for spray jobs is not great quality for price.

Any tips for drywall removal from spray foam? Our house had the entire roof insulated with spray foam to save on energy costs several years before we bought it. As part of a chimney demo we are nearly finished completing, we needed to remove the drywall from the ceiling so that new drywall can be installed in the next month. The original vapor barrier sheeting was removed prior to spray foam insulation, and as a result the spray foam stuck to the drywall. Because this seems to be a new problem(and therefore no tools for it), our best solution was using paint scrapers and hammers to chisel it off the spray foam. We managed to get all the drywall off the ceiling this way, but since this is something we will need to fix in the rest of the house, maybe a tool can be created for this by then. :) The only other solution seems to be to cut out the spray foam insulation and drywall all at once, but we aren't wanting to do that for quite a while, at which point we will completely be rebuilding the roof.

Cancer has actually been on a rather steady decline since the early 90s, what’s impressive is that this is despite constant and huge advances in cancer detection and identification! We saw a rapid climb in detection through the middle and alter 1/3 of the law century but that’s largely due to advancing technology making diagnoses possible for more people earlier. It may look like there’s more cancer around than when you were young but remember that with advancing technology comes more refined definitions. There are more known specific types of cancer today, but only because those cancers were either not diagnosed or incompletely diagnosed tue to a lack of tools and knowledge.
